How to Clear Windows Update Cache in Windows 11

Imagine your Windows 11 PC grinding to a halt during updates, throwing endless error codes, or just feeling sluggish overall. Frustrating, right? 😩 The culprit? A cluttered Windows Update cache. Over time, this cache stores temporary files from failed or partial downloads, bloating your system and causing headaches. But don't worry—clearing it is a simple fix that can breathe new life into your device. In this guide, we'll walk you through exactly how to clear Windows Update cache in Windows 11, using safe, official methods. You'll be back to seamless updates in no time, feeling that satisfying speed boost. Let's dive in!

Why You Should Clear the Windows Update Cache in Windows 11

The Windows Update cache acts like a temporary storage bin for update files. It's designed to speed things up by reusing downloaded bits, but when it gets corrupted or overflows, problems arise:

• Slow Performance: Cached files eat up disk space, making your PC lag.
• Update Failures: Errors like 0x80070002 or 0x8007000d often stem from a faulty cache.
• Stuck Downloads: Updates that won't install or keep retrying? Cache overload is likely.
• Security Risks: Outdated or incomplete updates leave vulnerabilities—clearing the cache ensures fresh, reliable installs.

By clearing it, you're essentially hitting a reset button. Microsoft recommends this as a first-line troubleshooting step for Windows 11 update issues. Plus, it's quick—most methods take under 10 minutes. Ready to reclaim your PC's potential? Let's get started with the easiest approaches.

Method 1: Clear Cache Using the Built-in Troubleshooter (Easiest for Beginners) ⭐

No command lines here—this is point-and-click simplicity. Windows 11's troubleshooter automatically detects and clears the Windows Update cache while fixing common glitches. Perfect if you're not tech-savvy.

1. 👆 Press Windows + I to open Settings.
2. Navigate to System > Troubleshoot > Other troubleshooters.
3. Scroll to Windows Update and click Run.
4. Follow the on-screen prompts—it'll scan, clear the cache, and attempt repairs. Restart if prompted.

Voila! Your Windows Update cache is fresh. Test by checking for updates in Settings > Windows Update. If issues persist, move to the next method for a deeper clean.

Method 2: Manual Cache Clear with Disk Cleanup Tool

For a hands-on approach, use the Disk Cleanup tool to target update files directly. This method is great for freeing up gigabytes of space alongside cache clearing.

1. Search for Disk Cleanup in the Start menu and launch it as administrator (right-click > Run as administrator).
2. Select your system drive (usually C:) and click OK.
3. Click Clean up system files—this unlocks advanced options.
4. Check boxes for Windows Update Cleanup, Delivery Optimization Files, and Temporary Files.
5. Hit OK and confirm deletion. Windows will purge the Windows Update cache safely.

Pro tip: Run this monthly to keep things tidy. You'll notice faster boot times and smoother updates. Feeling empowered yet? Keep reading for the command-line power move.

Method 3: Advanced Clear Using Command Prompt (For Power Users) ⚡

If the above didn't fully resolve your Windows 11 update cache woes, dive into Command Prompt. This stops update services, deletes cache folders, and restarts everything—Microsoft's go-to for stubborn issues.

Warning: Run as administrator to avoid permission errors. Here's the step-by-step:

1. Search for cmd, right-click Command Prompt, and select Run as administrator.
2. Stop the services by typing these commands one by one (press Enter after each):

   net stop wuauserv
   net stop cryptSvc
   net stop bits
   net stop msiserver

3. Delete the cache folders. Navigate to C:\Windows\SoftwareDistribution and C:\Windows\System32\catroot2 using:

   ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
   ren C:\Windows\System32\catroot2 Catroot2.old

   (If "ren" fails, use "rd /s /q" to remove them entirely, then recreate with "md".)
4. Restart services:

   net start wuauserv
   net start cryptSvc
   net start bits
   net start msiserver

5. Close Command Prompt, restart your PC, and check for updates.

This wipes the Windows Update cache completely, resolving even deep-seated errors. Users report up to 5GB of space freed—impressive, huh? If you're on the latest Windows 11 build (as of 2026), this method aligns perfectly with Microsoft's updates.
