From Corrine's Security Garden :rose: - Improvement to Windows 7 SP1 Disk Cleanup\n\nkb 2852386 -\n\nThis article describes an update for the Disk Cleanup wizard in Windows 7 Service Pack 1 (SP1).\n\nThis update adds a new plugin to the Disk Cleanup wizard. \n\nAfter you install this update, you can use the Windows Update Cleanup option to delete Windows updates that you no longer need. \n\nNotes\n• The Windows Update Cleanup option is available only when the Disk Cleanup wizard detects Windows updates that you do not need on the computer.\n• To enable you to roll back to previous updates, updates are stored in the WinSxS store even after they are superseded by later updates. Therefore, after you run the Disk Cleanup wizard, you may be unable to roll back to a superseded update. If you want to roll back to a superseded update that the Disk Cleanup wizard deletes, you can manually install the update.\n \n\nClean-up Steps:\n\nAfter you install this update, follow these steps to clean up Windows update files.\n\nNote You must have administrator permissions to clean up Windows update files.\n\n1. Start the Disk Cleanup wizard. To do this, use one of the following methods:\n◦ Method 1: Click Start, type cleanmgr in the Start Search box, and then click OK.\n◦ Method 2: Click Start, click All Programs, click Accessories, click System Tools, and then click Disk Cleanup.\n◦ Method 3: If a Low Disk Space notification appears, click the notification to open the Disk Cleanup wizard.\n\n\n2. Select the Windows 7 system drive, and then click OK.\nNote: This operation might take several seconds because the Disk Cleanup wizard searches for files on the drive that can be cleaned up.\n\n3. 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.\nNote The Windows Update Cleanup option is available only when you log on by using administrator permissions.\n\n4. Select the Windows 7 system drive, and then click OK.\n\n5. On the Disk Cleanup tab, select Windows Update Cleanup, and then click OK.\nNote By default, the Windows Update Cleanup option is already selected.\n\n6. When a dialog box appears, click Delete Files.\n\n\nNotes\n\nThe Disk Cleanup wizard runs in the background.\nYou may have to restart the computer to finish the cleanup process.\n\n\nFor more information about how to use a command line to configure the Disk Cleanup wizard to automatically clean up certain files, click the following article number to view the article in the Microsoft Knowledge Base: \n315246 (How to Automate the Disk Cleanup Tool in Windows XP and Windows 7 ) \n \n\n \n\nUpdate is available that enables you to delete outdated Windows updates by using a new option in the Disk Cleanup wizard in Windows 7 SP1\n\nPrerequisites: Windows 7 SP1 !\nTo apply this hotfix, you must be running Windows 7 Service Pack 1 (SP1).
