I fully agree with Redhawk's last remark!
Moreover if you try the solution given by moderator Twistedmetal, ("[solution] Registry Issues Keep Re-appearing In CCleaner"), going to the site of Dial-a-fix, will serious warn you with the following:
"Dial-a-fix does not work with any Windows OS higher than Windows XP. This includes Windows Vista, Windows 7.
Dial-a-fix also has a critical unpatched bug that will delete your C:\Documents folder."
So, until CCleaner has been fixed in a proper way I will not use it on my Win7 64bits system!
