Unable to optimize the Windowsdirectory (Booster)
I use Booster as a member of a testgroup in Sweden and after the testperiod i will leave a rating of Booster. I have Windows 10. My question in english: When I select Clean my Booster always stops with this message "Unable to optimize the Windowsdirectory right now. System restart required." I have restarted my computer 5-6 times with the same result. What is the problem with my Booster? Everything else works.
