Frequently Asked Questions

Is the 8.63 GB in Disk Cleanup actually wasting my drive space?

No! Microsoft and community audits confirm this is a display reporting error in the legacy Disk Cleanup tool. The 8.63 GB does not actively steal disk space. Do NOT attempt forceful command-line deletions on CBS/WinSxS, as that can permanently brick future Windows Updates.
