This article describes an update for the Disk Cleanup wizard in Windows 7 Service Pack 1 (SP1).

This update adds a new plugin to the Disk Cleanup wizard.

After you install this update, you can use the Windows Update Cleanup option to delete Windows updates that you no longer need.

Notes

• The Windows Update Cleanup option is available only when the Disk Cleanup wizard detects Windows updates that you do not need on the computer.
• To enable you to roll back to previous updates, updates are stored in the WinSxS store even after they are superseded by later updates. Therefore, after you run the Disk Cleanup wizard, you may be unable to roll back to a superseded update. If you want to roll back to a superseded update that the Disk Cleanup wizard deletes, you can manually install the update.​

After you install this update, follow these steps to clean up Windows update files.

Note You must have administrator permissions to clean up Windows update files.​

◦ Method 1: Click Start, type cleanmgr in the Start Search box, and then click OK.
◦ Method 2: Click Start, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup.
◦ Method 3: If a Low Disk Space notification appears, click the notification to open the Disk Cleanup wizard.​

2. Select the Windows 7 system drive, and then click OK.

Note: This operation might take several seconds because the Disk Cleanup wizard searches for files on the drive that can be cleaned up.​

3. If the Windows Update Cleanup option is not displayed on the Disk Cleanup tab, click Clean up system files. If the Windows Update Cleanup option is displayed on the Disk Cleanup tab, go to step 5.

Note The Windows Update Cleanup option is available only when you log on by using administrator permissions.​
