Steps:
1) Change user temp variable, say 'B:\Documents and Settings\GenaU\Local Settings\Test'
2) Open CMD window and run 'BroadcastEnvChange.exe /broadcast broadcastsystemmessage'
3) Run 'BroadcastEnvChange.exe /broadcast sendmessagetimeout'
3) Open new CMD window and type 'echo %temp% -- you'll see long path
4) Change user temp variable back to 'B:\Documents and Settings\GenaU\Local Settings\Temp'
5) Return to first CMD window and run 'BroadcastEnvChange.exe /broadcast sendmessagetimeout'
6) Run 'BroadcastEnvChange.exe /broadcast broadcastsystemmessage'
7) Open new CMD window and type 'echo %temp% -- you'll see short path
Hopefully!
