It hangs, unable to clean beyond 12%. also unable to cancel/stop. ( pic attached) note; this is not the first time, I am posting this after using much attempts.
system: DESKTOP PC : HOME: WINDOWS 10 PROFESSIONAL: BROSWER: EDGE + CHROME iNTERNET : >10MbPS
I note that it's stuck on Internet Explorer History, which has been an ongoing problem for a while now with the time it takes, and some hangs like yours.
As you don't seem to be using Internet Explorer then you can safely uncheck all the options for it - except for 'Temporary Internet Files' which is used by other MS applications.
Hopefully that will cure your problem as it has for others.
