Delete Old Windows Update Files in Windows 10 and Windows 11

Windows updates help keep your computer secure, stable, and up to date. However, once an update has been installed, Windows often leaves behind temporary installation files, cached data, and previous update files. Over time, these files can take up several gigabytes of storage. Learning how to delete old Windows update files in Windows is a simple way to recover valuable disk space without affecting your system.

Most of these files are no longer needed after a successful update. Removing them can free storage, improve system organisation, and make room for future updates. The key is knowing which files are safe to delete and which should be left untouched.

This guide explains why Windows stores update files, when they can be removed safely, and the best methods to clean them without causing problems.

If you'd rather prevent unnecessary downloads in the future, our guide on How can I stop Windows 10 automatic updates explains the available options. 

Why Should You Delete Old Windows Update Files?

Windows keeps update files for installation, recovery, and rollback purposes. Once your PC is running normally after an update, many of these files become unnecessary. Removing them helps recover storage while keeping your Windows installation clean and organised.

What Are Windows Update Files?

Whenever Windows installs an update, it saves several types of files to support the installation process and future recovery. While some files are removed automatically, others remain on your computer until they are cleaned manually.

These files typically include:

• Temporary update installation files

• Windows Update cache

• Previous update packages

• System rollback files

• Update log files

Keeping these files for too long can reduce the amount of available storage, especially after major Windows feature updates.

When Should You Delete Old Update Files?

Performing Windows Update Cleanup is recommended only after confirming that your computer is working properly. Once you're satisfied with the update, removing unnecessary files is a safe way to recover storage space.

Consider deleting old update files if:

• Your storage space is running low.

• Windows updates have installed successfully.

• You no longer need to roll back to a previous version.

• Large feature updates have left temporary files behind.

• You want to free up space for future updates.

After confirming everything is working as expected, you can use the built-in Windows tools in the next section to remove these files safely.

How to Delete Old Windows Update Files

Windows provides several built-in tools that allow you to remove unnecessary update files safely. These methods only delete files that are no longer required and do not affect the normal operation of your computer. Before starting, make sure any recent Windows update has been installed successfully and your system is working as expected.

Use Disk Cleanup

Disk Cleanup is one of the easiest ways to remove outdated Windows update files. It scans your system for unnecessary files and allows you to delete them with just a few clicks. This method is recommended for most users because it only removes files that Windows considers safe to delete.

Follow these steps:

1. Press Windows + S and search for Disk Cleanup.

2. Select your C: drive and click OK.

3. Click Clean up system files.

4. Tick Windows Update Cleanup and any other files you want to remove.

5. Click OK, then select Delete Files to begin the cleanup.

Once the process is complete, restart your computer to ensure all unnecessary update files have been removed.

Delete the Windows Update Cache

If updates continue to fail or old download files remain on your system, clearing the delete Windows update cache folder can help. This removes temporary update downloads without affecting your personal files. It is also a useful method when you want to clean Windows update files before downloading updates again.

Complete the following steps:

1. Press Windows + R, type services.msc, and press Enter.

2. Stop the Windows Update service.

3. Open C:\Windows\SoftwareDistribution\Download.

4. Delete the files inside the Download folder.

5. Restart the Windows Update service and check for updates again.

After clearing the cache, Windows will automatically download fresh update files the next time you check for updates, helping to avoid problems caused by corrupted or incomplete downloads.

Remove Old Windows Installation Files

If you have recently installed a major Windows update, your computer may still contain files from the previous version. These files are stored to give you the option of rolling back if something goes wrong. Once you are confident that everything is working properly, you can safely remove these files to recover a significant amount of storage space.

Delete the Windows.old Folder Safely

The Windows.old folder contains files from your previous Windows installation. While it is useful if you need to return to an earlier version of Windows, it can occupy several gigabytes of storage. If you no longer need the rollback option, you can delete Windows.old folder safely using the built-in cleanup tools.

Follow these steps:

1. Open Settings.

2. Go to System > Storage.

3. Select Temporary files.

4. Tick Previous Windows installation(s).

5. Click Remove files.

Once the folder has been deleted, you will no longer be able to roll back to your previous Windows version, so make sure your system is running correctly before removing it.

Remove Old Windows Update Files from Settings

Windows Settings also provides a simple way to remove old Windows update files without using additional software. The Temporary Files section identifies update files that are no longer needed and allows you to remove them safely in just a few clicks.

Use the following steps:

1. Open Settings.

2. Navigate to System > Storage.

3. Click Temporary files.

4. Select the old Windows Update files you want to remove.

5. Click Remove files to begin the cleanup.

After the cleanup is complete, restart your computer to allow Windows to finish removing any remaining temporary update files and reclaim the available storage space.
