Windows Update uninstall files
Posted by Tyngman on November 27th, 2003


I am running low on disk space on my boot drive. I was
wondering if after windows does the updates and is proven
to run fine, can you delete the uninstall files? I can
gain almost 2gig of space if i remove the uninstall files
on a 4 gig boot drive.

Hi

Yes, you can safely delete all $NtUninstallQxxxxxx$ folders under your windows
folder, where xxxxxx is the different patch numbers. If you have a folder
$NtServicePackUninstall$, you can delete that one as well if you don't want to
be able to roll-back the SP.

You should *not* remove the %windir%\servicepackfiles\i386 folder if you have
one.


Here is a script that can help you (works for Win2k/WinXP, I think it should
work for NT4 as well):

Remove Hotfix Backup files and the Add/Remove Programs Registry entries

Note: Doug's program only removes the uninstall files and Hotfix
entries in the Add/Remove Programs listing. It does not remove the
actual updates.
