[CCleaner4.11 issue = Shuts down computer]

 

You may also want to look in your Windows Event Log by opening Event viewer , hopefully it will have logged any issues/errors.

 

And just to make sure:

1. Open CCleaner from Start->Run and manually have it load CCleaner.exe (don't use a shortcut).

 

2. Go into Options->Advanced and make sure this box is not ticked: Shutdown after cleaning

 

3. Close CCleaner, then right click and select Properties for any CCleaner shortcuts you have on the Desktop, Start Menu, etc., and make sure the Target doesn't have any parameters listed after CCleaner.exe, in particular make sure it doesn't have /AUTO /SHUTDOWN listed in it:

 

Example 1 (CCleaner runs normally with manual user interaction):

"C:\Program Files\CCleaner\CCleaner.exe"

 

Example 2 (CCleaner runs automatically without any user interaction, and will automatically shutdown/turn off the computer when finished):

"C:\Program Files\CCleaner\CCleaner.exe" /AUTO /SHUTDOWN

1. Open CCleaner from Start->Run and manually have it load CCleaner.exe (don't use a shortcut).

2. Go into Options->Advanced and make sure this box is not ticked: Shutdown after cleaning

I was having the same problem, did the first two you suggested and yeahhhhh!! No more problems. Thank you and have a great New Year.
