Yes, you can install Microsoft Windows XP~~
I reinstall the Microsoft Windows XP Professional when I am on the way home on New York Subway (F Train).
It took me 30 minutes to reinstall the OS and another 20 minutes for the drivers(when I was on Path to NJ).
Maybe you can get some cases to earn more money when you are on your way home.
After all, Time is money, my friends (Said from Goblin, WOW)
