Back in middle-school; the public library nearby installed 4-5 new machines down on a lower level for word-processing (they were better than my home pc even), so pretty soon we had Unreal Tournament installed on every machine, and that would be our goto spot after school.

Once in a while someone would get banned from the library for a couple weeks (I think other kids that saw us started playing as well, so it was hard for them to identify a culprit), they would call in IT, overhaul their computers and we'd be back to laning a month later once things cooled off.

Do you think privilege escalation is unusual on Windows now, then? :)
