How to Safely Clear the Windows Update Cache to Fix Update Issues (2025 Guide)

A person sitting at a desk with a laptop, frustrated by a Windows Update error. The screen shows a warning message and a progress bar stuck in place, illustrating the concept of update cache issues.

Feeling Stuck with Windows Updates? Clearing the Cache Might Help

Have you ever tried to quickly get your work done, only to find Windows Update acting up—stuck, throwing errors, or slowing down your system?

One of the lesser-known but surprisingly common causes of update failures is the Windows Update cache. Over time, this cache can become cluttered with old or corrupted files, preventing new updates from being applied properly.

In this guide, we’ll walk you through how to safely clear the Windows Update cache, explain which folders can be deleted, which ones you should never touch, and offer additional troubleshooting tips if clearing the cache isn’t enough.

Step-by-Step: How to Clear the Windows Update Cache

  1. Stop the Windows Update service
    – Press Windows + R, type services.msc, and press Enter.
    – Find “Windows Update” in the list, right-click it, and choose Stop.
  2. Delete files inside the cache folders
    – Navigate to: C:\Windows\SoftwareDistribution
    – Open both the Download and DataStore folders.
    – Delete all files and folders inside them.
    ⚠️ Do not delete the SoftwareDistribution folder itself.
  3. Restart the Windows Update service
    – Go back to services.msc, right-click “Windows Update”, and click Start.
  4. Restart your PC
    – A reboot ensures that the changes take full effect.

What These Folders Contain — and Why It’s Safe to Clear Them

1. Download Folder

This contains temporary files downloaded for Windows updates. Once the updates are installed (or fail to install), these files are often no longer needed. It’s safe to delete them — Windows will redownload anything it needs later.

Note: Only delete the contents, not the folder itself.

2. DataStore Folder

This folder holds logs and metadata related to your update history. Deleting its contents will reset your update history view in Settings, but it won’t remove any installed updates. It’s safe to clear if you’re troubleshooting.

⚠️Never Delete These Folders

  • The SoftwareDistribution folder itself
  • EventCache folder (if present)
  • Any other subfolders you don’t recognize — unless you know exactly what they are for

These folders are critical to the functioning of Windows Update. Deleting them entirely may cause severe issues that require system repair.

Still Not Working? Try These Advanced Commands

If clearing the cache didn’t fix the problem, these system-level repair tools often help:

  1. SFC (System File Checker)
    – Open Command Prompt as Administrator
    – Run: sfc /scannow
    This scans and repairs system file corruption.
  2. DISM (Deployment Image Servicing and Management)
    – Run these commands in order:
    DISM /Online /Cleanup-Image /CheckHealth
    DISM /Online /Cleanup-Image /ScanHealth
    DISM /Online /Cleanup-Image /RestoreHealth
    These commands check and repair the system image that Windows uses for updates.

June 2025 Update Notes

  • Some users have experienced failures with KB5060842 and KB5063060. Manually clearing the cache may help in those cases.
  • Windows 11 24H2 has introduced new update bugs, including frozen update progress and post-update freezes.
  • When using Storage Sense (Settings > System > Storage), make sure it doesn’t automatically delete important temp files related to ongoing updates.

Pro Tip: Use Standalone Installers

If all else fails, you can manually download the update from the Microsoft Update Catalog and run the .msu file. This bypasses the built-in update process and often succeeds where automatic updates fail.

Frequently Asked Questions

  • Q: Is it okay to delete the SoftwareDistribution folder?
    A: No. Only delete the contents of Download and DataStore folders inside it.
  • Q: Will clearing the cache remove installed updates?
    A: No. Installed updates remain; only history and temporary files are affected.
  • Q: Can I do this regularly?
    A: It’s not necessary unless you’re actively troubleshooting update errors.

Final Thoughts

Knowing how to clear the Windows Update cache can save you a lot of time and frustration. It’s a simple but powerful step when your PC refuses to update properly.

That said, always proceed carefully when modifying system files or folders — and if you’re unsure, consult a trusted technician or IT support service.

Stay updated, stay safe — and don’t forget to back up your data regularly!
