Who is "TrustedInstaller" and why do they seem to have more control over my computer then me?
I have been removing some files to clear some space and found that despite being the Admin I am unable to delete them because they are from "TrustedInstaller". When I go into security settings it wont let me change anything to do with it and I can't remove
it. I find this incredibly frustrating as I own this computer and expect to be able to control what goes on it.
