Renaming executables to explorer.exe worked with the application whitelisting solution my school implemented.

That's how we ended up with 8-player age of empires 2 deathmatches after hours ;)

I created a directory with alt+255. It was an unprintable character and showed up last in any dir listing. At most it added an extra new line. That’s how I was one of the only students whose apps didn’t get caught during auditing.

That brings me back. All .exe were blocked.

However it turned out that you could rename them .bat or .cmd and they would execute just fine.

I think Doom 2 multiplayer was extra fun because of the added need to be aware not just of in-game enemies but also the need to be aware of the teacher and be ready to instantly quit at any moment.

Haha, me too :D

Wrote a batch script that used a wildcard - it took them a while to find it and I was very lucky the only 3 persons who knew who it was wouldn't tell anyone. One was a teacher and I am thankful until today that he didn't screw up my life with telling this.
