Windows Update Cleanup Saves Huge Disk Space in Your Root Drive | Next of Windows
The update only works on Windows 7 with service pack 1 and above, meaning that in order to take great advantage of this new update, you will need to install service pack 1 on Windows 7 systems, if you haven’t done so. One thing you need to be aware of is that once you run Disk Cleanup wizard to have all windows update cleaned up, you won’t be able to roll back to a superseded update.
