By Default starting from Windows 7 to Windows 11, User Account Control (UAC) is enabled and notifies you when you run some programs on your computer. If you launch any application, the UAC dialog pops up and asks for your permission, this is a bit annoying, that’s why users disable UAC or set it to the ‘Never notify’ level, but this is not recommended for any user from a security perspective.
If you’ve UAC turned on, just like with any other application, you’ll get a UAC warning for CCleaner also when you open it.
But, Piriform has added “Skip Users Account Control Warning” to its Cleaner tool Advanced Settings and enabled it by default in the Application for faster booting or startup of CCleaner.
The UAC skip feature is built into CCleaner in version 3.19 and here is its changelog. The update adds support for Firefox 13 Beta and cleaning capabilities for other apps, and as usual, this release contains minor bug fixes and other improvements.
Enable or disable the Skip UAC Warning option in CCleaner
1. Open CCleaner
2. Click on Options and Select Advanced
3. Ensure “Skip User Account Control Warning” is enabled or the checkbox is ticked.
4. Exit from CCleaner, and re-run the app, and you won’t get the UAC dialog this time. This helps CCleaner to load much faster as it avoids the UAC dialog users had to click on.
If you want Windows to show a UAC warning when you open or run CCleaner, untick the option mentioned in the third step.
