Deleting $NtUninstallKB$ and KB Files

Tags:

On my Windows file in XL I have approx 80 of $NtUninstall KB files and42 KB files. I am using Reimage application to update the computer. When it finishes a check it advise me that it has to apply the  windows KB files. That is the 42 files I have which it then proceeds to download and install these files current on the computer. Some of these files (if not all) are included in the 80 odd $NtUninstall etc files. What use are they? Can I delete them? Or can I store them say on a USB. Though I have plenty of space on my C drive I am still having some slow down which I presume is due to the memory. Can you help me? Ted Arrowsmith

Thanks. We'll let you know when a new response is added.

Those are not files, but directories that are created when a Windows update or patch is applied to your machine.  They contain the information necessary to uninstall those patches in case you want to do that for any reason.

The probability that you need to uninstall a very old patch is very small, so you could safely delete the oldest ones (more than 3 months old, for example).

The option to copy them to a USB drive or CD/DVD is also a good idea.  You could move all of them, and only copy them back in case you need to install some update or patch.
