I installed SP3 for XP the other day (using IE, which I never use for anything else, to run Windows Update). After doing so, I tried to go to Tools->Internet Options to clear cookies, etc. and got an authorization error saying I was not authorized to do so. Even though I am the sole user profile and administrator of this computer. WTF? Is MS now deciding they have the right to lock me out of parts of my own computer (I admit I did not read all the legal stuff in detail), or is this an error? Anyone else have this issue? I can Explore to the Temporary Internet Files folder, etc. and manually delete the files, but I am concerned with having authorizations messed with by MS, here and potentially in other places on MY computer that I just haven't noticed yet. Anyone else have authorization issues after installing SP3??
