Every Windows 8.1 installation I had eventually resulted in me having permissions problems because many programs I use and install must be executed "As Administrator". I also use "Take Ownership" for many game folders, but never entire Program Files or Windows folders. I also use JV16 PowerTools 2014 and use the experimental and super-thorough level of registry cleaning, which may also mess things up. Its always permissions... Maybe I should just switch to using pure Administrator account in Windows 8.1. I am talking the one that blocks all Windows Store apps and disabled UAC all the way. Using such an account would prevent me from having to run anything "As Administrator" as it would happy by default. I did hear that using that account can lead to problems. Is that true? Is there any reason I should NOT use it? Will it work fine with my activation? I have a legit product key! How do I access that account? EDIT: I just ran "net user administrator /active:yes" in CMD and restarted. However, I did not get the choice to login as Administrator upon booting/logging-in. Why is that? I want to get to the pure Administrator Account and use ONLY it. Then I want to remove current user-administrator account. I hope that would fix all the permissions issue once and for all!
