Reminds me of when the PCs on display at Sears, CompUSA, etc. would have their demo software running which didn't let you do the one thing you should do when buying a PC.. actually use it. So I used to CTRL+ALT+DEL and kill the demo software with the task manager. For the more stubborn demo software that would instantly relaunch, I'd then open msconfig, uncheck the demo software from running on startup, and reboot.
I remember the amazement and joy of other people nearby watching, who would then ask me to do it on their PC so they too could click around and play Minesweeper or Pinball :-)
Sounds so amateur now, but it's hard to remember that CTRL+ALT+DEL in the mid-90's was -- dare I say it? -- sort of a power tool that only more experienced users knew about.
