Local admin
Maybe it's just that I appreciated what Jesper & Steve keep talking about...
A while back I ran through various things on my machine to try to encourage it to be slightly more secure. I know I didn't do everything I could've done, but I did some. Today I tried to run something (not something I wrote, something someone else wrote) and I got a nasty error. Tracked it down to the fact that Performance Counters were disabled. But as well as that, I wasn't running as a local administrator, which it seems I needed to be to allow access to said Performance Counters, all so that the system could detect if they were already running a copy of the app in question. I don't like having to be a local administrator. I don't let my kids run their computers as local administrators, and I would really rather not be one myself. Even more so, I don't want the people running my applications to have to be local administrator, and I try to make a point of not requiring it. Mind you, just about everyone I know runs under local admin, and I guess it's 'normal' to do so. I just don't like it. I guess I'm 'different'. Thanks, Jesper & Steve.
I'm looking forward to being able to escalate privilege as required.
