How to Clean Windows 11 Update Cache: Step-by-Step Guide to Fix Update Errors

Windows 11 updates can sometimes get stuck or fail due to corrupted cache files. Cleaning the update cache is a simple way to fix these common update errors. This process helps your system download fresh update files without interference from old or damaged data.

In this guide, you will learn how to clear the Windows 11 update cache step-by-step. The instructions are designed for users of all levels, so no advanced knowledge is needed.

Following these steps carefully can save you from lengthy troubleshooting and keep your device running smoothly. Let’s start with some quick notes before diving into the process.

Cleaning the update cache does not delete your personal files or settings. It only removes temporary files related to Windows updates.

Quick Note: Prerequisites and Checks Before You Start

Make sure you have administrator rights on your Windows 11 device. You will need these permissions to stop services and delete system files.
Close all running applications to avoid conflicts during the process.
Ensure your device is connected to a stable internet connection for downloading updates after cleaning the cache.
It is recommended to create a system restore point as a precaution in case anything goes wrong.

Step 1: Stop Windows Update Service

Before deleting the update cache, you need to stop the Windows Update service. This prevents the system from using or locking update files while you clear the cache.

Press Windows + S to open the search box.
Type Services and click the Services app from the results.
In the Services window, scroll down and find Windows Update.
Right-click on Windows Update and select Stop. Wait a few seconds for the service to stop.

Stopping this service is essential because it locks the update cache folder during operation, making it impossible to delete its contents while running.

Step 2: Delete the Update Cache Files

Now that the Windows Update service is stopped, you can safely delete the cache files that might be causing update errors.

Open File Explorer by pressing Windows + E.
Navigate to the following folder: C:WindowsSoftwareDistributionDownload
Select all files and folders inside the Download folder by pressing Ctrl + A.
Right-click the selected items and choose Delete. If prompted for administrator permission, click Yes.

Deleting these files removes the old update data, forcing Windows to download fresh update files during the next update check.

Step 3: Restart the Windows Update Service

After clearing the cache, start the Windows Update service again to resume normal update operations.

Return to the Services window.
Right-click on Windows Update and select Start.
Wait a few seconds to ensure the service restarts properly.

Restarting the service allows Windows to recognize the cleared cache and proceed with downloading updates without errors.

Step 4: Check for Updates

Finally, verify if the issue is resolved by checking for updates manually.

Click the Start button and open Settings (or press Windows + I).
Go to Windows Update on the left menu.
Click Check for updates and wait for Windows to search and download available updates.

If updates download and install successfully, the cache cleaning process has resolved the problem.

Alternative Method: Using Command Prompt to Clear Update Cache

If you prefer using the command line, you can clear the update cache by running a few commands. This method is useful for advanced users or when you want to automate the process.

Press Windows + S, type cmd, then right-click Command Prompt and select Run as administrator.
Stop the Windows Update service by typing the following command and pressing Enter:
net stop wuauserv
Delete the update cache files with this command:
del /f /s /q %windir%SoftwareDistributionDownload*
Restart the Windows Update service by typing:
net start wuauserv
Close the Command Prompt window.

This command-line method accomplishes the same results but requires careful attention to commands and permissions.

Frequently Asked Questions (FAQs)
