Please help with vmware workstation.

Okay i downloaded and installed vmware workstation. But i can figure out how to get a os on it like windows xp or professional. I dont have a cd or iso. CAn u guys please give me link to one if thats how u do it.

I had it too, and I've installed Windows XP with original CD, that's the only way I know. Windows takes a lot of space so... I don't think there is a crack or something.... you have to install it. OR... if you have Windows7, install XP Mode, it's free if i'm not wrong.
