Many WinSXS folders of C:\windows under Vista have reached 5-8GB, which will greatly reduce the system disk space.

You can use the tool Vsp 1cln.exe to uninstall the files archived after applying Windows Vista SP 1. When installing Windows Vista SP 1, the disk space used by the operating system will increase. This extra disk space is used to archive files so that Windows Vista SP 1 can be uninstalled if necessary. Generally, if you want to reclaim this disk space after applying Windows Vista SP 1, you should run the Vsp 1cln.exe tool, but only after you decide not to uninstall this service pack.
