Using vsp1cln.exe to clean up your hard drive after installing Windows Vista SP1

The Windows Vista Service Pack 1 (SP1) Files Removal Tool (VSP1CLN.exe) can be used to remove the files that are archived after Windows Vista SP1 is applied. Running this tool is optional.

Installing Windows Vista SP1 increases the amount of disk space that is used by the operating system. This space is used to archive files so that SP1 can be uninstalled. Typically, you should run VSP1CLN.exe if you want to reclaim this disk space after applying SP1 and if you will not need to uninstall SP1.

You cannot uninstall Windows Vista SP1 after you run this tool.

To run the Removal Tool from a Windows command prompt, simply type vsp1cln.exe and wait a minute or two.  If you require verbose output, run

vsp1cln.exe /verbose

If you’re receiving The parameter is incorrect error message while running vsp1cln.exe, see KB 949472

    I have installed sp2 over sp1 on two Vista Business machines and cannot get vsp1cln.exe to work under run or command. Any ideas please or to remove old files manually? All admin rights set.

    In Vista SP2, you need to run compcln.exe in place of vsp1cln.exe.
