Use the Windows Component Clean Tool (COMPCLN) Uninstalling applications does not immediately free space in the WinSxS directory space for unused assemblies is garbage-collected over time by the Installer service. By default not even administrators can modify its contents (without taking ownership first). This allows updates to be uninstalled safely.īecause of its elevated importance, from Vista onward the WinSxS directory is owned by the Trusted Installer service SID. For example, after installing some Windows updates, old file versions replaced by the updates are still kept in WinSxS although they are no longer linked in the "live" Windows directories. However, not all files from WinSxS are projected this way to "live" operating system files. Windows Explorer double-counts the disk space occupied by these files. This can be demonstrated using the fsutil command-line program.Some third-party Explorer extensions to show the link count also exist. the System32 directory and application directories). A file in a directory in WinSxS may be linked from multiple locations (e.g. Operating system files in the WinSxS directory are linked to from their usual locations in the Windows directory structure. From Vista onward, the operating system also uses WinSxS for its core components.
