i too had this bug on 2 different machines (maybe more i don't remember), after upgrading them on creator's update 1703.
In place upgrade save me twice to correct this.
On both machines the last ccleaner was installed (old one couldn't run), i think 5.30 and 5.31.
The Windows.old folder takes too much place, i realy would like to remove it.
I didn't try with ccleanr 5.32, is it fixed now? And is it working well with windows cleaner tool?
Thanks for answers, have a great day!
By the way i realy like your tool!
