My company is planning to buy windows 7 ultimate for the server that we use. I cautioned my boss, since I think there is a limit on how many computer can be connected to it (it was 10 for XP). But my boss think it should not be a problem since he is buying the ultimate version. Who is right on this?

I have A student version of windows 7 professional. I installed Windows 7 student version on my desktop but I also need it on my laptop for school. May I install it on my laptop now or do I have to purchase another disk. I am only allowed to purchase one disk as a student though.

We just got a new laptop and we would like to install our widows xp to it. We have installed it on two other home computers. Can we use it again?

After building my own pc and installing xp home on it without a license, I am looking to buy upgrade to xp pro before the license free period of the home edition of 30 days is up.

I was just wondering if I purchased an upgrade version of xp pro, how many computers would I be able to install xp pro on without buying any additional licenses?
