Delelte NTUninstall folders in windows folder?

Do you have the $NTUninstall folders in windows folder? Can they be deleted?


These $NTUninstall folders are created when you install a Microsoft Service Pack, a hotfix, or certain security updates. These folders contain the uninstall information for the update you install. That means, you will be unable to remove an update in future, if you delete these folders. You may leave them there unless you need hard drive space. Each Qxxxxxx represents an update from Microsoft. To know more about an update, type the URL in your browser:
http://support.microsoft.com/?kbid=xxxxxx
Replace the xxxxxx with the actual numbers. Don't use the prefixes Q or KB
You will also see the corresponding Uninstall entries in Add/Remove Programs list. To manually remove the hotfix entries from Add/Remove Programs, try this:
Start Registry Editor and locate the following key:
HKEY_LOCAL_MACHINE \ Software\ Microsoft\ Windows \ CurrentVersion \ Uninstall
Backup the key by exporting to a file
Look for the hotfix number in the sub-keys
Delete the entire listing for the hotfix.
Close Regedit
By doing the above, only the Add/Remove entry is removed; the update will not be removed.
