I have over 60 "$NTuninstall" files.
Can they be deleted?
As someone else has said, these are the "uninstall" files for Microsoft
updates. After an update I usually hold onto the uninstall folder for about
a week or so and if there don't seem to be any serious problems I then
delete it. After deleting the folder, you probably should also go into the
Control Panel > Add/remove programs and get rid of the entry for it there.
(Don't worry, the warning you get is not a dire as it sounds.)
Even if a problem with the update does subsequently arise, you can usually
recover from it by reverting to the restore point that the update makes
before installing itself.
