By Default in Windows 7, UAC is turned on to notify you when some programs try to make changes to your Computer. If you try to run any program, UAC pops up and asks for your permission, this is a bit annoying, that’s why users’ disable UAC or set it to ‘do not notify’ level, but this is not recommended for any user.

If you’ve UAC turned on, just like to any other application you’ll get a UAC warning for CCleaner also, just like as other program, good news for you, Piriform has added “Skip Users Account Control Warning” to its Cleaner tool Advanced Settings, which you can enable and skip this dialog for faster booting or startup of CCleaner.
