Good evening.. Was do some looking around trying to set my access to files and security back to default....Discovered that these S1 user files that are being set up are aquiering trusted installer privledge..Then if you go to the security tab on a file that they have control of you will just see system and everybody ..Also listed both with full controll, or administrater will still be there but only with full control cannot get trusted installer privledge..Also see the windows has sent a bulliten out saying to disable desktop apps.. I also see theyy have made a bunch of changes in recycle bins...In my logs there were a lot of problems with the apps..So my question is setting everything back to default or owner is not really going to help
