This guide walks you through several methods — from the built-in tools Windows already gives you to a few manual tricks worth knowing. Pick whichever approach suits you best.

What Are Temporary Files, Exactly?

Temporary files are created by Windows and your applications as they work. Installers unpack files they need only during setup. Browsers cache images and scripts so pages load faster on your next visit. Windows Update keeps old copies of system files in case something goes wrong. These files are meant to be short-lived, but Windows doesn’t always clean them up automatically.

Common types include:

• System temp files — stored in C:\Windows\Temp
• User temp files — stored in %AppData%\Local\Temp
• Browser cache — varies by browser, but usually several hundred megabytes
• Windows Update cache — can grow to several gigabytes after major updates
• Recycle Bin contents — files you deleted but haven’t permanently removed
• Thumbnail cache — previews Windows generates for images and videos

None of these are essential to keep. Deleting them is safe.

Method 1: Use Storage Sense

Storage Sense is Microsoft’s built-in cleanup tool. It can run automatically on a schedule, which means you can set it once and largely forget about it.

Turn on Storage Sense

1. Open Settings (press Windows + I).
2. Go to System > Storage.
3. Toggle Storage Sense to On.
4. Click Storage Sense (the text link, not just the toggle) to open its settings.
5. Choose how often it should run — options include every day, every week, or every month. Every month is a sensible default for most people.
6. Set when to delete files in your Recycle Bin and Downloads folder automatically, if you want that.

Run it manually right now

At the bottom of the Storage Sense settings page, you’ll see a Run Storage Sense now button. Click it for an immediate cleanup without waiting for the schedule.

Method 2: Disk Cleanup

Disk Cleanup has been part of Windows for decades. It’s straightforward and gives you a clear list of what it will delete before it does anything.

1. Press Windows + S and type Disk Cleanup, then open it.
2. Select the drive you want to clean — usually C: — and click OK.
3. Windows scans the drive and shows you a list of file categories with checkboxes. Each one shows how much space you’ll recover.
4. Tick the categories you want to remove. Safe choices include Temporary files, Temporary Internet Files, Recycle Bin, and Thumbnails.
5. Click OK, then Delete Files to confirm.

Clean up system files too

For a deeper clean, click Clean up system files in the same window. This requires administrator rights and scans for larger items like Windows Update Cleanup — old update files that Windows keeps around after installing patches. This category alone can free up several gigabytes on a system that’s been running for a while.

Method 3: Delete Temp Files Manually

Sometimes you want to go straight to the source. Here’s how to clear the temp folders directly.

Clear the user temp folder

1. Press Windows + R to open the Run dialog.
2. Type %temp% and press Enter. This opens your personal temp folder.
3. Press Ctrl + A to select everything, then press Delete.
4. Windows may warn you that some files are in use — click Skip for those. Active processes lock their temp files, and that’s fine to leave.

Clear the system temp folder

1. Press Windows + R again.
2. Type temp (without the percent signs) and press Enter.
3. Select all and delete as before, skipping any files that are in use.

You won’t break anything by doing this. If an app needs a temp file that you deleted, it will simply create a new one.

Method 4: Clear the Windows Update Cache

Windows keeps downloaded update files in a folder called SoftwareDistribution. Once updates are installed, those files serve no purpose — but they can take up a lot of space. Clearing them is safe, though it does mean Windows will have to re-download updates if it needs to reinstall them for any reason.

1. Press Windows + S and search for Command Prompt. Right-click it and choose Run as administrator.
2. Type the following commands one at a time, pressing Enter after each:
   
   
   
   • net stop wuauserv
   
   
   • net stop bits
   
   
   
   These stop the Windows Update services so you can safely delete the files.
   
3. Open File Explorer and navigate to C:\Windows\SoftwareDistribution\Download.
4. Select all files and delete them.
5. Go back to the Command Prompt and restart the services:
   • net start wuauserv
   • net start bits

This is the most involved method here, but it’s worth doing if your C: drive is running low and Disk Cleanup alone didn’t free enough space.

Method 5: Clear Your Browser Cache

Browser caches aren’t technically Windows temp files, but they live on your drive and can grow surprisingly large. Here’s the quick path for the most common browsers:

• Chrome: Press Ctrl + Shift + Delete > set time range to All time > tick Cached images and files > click Clear data.
• Edge: Same shortcut — Ctrl + Shift + Delete — and the same steps.
• Firefox: Ctrl + Shift + Delete > choose Everything from the dropdown > tick Cache > click Clear Now.

Clearing the cache means some websites will load slightly slower on your next visit while they rebuild it. That’s a temporary trade-off.

How Often Should You Do This?

If you turn on Storage Sense with a monthly schedule, you mostly don’t need to think about it. For everyone else, a manual cleanup every one to three months is reasonable. If your drive is consistently near capacity, check more often — or consider whether it’s time for a larger drive or cloud storage for your files. Cleaning temp files is a maintenance task, but if your PC is genuinely slow, other factors — too many startup programs, outdated drivers, or insufficient RAM — may be the real culprits. But clearing out the clutter is always a good first step, and now you know exactly how to do it.

Why CPU Temperature Matters

Modern processors are tough, but heat is still their biggest enemy. When a CPU runs too hot for too long, it will throttle its own speed to protect itself — meaning slower performance exactly when you need it most. In extreme cases, persistent overheating can shorten the lifespan of the chip and other nearby components.

Knowing your CPU temperature helps you spot problems early: a failing cooler, dried-out thermal paste, a dusty heatsink, or simply a case with poor airflow. A quick temperature check takes less than a minute and can save you from an expensive repair later.

What Is a Safe CPU Temperature?

This varies by processor, but as a general guide:

• Idle (desktop, light tasks): 30 °C – 50 °C is comfortable for most CPUs.
• Under load (gaming, video rendering): Up to 80 °C – 90 °C is acceptable for many modern chips, though lower is always better.
• Above 95 °C consistently: This is a warning sign worth investigating.

Always check your specific CPU’s maximum rated temperature (often called T_junction or T_max) on the manufacturer’s website for Intel or AMD. Those numbers are the definitive reference for your chip. In my computer when I develop android application the cpu temperature easily reached at 100-degree C.

Method 1: Check the BIOS / UEFI

Windows 11 does not expose CPU temperature in its native settings app or Task Manager, but your motherboard’s BIOS does. This method requires a reboot, so save your work first.

1. Click Start > Settings > System > Recovery.
2. Next to Advanced startup, click Restart now.
3. Choose Troubleshoot > Advanced options > UEFI Firmware Settings > Restart.
4. Once inside the BIOS, look for a section called Hardware Monitor, PC Health Status, or System Information — the exact name depends on your motherboard brand.
5. You will see the CPU temperature listed there.

This method gives you a snapshot at near-idle conditions. It is useful for a quick sanity check but not practical for monitoring temperature while running games or heavy apps.

Method 2: Use Core Temp

Core Temp is one of the most popular free tools for this job. It is small, straightforward, and shows per-core temperatures in real time.

How to set it up

1. Download Core Temp from alcpu.com (the official site). During installation, watch for any optional bundled software and uncheck it if you do not want it.
2. Run the program. You will immediately see temperature readings for each core of your CPU.
3. The Min and Max columns are especially useful — they record the lowest and highest temperatures since the app launched, so you can stress your system and then check the peak.

Method 3: Use HWiNFO64

If you want more than just CPU temperature, voltages, fan speeds, GPU heat, drive temperatures — HWiNFO64 is the tool professionals reach for. It is free and updated regularly.

1. Download HWiNFO from hwinfo.com and install or run the portable version.
2. Launch it and click Run (or choose Sensors-only mode to skip the summary screen).
3. In the Sensors window, scroll to your CPU section. You will find individual core temperatures, package temperature, and more.
4. Right-click any reading and choose Add to Tray to pin it to your system tray for quick access.

Method 4: Use MSI Afterburner

MSI Afterburner is primarily a GPU overclocking tool, but its on-screen display (OSD) can show CPU temperature as an overlay inside any game. It works on all graphics card brands, not just MSI.

1. Download MSI Afterburner from the official MSI website. It installs alongside RivaTuner Statistics Server — keep both, as RivaTuner powers the overlay.
2. Open Afterburner, go to Settings > Monitoring.
3. Find CPU Temperature in the list, tick it, then enable Show in On-Screen Display.
4. Switch to the On-Screen Display tab and set a hotkey to toggle the overlay.
5. Launch your game and press the hotkey. Your CPU temperature will appear in the corner of the screen.

Method 5: Windows PowerShell

Windows 11 can pull a temperature reading through WMI (Windows Management Instrumentation), though the result is in tenths of a degree Kelvin and needs converting. It is not the most convenient method, but it requires zero extra software.

1. Right-click the Start button and choose Windows Terminal (Admin) or PowerShell (Admin).
2. Paste this command and press Enter:

Get-WmiObject MSAcpi_ThermalZoneTemperature -Namespace "root/wmi" | Select-Object CurrentTemperature

Divide the number you get by 10, then subtract 273.15 to convert from Kelvin to Celsius. For example, a result of 3232 becomes (3232 ÷ 10) ? 273.15 = 49.85 °C.

Note that this reads a thermal zone sensor, which may not match per-core readings from dedicated tools. Treat it as a rough indicator rather than a precise measurement.

What to Do If Your CPU Is Running Hot

If your temperatures are consistently high, here are the most common fixes to try — in order from easiest to most involved:

• Clean the dust. Compressed air in the vents and heatsink fins makes a surprising difference.
• Check your fan curves. Use your motherboard’s software (ASUS Armoury Crate, MSI Center, etc.) to make sure fans ramp up properly under load.
• Reapply thermal paste. On a CPU that is a few years old, dried thermal paste is a very common culprit. A pea-sized dot of fresh paste can drop temperatures by 10 °C or more.
• Improve case airflow. Make sure you have intake fans at the front and exhaust at the rear or top. Cables blocking airflow are worth tidying too.
• Upgrade the cooler. The stock cooler that ships with many CPUs is adequate for normal use but struggles under sustained heavy loads. An aftermarket air cooler or an all-in-one liquid cooler can help significantly.

Final Thoughts

Checking your CPU temperature on Windows 11 is not complicated once you know where to look. Make it a regular habit — especially after moving your PC, installing new hardware, or noticing unusual fan noise. A few seconds of monitoring can tell you a lot about the health of your system and help you catch problems before they turn into costly failures. Stay cool out there.

Why You Might Need to Check Your Specs

Before diving in, here are a few common situations where knowing your hardware details matters:

• Installing software or games — most apps list minimum and recommended system requirements.
• Planning an upgrade — you need to know what’s already inside before buying new components.
• Troubleshooting performance issues — low RAM or an old CPU can explain a lot.
• Selling or buying a second-hand PC — verifying specs protects both parties.

Method 1: System Settings (The Quickest Way)

This is the fastest route for a basic overview — processor, RAM, and Windows edition.

1. Press Windows key + I to open Settings.
2. Go to System, then scroll down and click About.
3. Under Device specifications, you’ll see your processor model, installed RAM, and whether your system is 32-bit or 64-bit.
4. Under Windows specifications, you’ll find your Windows edition and version number.

This screen is great for a quick sanity check, but it doesn’t show your graphics card, storage details, or motherboard. For those, keep reading.

Method 2: System Information (The Most Detailed Built-In Tool)

The System Information panel has been part of Windows for decades and remains one of the most thorough ways to inspect your hardware — all in one place.

How to open it

1. Press Windows key + R to open the Run dialog.
2. Type msinfo32 and press Enter.

The window that opens lists everything from your BIOS version and motherboard manufacturer to your total physical memory. Here’s what to look for in each section:

• System Summary — processor, total RAM, system manufacturer, and model name. This is where you’ll find your motherboard make if you need it.
• Components > Display — your graphics card name and dedicated video RAM.
• Components > Storage > Disks — your hard drives and SSDs, including their size and model number.
• Components > Network > Adapter — your network card details, useful for driver troubleshooting.

Method 3: Device Manager (Best for Checking Drivers)

Device Manager is less about raw specs and more about understanding what hardware Windows has recognised — and whether the drivers are working correctly.

How to open it

• Right-click the Start button and select Device Manager.

Expand any category to see the devices inside. A yellow warning triangle next to a device means Windows is having trouble with it — often a missing or outdated driver. For checking specs, the most useful sections are:

• Display adapters — confirms your graphics card model.
• Processors — lists each logical core of your CPU.
• Disk drives — shows your storage devices by model name.

Method 4: Task Manager (Great for Monitoring in Real Time)

Task Manager isn’t just for closing frozen apps. Its Performance tab gives you a live view of your hardware and shows key specs at the same time.

1. Press Ctrl + Shift + Esc to open Task Manager.
2. Click the Performance tab.
3. Click on CPU, Memory, Disk, or GPU in the left panel.

Each panel shows the component’s model name alongside live usage graphs. On the CPU screen, for example, you can see the number of cores and logical processors. On the Memory screen, you’ll see your total RAM, its speed in MHz, and how many slots are used — very handy if you’re wondering whether you can add another stick.

Method 5: DirectX Diagnostic Tool (Especially Useful for Gaming)

If you’re troubleshooting a game or checking whether your system supports a certain DirectX version, the DirectX Diagnostic Tool (DxDiag) is worth knowing about.

1. Press Windows key + R, type dxdiag, and press Enter.
2. Wait a moment for it to finish loading.

The tool is organised into tabs:

• System — computer name, OS, processor, and RAM.
• Display — GPU name, manufacturer, dedicated memory, and the DirectX feature levels it supports.
• Sound — audio device details.

You can also click Save All Information to export everything to a text file — useful when asking for tech support, because you can share the file instead of trying to read specs out over the phone.

Method 6: Command Prompt (For the Keyboard-Inclined)

If you prefer typing to clicking through menus, a couple of quick commands will pull up your specs in seconds.

Get a full system summary

Open Command Prompt (search for cmd in the Start menu) and type:

systeminfo

Press Enter and wait a few seconds. You’ll get a detailed text readout covering OS version, processor, RAM, network adapters, and more.

Check just your CPU

wmic cpu get name

This returns your processor’s full model name — nothing more, nothing less. Clean and fast.

None of these methods require you to install third-party software, and all of them are available on Windows 10 and Windows 11. Pick the one that fits the situation — or use a couple together if you want to cross-check something.

This guide walks you through exactly how to use AI tools to generate presentation outlines, how to prompt them well, and how to refine what you get so the final result actually sounds like you.

Why AI Is Surprisingly Good at Outlines

A presentation outline is, at its core, a structured list of topics arranged in a logical order. That is a task where AI language models genuinely shine. They have processed enormous amounts of written content — reports, articles, slide decks — so they understand conventional structures like problem-solution, chronological narrative, or compare-and-contrast.

What AI is not good at is knowing your specific audience, your company’s internal context, or the nuances of your subject matter. That is where you come in. Think of the AI as a very fast first drafter, and yourself as the editor who knows what actually matters.

Which Tools to Use

You have several solid options depending on what you already use day to day:

• ChatGPT (OpenAI) — Versatile and conversational. Great for iterating on an outline through back-and-forth dialogue.
• Claude (Anthropic) — Tends to produce well-organized, readable output and handles longer context well.
• Microsoft Copilot — Built into Microsoft 365, so if your organization already uses PowerPoint, it can generate outlines directly inside the app.
• Google Gemini — Integrated with Google Workspace, useful if you work in Google Slides.
• Gamma or Beautiful.ai — Purpose-built presentation tools with AI outline and design generation combined.

For pure outline generation, a general-purpose chat tool like ChatGPT or Claude is usually the fastest starting point. You do not need a subscription to experiment — free tiers work fine for this task.

How to Write a Prompt That Gets Useful Results

The quality of your outline depends almost entirely on the quality of your prompt. A vague prompt produces a generic outline. A specific prompt produces something you can actually use.

The Core Elements of a Good Outline Prompt

1. Topic — What is the presentation about?
2. Audience — Who will be in the room? (Executives, students, clients, colleagues?)
3. Goal — What should the audience do, think, or feel by the end?
4. Length — How many minutes is the presentation, and roughly how many slides?
5. Format preference — Do you want bullet points, numbered sections, or a narrative arc?

A Practical Example

Here is a weak prompt versus a strong one:

Weak: “Give me an outline for a presentation about remote work.”

Strong: “Create a 15-minute presentation outline on the productivity benefits of remote work for a team of mid-level managers at a logistics company. The goal is to persuade them to approve a hybrid work policy. Include an opening hook, three main arguments with supporting points, a section addressing common objections, and a clear call to action. Format it as numbered sections with sub-bullets.”

The second prompt gives the AI enough context to make real decisions. You will notice the output is dramatically more useful — it will feel tailored rather than generic.

Step-by-Step: From Prompt to Polished Outline

Step 1 — Generate Your First Draft

Paste your detailed prompt into your chosen tool and run it. Read the output once without editing. Ask yourself: Does the overall flow make sense? Are the main sections in the right order? Is anything obviously missing or irrelevant?

Step 2 — Iterate with Follow-Up Prompts

You do not have to accept the first result. Use follow-up messages to refine it. For example:

• “Make the opening more attention-grabbing — start with a surprising statistic or a short story instead of a definition.”
• “Combine sections two and three — they overlap too much.”
• “Add a slide for Q&A guidelines at the end.”
• “The tone feels too formal. Rewrite the section headings to sound more conversational.”

This back-and-forth is where AI tools really earn their keep. You are shaping the structure in real time rather than rewriting from scratch.

Step 3 — Add Your Own Knowledge

Once the structure feels right, go through each section and add the specific details only you know: real data from your team, an anecdote from a client meeting, a company-specific challenge. The AI gave you the frame; you are filling it with substance.

Step 4 — Check the Logic

Read the outline out loud, section by section, as if you were presenting it. This catches logical jumps that look fine on screen but feel awkward when spoken. Ask: Does each section lead naturally into the next? Does the ending connect back to the opening?

Step 5 — Move It Into Your Slide Tool

Copy the final outline into PowerPoint, Google Slides, or whichever tool you use. Each main section becomes a slide title; sub-bullets become your speaker notes or on-slide content. If you are using Copilot inside PowerPoint or Gemini inside Google Slides, you can sometimes paste the outline directly and let the tool format it automatically.

Common Mistakes to Avoid

• Accepting the first output without reading it carefully. AI tools can produce outlines that sound plausible but have a strange structure or miss your actual point entirely.
• Using AI-generated section headings word for word. They often sound slightly robotic. Rewrite them in your own voice.
• Skipping the audience step. An outline for a technical developer audience looks very different from one for a board of directors. Specify this every time.
• Treating the outline as finished content. The outline is a map, not the territory. You still need to build the slides and practice the delivery.

A Note on Accuracy

AI tools sometimes include placeholder facts, suggested statistics, or example figures in an outline. Treat all of these as prompts to find real data, not as verified information. Always check any numbers or claims before they appear on a slide — especially if you are presenting to a skeptical audience.

Quick Tips for Getting Even Better Results

• Tell the AI the presentation style you admire — for example, “structure it like a TED Talk” or “keep it straightforward, no gimmicks.”
• If your topic is technical, briefly explain the subject in your prompt so the AI can use the right terminology.
• Ask for two or three alternative structures if you are unsure which approach works best, then pick elements from each.
• Save your best prompts. Once you find a prompt format that works for your context, reuse it with small adjustments each time.

The Bottom Line

Using AI to generate a presentation outline is not about cutting corners — it is about spending your limited time on the parts that require human judgment: the examples, the stories, the nuance, and the delivery. The structural scaffolding is the part that used to eat your morning. Now it takes about thirty seconds.

Start with a specific prompt, iterate quickly, and then put your own expertise into the gaps. That combination — AI speed plus your knowledge — produces outlines that are both well-structured and genuinely useful. Give it a try before your next presentation and see how much time you get back.

This guide walks you through every practical method to compress images in PowerPoint, trim that file size down, and keep your slides looking great in the process.

Why PowerPoint Files Get So Large

Images are almost always the culprit. When you paste or insert a photo into a slide, PowerPoint keeps the full original resolution — even if the image is displayed at a fraction of its actual size. A single smartphone photo can be 5–10 MB on its own. Add a dozen of those and you’re already in trouble before you’ve written a single bullet point.

A few other common causes:

• Embedded fonts — useful for sharing, but they add weight.
• Undo history — PowerPoint sometimes stores edit history inside the file.
• Unused slide masters — leftover layouts from imported themes.
• Audio and video clips — these can dwarf even the largest image collections.

For now, let’s focus on images, since that’s where you’ll win back the most space with the least effort.

Method 1: Use PowerPoint’s Built-In Compress Pictures Tool

This is the fastest route and it’s built right into the app. The steps are slightly different depending on your version, but the logic is the same across Windows and Mac.

On Windows (Microsoft 365 / PowerPoint 2016 and later)

1. Click on any image on your slide to select it.
2. Go to the Picture Format tab that appears in the ribbon.
3. Click Compress Pictures (it looks like two overlapping mountain icons).
4. In the dialog box, choose your target output resolution.
5. Tick Delete cropped areas of pictures — this alone can save significant space.
6. To compress every image in the file at once, uncheck the option that says “Apply only to this picture.”
7. Click OK.

On Mac (Microsoft 365 for Mac)

1. Select an image on your slide.
2. Click the Picture Format tab in the ribbon.
3. Click Compress Pictures.
4. Choose a resolution and make sure “All pictures in this file” is selected.
5. Click OK.

Choosing the Right Resolution

PowerPoint typically offers these options:

• High fidelity — keeps the original. Use this only if you’re printing large format.
• HD (330 ppi) — great for printing standard documents.
• Print (220 ppi) — solid choice for presentations you’ll also print.
• Web (150 ppi) — ideal for presentations shared digitally or shown on a screen.
• Email (96 ppi) — smallest file size; fine for most screen presentations.

Method 2: Delete Cropped Areas of Pictures

This one surprises a lot of people. When you crop an image in PowerPoint, the software hides the cropped portion — but it doesn’t actually delete it. The full original image is still sitting inside your file, invisible but taking up space.

To remove those hidden pixels permanently:

1. Select the image.
2. Go to Picture Format ? Compress Pictures.
3. Check Delete cropped areas of pictures.
4. Click OK.

If you’ve cropped several large photos, this step alone can slash your file size considerably. Just be aware that once you delete the cropped areas, you can’t uncrop those images later — so do this when you’re happy with your layout.

Method 3: Save As to Trigger a File Cleanup

Here’s a quick trick that many people overlook. PowerPoint’s file format (.pptx) is essentially a compressed ZIP archive. Over time, as you edit and undo and re-edit, the file can accumulate redundant data.

Simply doing a Save As — saving the file under a new name or to a new location — forces PowerPoint to write a clean copy of the file, which often reduces the size noticeably without you changing anything else.

1. Go to File ? Save As.
2. Choose your folder and give the file a new name if you like.
3. Click Save.

Compare the file size before and after. You might be pleasantly surprised.

Method 4: Resize Images Before Inserting Them

The most effective long-term habit is to resize your images before they go into PowerPoint. If your slide is displayed at 1920 × 1080 pixels, an image that’s 6000 × 4000 pixels is carrying a lot of unnecessary data from the moment it lands on the slide.

A free tool like Squoosh (squoosh.app) or even the built-in image editors on Windows and Mac can resize and compress photos before you import them. Aim for images that are roughly the size they’ll appear on screen — there’s no benefit to inserting a 20 MB photo if it’s going to be displayed in a 400-pixel-wide box on your slide.

Method 5: Change Image Format Inside the File

If you’re comfortable doing a bit of manual work, you can replace high-resolution PNGs with compressed JPEGs. PNGs are lossless and often much larger than JPEGs for photographic content. For most presentation photos, a JPEG at 80–85% quality is visually identical to the original PNG but a fraction of the size.

You can do this outside PowerPoint:

1. Export or save your images from their source as JPEG files.
2. Delete the existing images from your slides.
3. Re-insert the JPEG versions.

It takes a few extra minutes, but it’s worth it for presentations with many large photos.

Bonus: Check What’s Actually Making Your File Heavy

Because a .pptx file is really a ZIP archive, you can peek inside it to see exactly what’s taking up space:

1. Make a copy of your .pptx file.
2. Rename the copy, changing the extension from .pptx to .zip.
3. Open the ZIP file with your system’s archive tool.
4. Look inside the ppt/media folder — this is where all your images, audio, and video files live.

Sort by file size and you’ll immediately see which assets are the biggest offenders. This makes it easy to decide which images to replace or compress first.

A Few Things to Keep in Mind

• Compression is permanent. Once you compress and save, you can’t restore the original quality from within PowerPoint. Keep a backup of the original file if the images are important.
• Logos and diagrams are different. SVG or high-resolution PNG logos often need to stay sharp. Consider compressing only your photos and leaving graphics alone.
• Video files need separate handling. The Compress Pictures tool doesn’t touch embedded video. For video-heavy presentations, consider linking to video files rather than embedding them.

Quick Summary

To bring a bloated PowerPoint file back to a manageable size, start with the built-in Compress Pictures tool and make sure to delete cropped areas. Follow that with a Save As to clean up the file. For the best results going forward, resize images to an appropriate resolution before you insert them. These steps together can turn an 80 MB presentation into something you can actually attach to an email without breaking a sweat.
