clean %windir%\$NTUninstall* folders

Recommended Posts

I read on the recent WindowsSecrets newsletter:


"Take out the trash ? all of it. Needless file clutter makes a system harder to use and slower to operate. For example, AV scans and Windows' indexing both take longer when they have many junk files to process.


Start by deleting old $NtUninstall{xxx}$ files from XP's C:\Windows folder; these files can occupy a shocking amount of space! You need these files only when a Windows Update fails and you (or the OS) have to roll back your system. If your system is working fine, $NtUninstall files serve no purpose."


So far I have in my winsys2.ini:


[Empty WU Rollbacks]







Is this correct? I'd like to remove the contents of each folder and the folder itself - just not sure if CCleaner will handfe multi/unknown folder names correctly?


the quote about needing the files if an update goes wrong brings about another question. Is it possible to do a custom warning message like there is already for Windows > Advanced settings for CCleaner?


thank you in advance

Problem is not all of those folders are completely safe to remove.

other than on XP microsoft does not want you to delete Windows update folders, it needs them when it reupdates those files,


as was stated by Andavari above.
