$ntuninstall folders

wanted to free up space on one of our server's c drive and noticed in windows directory that there were a lot of folders called $ntuninstall and was wondering if i could delete these.  I seem to remember that these were related to upgrades for microsoft and if i could delete these safely would be able to regain some space on c drive.  thanks

If you were to remove these, space would free-up. However, if you were to uninstall an errant update, these folders are what Windows would you to try and roll-back it's previous state. As long as you have regular and validated back-ups, I don't see why these folder could not be removed.

You can delete those folders if everything is working OK.  I also delete them after some time (after the Updates install) and I feel that there would be no need to uninstall any update.

Normally, to be safer (my opinion) I will delete the older ones (using the folder date) and keep the ones which are about 1 month old.  Then later (when cleanup time is required) I will delete those and keep any new ones.
