Free Up Hard Disk Space After Installing Windows Vista Service Pack 2

After installing Windows Vista Service Pack 2, you can use the Windows Component Clean Tool (COMPCLN.exe) to remove the archived files. This tool also removes the files that were archived after Windows Vista SP1 was applied. You can free up more than 1 GB of disk space (if the Vista SP1 Files Removal Tool VSP1CLN.EXE was not already used.) When COMPCLN.EXE was run in a system in which VSP1CLN.EXE was already run, it freed up 440 MB of disk space approximately.

You may use this tool if:

The PC (running Vista SP2) is stable, and you do not plan to remove SP1 or SP2 in future.
Your hard disk is seriously running out of space.

Note: You’ll be unable to uninstall Windows Vista SP1 or SP2 after running this tool.
