Ucheck reported it found an updated version with version number 3.4.0.101. I played with the download link of the CIS cleanup tool and found the 32 and 64 bits versions of this new version. Both files are signed with a valid signature.
These versions are not officially released so treat them as beta software. Use at your own risk and only recommended for the curious, adventurous and experienced:
