This tip is for those who had installed SP 1 but have not yet installed SP 2. After installing SP 1 on Windows Vista, one will be able to uninstall it at a later stage. However, for this to be the case, Windows will create a backup which eats up considerable disk space. If one is sure that an uninstall of SP 1 will never be needed, a command prompt can be opened and the following command typed: vsp1cln.exe . Following that it is just a matter of waiting until the backup is deleted. It has to be noted that upon completion one will not be able to remove SP 1 from the system.
