i am running the latest version of ccleaner, build 1.35.424, and, unlike all of the previous versions of ccleaner that i have used, it will not remove the MS updates uninstaller files and folders, the files that are using for uninstalling MS updates..
i uninstalled CCleaner build 1.35.424 and installed the older build 1.34.407 and build 1.34.407 removed the MS updates uninstaller files..
It's a bug in 1.35. It will be fixed in the next version.
