Deleting $NtUninstall Folders from Windows directory

Question

Can I safely delete old (i.e. 6 months or more) $NtUninstall folders from the Windows directory of my XP box?

EDIT: thanks for the feedback everyone - does this also apply to the stuff in C:\WINDOWS\Installer?

EDIT 2: OK, have found the answer (the answer appears to be "no") to the windows installer issue here:

Answer 1

Those folders are associated with updates from Microsoft. If you delete them, you won't be able to uninstall the updates regularly, which you probably don't want to uninstall them anyways for security reasons!

So the bottom line is, if you don't plan on deleting the updates, it's safe to delete the folders.
