How to save windows games

Some windows games such as Gears of war demand that you have a profile to save the game

There are two possible profiles you can create
1. Local profile
2. Online profile

If you want to just play the game locally and not get into entering game serials/ playing online. The easiest way is to create a local profile

Just click create a local profile link on the page shown by Games for windows marketplace client during game play. (usually Second page on creating profile)

Tried it on Gears of War

Happy gaming! :)
