After Installing SP1 For Vista, Old Files Remain

I received an email last evening referencing the fact that after installing SP1 for Windows Vista, the old files remained. The writer also wanted to know what would happen if the old files were removed. The only thing that will happen is that you will be unable to uninstall SP1 at a later date.

All you need to do is go to the prompt and type in : vsp1cln.exe This will run the auto clean feature and dump the old files for Vista pre SP1.

Oh, by the way. There is some confusion in some of the terms that Microsoft uses to describe updates, hotfix, service packs and the like. Microsoft has provided an explanation of what they are talking about here.

Also, if you have not received an automatic update notice for your copy of Windows Vista to update to SP1, Microsoft has posted a list of reason why your system may not be ready yet for SP1 located here.

Comments welcome.

    Does something like this exist for Windows XP SP3? I recently installed it as an upgrade in a VM and the VM file grew like 2.5GB or so. I’d like to make it smaller if at all possible. I could always just delete the restore point but figured I’d ask since Windows Vista SP1 has one. I did a couple of Google searches using:


    Nothing came up.
