Closed all apps; ran a CCleaner registry scan; result: 12 issues. Fixed 12 of 12 issues. IMMEDIATELY ran another registry scan (did not open any other app); result: 6 errors. Fixed 6 of 6 errors, IMMEDIATELY ran a third registry scan; result: 2 errors. Fixed 2 of 2 errors. Fourth scan; 2 errors. WTF?
Well, who knows what Windows is doing, or what regstry permissions apply, or what errors are appearing. It isn't the end of the world to run the registry cleaner a few times.
By the way you won't last too long here if you continue with your WTFs.
what is your OS?
if Win10, it's a continuing evolving beast, with major changes at least twice a year.
how software developers are keeping abreast of these changes must be a logistical nightmare, particularly concerning the inner working of the Registry.
the web is awash with expert advice these days that basically say reg cleaning is a waste of time, MS themselves have officially come out toting the some mantra.
