How to Clear the Cache Windows 10

If your Windows 10 PC has started acting like it’s wading through peanut butterapps taking forever to open, browsers being “dramatic,” or storage mysteriously vanishingcache buildup is often part of the problem.
Cache is basically your computer’s “shortcut stash”: temporary files that help things load faster. The catch? Over time, that stash can get bloated, outdated, or corruptedturning “shortcut” into “speed bump.”

This guide walks you through the safest, most effective ways to clear cache on Windows 10: temporary system files, browser cache, DNS cache, Microsoft Store cache, thumbnails, and even the Windows Update cache (when it’s misbehaving).
We’ll keep it practical, a little funny, and very copy/paste-friendly.

What “Cache” Means on Windows 10 (And Why You Should Care)

On Windows 10, “cache” isn’t just one thing. It’s a collection of different temporary storage bucketssome for Windows itself, some for apps, and some for the internet.
Clearing cache can help when:

• Windows feels sluggish or storage is running low
• A website looks broken or won’t load correctly
• Apps crash, freeze, or display outdated data
• Network problems feel “random” (hello, DNS cache)
• Windows Update keeps failing or getting stuck

Important reality check: clearing cache won’t magically turn a 2012 laptop into a gaming beast. But it can remove junk, fix weird glitches, and free up space without deleting your personal files.

Before You Clear Cache: 60-Second Safety Checklist

• Close your apps (especially browsers) so cache files aren’t “in use.”
• Expect sign-outs in browsers if you remove cookies (cache ≠ cookies, but they live next door).
• Don’t panic if some files won’t deleteskip what Windows says is in use.
• If you’re low on storage, start with Windows Temporary Files and the Downloads folder review (carefully).

Method 1: Clear Windows Temporary Files (The Big One)

This is the most common “Windows 10 cache” people mean: temporary files, system logs, delivery optimization leftovers, DirectX shader cache, thumbnails, and more.
Windows gives you built-in tools for this, and they’re the safest place to start.

Option A: Use Storage & Temporary Files (Fast + Safe)

1. Click Start → Settings.
2. Go to System → Storage.
3. Open Temporary files (or Cleanup recommendations depending on your Windows 10 build).
4. Select categories you want to remove (like Temporary files, Thumbnails, Delivery Optimization files).
5. Click Remove files or Clean up.

Heads-up: You may see “Previous Windows installation(s)” (Windows.old). That can free a lot of space,
but once it’s gone, you typically can’t roll back to the previous Windows version. So only delete it if you’re sure you don’t need that rollback option.

Option B: Turn On Storage Sense (Automatic Cache Cleaning)

If you’d rather Windows quietly handle basic cleanup in the background (like a tidy roommate who doesn’t steal your food), enable Storage Sense.

1. Start → Settings → System → Storage.
2. Toggle Storage Sense to On.
3. Click Configure Storage Sense or run it now (or just Storage Sense) to set a schedule.
4. Choose when it runs and what it cleans (Recycle Bin, temporary files, Downloads folder timing, etc.).

Pro tip: Set Storage Sense to run when disk space is low. It’s like having a “low fuel light” that also refills the tank… kinda.

Method 2: Run Disk Cleanup (Classic, Powerful, Still Useful)

Disk Cleanup is the old-school Windows tool that still does a great job clearing system junk: temporary internet files, error reports, thumbnails, old update files, and more.
It’s especially helpful when you want one “sweep” instead of clicking through multiple settings screens.

How to Run Disk Cleanup

1. In the Start menu search, type Disk Cleanup and open it.
2. Select your main drive (usually C:), then click OK.
3. Check items you want to delete (common: Temporary files, Thumbnails, Temporary Internet Files).
4. For a deeper clean, click Clean up system files and re-check items after it rescans.
5. Click OK → Delete Files.

If you like keyboard shortcuts: press Win + R, type cleanmgr, and press Enter.

Method 3: Manually Clear Temp Folder Cache (When You Want Control)

Windows and apps dump temporary files into specific folders. Clearing them can free space and fix odd app behavior.
The only “rule” is: delete contents, not the folder itselfand skip files Windows won’t let you remove.

Clear Your User Temp Folder (%temp%)

1. Press Win + R.
2. Type %temp% and press Enter.
3. Press Ctrl + A to select everything.
4. Press Delete. If prompted, allow admin permission.
5. If Windows says a file is in use, choose Skip.

Optional: Clear the System Temp Folder (Admin-Friendly)

1. Press Win + R, type C:WindowsTemp, press Enter.
2. Select what you can and delete. Skip anything in use.

This manual approach is great when a specific app is acting haunted. But for everyday cleanup, Storage + Disk Cleanup is usually easier and safer.

Method 4: Clear Browser Cache (Edge, Chrome, Firefox)

Browser cache stores images, scripts, and site data so pages load faster. When it goes stale, you get classic symptoms:
broken layouts, infinite loading spinners, or a site that insists it’s 2019 forever.

The Universal Shortcut

In most browsers, pressing Ctrl + Shift + Delete opens the “Clear browsing data” screen.
Look for Cached images and files (wording varies) and choose a time range like “All time” if you want a full reset.

Microsoft Edge (Windows 10 Default)

1. Open Edge → click the three dots menu.
2. Go to Settings → Privacy, search, and services.
3. Under Clear browsing data, click Choose what to clear.
4. Select Cached images and files (and optionally cookies/history).
5. Click Clear now.

Google Chrome

1. Open Chrome → click the three dots menu.
2. Select Delete browsing data.
3. Pick a time range (like All time).
4. Check Cached images and files → click Delete data.

Mozilla Firefox

1. Open Firefox → menu → Settings.
2. Go to Privacy & Security.
3. Under Cookies and Site Data, click Clear Data.
4. Select cached web content → clear.

Tip: If a single website is glitching, try clearing cache for a shorter time range first (like “Last 24 hours”) before going nuclear.

Method 5: Flush the DNS Cache (For Internet Weirdness)

DNS cache is like your PC’s “address book” for websites. If it gets outdated or corrupted, you may see:
sites not loading, wrong pages, or network hiccups that make you blame your router (sometimes correctly).

Flush DNS Cache Using Command Prompt

1. Open Start and search Command Prompt.
2. Right-click → Run as administrator.
3. Type: ipconfig /flushdns and press Enter.

Flush DNS Using PowerShell (Alternative)

1. Right-click Start → Windows PowerShell (Admin).
2. Run: Clear-DnsClientCache

This doesn’t erase your browsing history. It just tells Windows, “Hey, stop trusting your memory for a second and ask the DNS server again.”

Method 6: Clear Microsoft Store Cache (If Store Apps Won’t Behave)

If Microsoft Store won’t open, downloads get stuck, or app installs refuse to cooperate, clearing the Store cache is often the first fix.

Use wsreset.exe (Built-In Store Cache Reset)

1. Press Win + R.
2. Type: wsreset.exe and click OK.
3. A blank command window may appear briefly, then the Store opens.

If that doesn’t help, the next step is usually resetting the Microsoft Store app from Windows Settings (Apps → Microsoft Store → Advanced options → Reset),
but try wsreset first because it’s quick and low-risk.

Method 7: Clear the Windows Update Cache (Only When Updates Are Stuck)

Most people never need to touch this. But if Windows Update keeps failing with download errors or gets stuck in a loop,
clearing the update cache can remove corrupted update files so Windows can re-download clean copies.

Safer First Step: Run the Windows Update Troubleshooter

1. Start → Settings → System → Troubleshoot → Other troubleshooters.
2. Find Windows Update → click Run.

Manual Method: Clear SoftwareDistribution (Update Cache Folder)

1. Press Win + R, type services.msc, press Enter.
2. Find Windows Update → right-click → Stop.
3. Open File Explorer and go to: C:WindowsSoftwareDistribution
4. Delete the contents inside that folder (not the folder itself).
5. Go back to Services → right-click Windows Update → Start.

After this, Windows Update may take longer the next time it checks for updatesbecause you basically wiped its “downloaded update memory.”
That’s normal.

Method 8: Clear Thumbnail Cache (When Folder Previews Look Wrong)

Thumbnail cache stores those tiny preview images you see in folders. If thumbnails show the wrong image, don’t load, or look corrupted,
clearing the thumbnail cache can fix it.

The simplest way: run Disk Cleanup and check Thumbnails. It removes the old thumbnail cache and Windows rebuilds it as needed.

How Often Should You Clear Cache on Windows 10?

• Temporary files cache: monthly, or when storage gets tight
• Browser cache: when websites glitch, or every 1–3 months
• DNS cache: only when you have network/DNS issues
• Microsoft Store cache: only when Store/App installs act up
• Windows Update cache: only when updates fail repeatedly

Troubleshooting: “It Won’t Let Me Delete These Files”

Totally normal. Cache files are often “in use.” Here’s what to do:

• Skip files Windows says are in use (don’t fight it).
• Restart and try again (a reboot releases a lot of locked files).
• Try cleaning right after startup, before opening a dozen apps.
• If Windows Update cache cleaning feels scary, use the troubleshooter first.

Quick Cheat Sheet: Best Cache-Clearing Order

1. Settings → Storage → Temporary files / Cleanup recommendations
2. Disk Cleanup (with “Clean up system files” if needed)
3. Browser cache (Edge/Chrome/Firefox)
4. DNS flush (only for network issues)
5. Microsoft Store cache (wsreset.exe)
6. Windows Update cache (only if updates fail repeatedly)

Conclusion

Clearing cache on Windows 10 is one of the easiest maintenance wins you can do without risking your personal files.
Start with Temporary Files and Disk Cleanup, then target browser cache or DNS cache when symptoms point that way.
If Windows Update or Microsoft Store is acting stubborn, clear those caches as a focused “reset button,” not a daily habit.

Real-World Experiences Clearing Cache on Windows 10 (What Actually Happens)

Here’s what clearing cache looks like in the real worldwhere the PC isn’t a clean lab machine, but a chaotic little ecosystem full of half-installed apps,
old downloads, and at least one browser tab playing music you can’t find.

Experience #1: The “Why Is My C: Drive Full Again?” moment.
A common Windows 10 story: you swear you didn’t download anything huge, but your drive is suddenly in the red.
In many cases, it’s not one giant fileit’s death by a thousand paper cuts: temporary files, Delivery Optimization leftovers, old logs, shader caches, thumbnails,
and (sometimes) Windows.old after an update. Running Settings → Storage → Temporary files can feel like opening a junk drawer and finding three tape measures.
You select what you recognize, clean it, and suddenly you’ve got breathing room again. The biggest surprise for most people is that Windows can safely remove a lot
without touching personal documentsso long as you read the categories and avoid nuking Downloads without checking.

Experience #2: The “This website is broken… only on my computer” drama.
Browser cache issues are sneaky because the site works fine on your phone, fine on your friend’s laptop, and fine in an incognito windowso your brain concludes:
“The internet is gaslighting me.” Usually it’s cached site data that’s out of sync with a recent website update. Clearing cached images and files often fixes it instantly.
What people notice next: the website loads slightly slower the first time (because the browser has to rebuild the cache), then normal speed returns.
The bonus lesson: you don’t always need to clear everythingsometimes clearing the last 24 hours or the last week is enough to stop the glitch without logging out of every site.

Experience #3: The “Wi-Fi is connected but nothing loads” panic.
When the network is connected but websites refuse to loador only some doDNS cache can be the hidden culprit.
Flushing DNS feels almost too easy: one command, done. But the real value is what it rules out. After an ipconfig /flushdns,
Windows stops relying on potentially stale local DNS entries and asks the DNS server again. If things immediately work, you’ve confirmed it wasn’t your browser cache,
it wasn’t “the whole internet,” and it probably wasn’t your laptop secretly holding a grudge. If it doesn’t work, you still gained claritytime to check the router,
VPN, or actual ISP issues.

Experience #4: The “Windows Update is stuck at 0% (and my blood pressure is stuck at 100%)” scenario.
Most of the time, letting Windows Update do its thing works. But when updates fail repeatedly with missing/corrupt download errors, clearing the update cache can be the reset it needs.
The first time you open Services and stop Windows Update, it feels more serious than it is. Deleting the contents of C:WindowsSoftwareDistribution looks dramatic,
but it’s basically removing the “download staging area” so Windows can start fresh. Afterward, the next update check may take longer, and that’s normalWindows is rebuilding its cache.
The key takeaway: treat Windows Update cache clearing as a troubleshooting step, not a routine cleaning habit.

Experience #5: The “Microsoft Store won’t open, so I guess apps are illegal now?” glitch.
Store problems are often solved by wsreset.exe. People are surprised by how anticlimactic it is: a blank window pops up, closes, and the Store launches again.
It’s one of those fixes that feels like magic until you remember it’s just clearing a cache that got corrupted. If it doesn’t fix the issue, it’s still a smart first step
because it’s low-risk and fastand it helps you narrow down whether the problem is cache-related or something deeper (like account sync, system files, or network restrictions).

Bottom line: clearing cache doesn’t “clean your whole PC” in the spring-cleaning sense, but it often removes the exact stuff that causes the weird, specific problems people actually hate:
broken websites, mysterious storage loss, update loops, and apps that refuse to behave. It’s less about making Windows perfect and more about making it predictable again.
