I do not have Windows 8 instruction, however while this MAY apply to Windows 10 these instructions are for my Windows 11 OS
Create a new text document
Type " Taskkill /IM msedge.exe /F " without "'s (please see attached image)
Save document as .BAT (old school batch file ex., new text document.bat)
Run document as Administrator
Run cCleaner
There may very well be an easier way but this works for me.
Thanks and hope this helps.
