Yup

Giving wise cleaner a shot.

I guess they have owned them for over a year already... 

Avast now owns CCleaner after acquiring Piriform

Oops...

https://www.ccleaner.com/download

When I had CCleaner open before I upgraded I clicked on check for updates on the bottom right. That took me to, blankety blank...CNET, not piriform's website. SOB! Version 5.45 seems to me to be somebody's addition to 5.44. Data mining perhaps, by Avast A/V perhaps. The anti spy spy. Lol

I did dl wise cleaner and installed it after uninstalling CCleaner. It did a deeper clean than CCleaner, taking out 1.6 gigs of totally useless junk. It cleaned out WinSxS where CCleaner didn't. That accounted for most of it. Only thing is when I used CCleaner it cleaned out all of my browser history so I had to log in at WC. Didn't happen this time, I was still logged in. Haven't checked other sites I go to yet.

Downgrade it to whatever version (afterdawn.com or filehippo should have older versions) then install ccenhancer or do what neophil said or just stay of the web

Thanks for that tip!!! I just installed it and kicked the tires. Seems to do as expected but have not noticed any real performance gains.

Swapped out CC for GU here as well.  I had used GU a number of years ago, not sure why I abandoned it then.  Seems to do everything CC (free) could do.

May give WiseCleaner a spin, too.

I did notice one thing. Boot up time went from 42 seconds to 21 seconds. Cut it in half after running Wise Cleaner.

I use CC Cleaner but its 5.00.

When I started my computer this morning I got a message saying that CCleaner could not run in my location!!!!

Check which version you have. That happened to me with version 5.45. The actual update version is 5.44 at the piriform website. The version I had came from CNET.

I have version 5.45. It works OK now.

Me too. I've never had a problem with CC Cleaner
