blzh left his Windows 7 laptop unattended in the cafe!
You don't know his lockscreen password, you only have 15 minutes until he's back from the bathroom, and you desperately need the flag on his desktop!
Go to the blzhquest stand and try breaking into blzh's laptop. You will have 15 minutes. Attempts are unlimited, but you'll have to wait in queue.
You can only use keyboard, mouse and reset button. You can't boot from USB or CD. blzh has just a vanilla Windows 7.
