Learning how to clear computer cache is one of the simplest yet most impactful ways to boost your system’s performance. Over time, cached files accumulate and slow down your device, consuming valuable storage space. This quick guide walks you through clearing cache on Windows, Mac, and browsers in just minutes.
Quick Answer: To clear computer cache, press Ctrl + Shift + Delete in your web browser to open the clear browsing data window. Check the box for “Cached images and files,” select “All time” as the time range, then click “Clear data.” This removes temporary files that slow down your computer and takes about 30 seconds.
- Cache is just temporary files your computer stores to load websites faster, but they pile up over time
- Clearing cache is completely safe and won’t delete your passwords, bookmarks, or personal files
- You should clear cache every few months to keep your computer running smoothly
- The process takes less than a minute and works the same way in most browsers
- Different Windows versions (Windows 7, 10, and 11) all use the same basic steps
What Is Cache and Why Does It Matter?
Think of cache like a notepad your computer keeps. When you visit a website, your computer saves small pieces of that site—like images and page layouts. Next time you visit, your computer pulls from the notepad instead of downloading everything again. This makes websites load faster.
But here’s the problem: that notepad gets messy over time. Old files pile up. Outdated information sticks around. Your computer slows down because it’s sorting through hundreds or thousands of temporary files.
According to AARP, 91% of adults 50+ now own a smartphone, yet many still struggle with everyday tech problems. Clearing cache is one of the simplest fixes that makes a real difference.
How to Clear Computer Cache on Windows 11
If you have Windows 11, the process is simple. You’ll clear cache through your web browser, not through Windows settings. Most people browse with Google Chrome, Microsoft Edge, or Firefox.
For Google Chrome on Windows 11
- Open Google Chrome: Click the Chrome icon on your desktop or taskbar. The window that opens shows your browser.
- Use the keyboard shortcut: Press Ctrl + Shift + Delete all at once. A small window pops up with the title “Clear browsing data.” Don’t worry if you pressed the wrong keys—just try again.
- Choose what to clear: You’ll see checkboxes. Make sure “Cached images and files” is checked. You can leave “Cookies and other site data” checked too—this is safe.
- Select the time range: Click the dropdown menu at the top that says “Time range.” Choose “All time” to clear everything.
- Click the blue button: Click “Clear data” and wait a few seconds. Chrome will show you when it’s done.
The Windows 11 shortcut key method (Ctrl + Shift + Delete) works in almost every browser. It’s the same whether you’re on Windows 11, Windows 10, or even Windows 7.
How to Clear Computer Cache on Windows 10
The steps for how to clear computer cache on Windows 10 are identical to Windows 11. Microsoft Edge is the default browser on Windows 10, so let’s walk through that.
- Open Microsoft Edge: Click the blue and green wave icon on your taskbar.
- Press Ctrl + Shift + Delete: This opens the “Clear browsing data” window.
- Check the right boxes: Make sure “Cached images and files” is checked. You can also check “Cookies and site data” if you want a deeper clean.
- Select “All time”: This clears everything, not just the last hour or day.
- Click “Clear now”: Edge will clear the cache in seconds.
If you prefer Chrome or Firefox on your Windows 10 laptop, the steps are the same as in the Windows 11 section above. The browser matters more than the Windows version.
How to Clear Computer Cache on Windows 7
Windows 7 is older, but many people still use it. The good news: clearing cache works the same way. If you’re using Internet Explorer (the default browser on Windows 7), here’s what to do:
- Open Internet Explorer: Look for the blue “e” icon.
- Click the gear icon: It’s in the top-right corner. Click it, then select “Internet options.”
- Find the “Delete” button: Under “Browsing history,” click “Delete.” A new window opens.
- Check “Temporary Internet files”: Make sure this box is checked. Leave “Preserve Favorites website data” checked if you want to keep your favorite sites loading quickly.
- Click “Delete”: Wait a moment while Internet Explorer clears the cache.
If you use Chrome or Firefox on Windows 7, the Ctrl + Shift + Delete shortcut still works just fine.
How to Clear Computer Cache and Cookies Together
You might hear “cache” and “cookies” mentioned together. Cookies are tiny files that remember your login info and preferences on websites. Clearing both at once gives your browser a fresh start.
The process is almost identical to clearing just cache. When you press Ctrl + Shift + Delete, check both “Cached images and files” and “Cookies and other site data.” Then click “Clear data.”
You won’t lose important files or documents. Your downloads, photos, and Word files stay safe. You might need to log in to some websites again, but that’s normal. According to Microsoft’s official guidance, clearing cookies and cache regularly is a healthy practice for browser performance.
How to Clear Computer Cache on Mac
If you use a Mac instead of Windows, the process is slightly different but still simple. Most Mac users browse with Safari or Chrome.
For Safari on Mac
- Open Safari: Click the compass icon in your dock.
- Go to Safari menu: Click “Safari” in the top-left corner of your screen.
- Click “Clear History”: A small window opens asking how far back to clear.
- Choose “all history”: Select this from the dropdown menu, then click “Clear History.”
For Chrome on Mac
- Open Chrome: Click the Chrome icon.
- Press Command + Shift + Delete: This is the Mac version of the Windows shortcut.
- Check “Cached images and files”: Make sure this box is checked.
- Select “All time” and click “Clear data”: Chrome will clear the cache immediately.

How to Clear Computer Cache Using Command Prompt (Advanced)
Some people prefer using command prompt to clear system cache on Windows 11 or Windows 10. This is a more technical approach, but it’s still safe if you follow the steps exactly.
- Press the Windows key: Type “cmd” in the search box.
- Right-click “Command Prompt”: Select “Run as administrator.” A black window opens.
- Type this command: Type wsreset.exe and press Enter. This clears the Microsoft Store cache specifically.
- Wait for the Store to open: The command works in the background. When the Microsoft Store opens, the cache is cleared.
For most people, the browser method is easier. But if you’re comfortable with command prompt, this method works well for clearing system-level cache on Windows 11 command prompt.
Is It Okay to Clear the Cache on a Computer?
Yes, it’s completely safe. Clearing cache is routine maintenance, like cleaning out your garage. You’re not deleting anything important—just temporary files your computer doesn’t need anymore.
Many people worry they’ll break something. But browsers are designed for this. In fact, tech support experts recommend clearing cache every few months. It helps pages load correctly and can fix odd website behavior.
If your computer is running slowly, clearing cache is one of the first things we check. It’s often part of our slow computer fix service.
Will I Lose Anything if I Clear the Cache?
You won’t lose anything important. Your photos, documents, emails, and downloads stay exactly where they are. Cache only contains temporary copies of website images and page layouts.
Here’s what stays safe when you clear cache:
- Your saved passwords (unless you also check “Passwords” in the clear data window)
- Your bookmarks and favorites
- Your files in Documents, Pictures, Downloads, and Desktop folders
- Your email messages
- Any software you’ve installed
The only small change: some websites might load a bit slower the first time you visit after clearing cache. That’s because your browser has to download images fresh. But after that first visit, things speed back up.
What Happens If You Never Clear Your Cache?
If you never clear cache, your computer gradually slows down. Old files pile up in the background. Your browser tries to sort through thousands of temporary files every time you go online.
You might also see outdated versions of websites. For example, a store’s website might show last month’s sale instead of this month’s prices. Clearing cache fixes these display problems instantly.
Over time, a full cache can also take up gigabytes of space on your hard drive. That’s space you could use for photos or documents instead.
When Should You Ask for Help Instead of Fixing It Yourself?
Most people can clear cache on their own. But sometimes it makes sense to call for help. Here’s when:
- Your computer is still slow even after clearing cache—there might be a deeper issue
- You’re uncomfortable pressing keyboard shortcuts or following technical steps
- You’ve cleared cache but websites still look broken or won’t load
- You want someone to walk you through it step-by-step while they watch your screen
