CCleaner Not Responding, access denied when trying to close

I have a hanging faded CCleaner Browser window open I cannot close.

C:\Users\operation420.net>taskkill /f /im CCleanerBrowser.exe

ERROR: The process "CCleanerBrowser.exe" with PID 20364 could not be terminated.


Reason: Access is denied.


ERROR: The process "CCleanerBrowser.exe" with PID 17844 could not be terminated.


Reason: Access is denied.

... more left out

I have tried command line as Admin, Trusted Installer (using advanced runas), and Process Explorer and cannot get rid of all these hanging processes!!!

Are you using Win 10 ?

Does a full RESTART of your machine not do it? (not shutdown.. select RESTART instead)
