Windows 7 trial upgrade

I have Vista. I am on disability and cannot afford to purchase the windows 7 operating system. I do not have a business. Can I get a free trial of windows 7 for my persoanl home computer and where do I find such a trial ?

marcellis is right. You're going to have to buy it no matter what. There was at one time a 90 day trial of Windows 7 Enterprise, but I don't think it is available anymore. Your cheapest option is going to be an OEM copy, which is roughly half the price of a retail version.

Actually, any copy of Windows 7 can be installed without a license key and it will work for 30 days. You can "refresh" it up to 3 times to get a total of 120 days out of it before it will quit working (it was 120 days with XP, I haven't actually tried it with Win7 and it might only be 90 days).

That's fine for a trial, but you will eventually have to buy a valid copy.

You are correct, however the legality of obtaining the disk (See the label on all the official media stating "Do not make illegal copies of this disk" ) would be an issue, given that the Windows 7 Enterprise trial is no longer available (if anyone knows otherwise, please feel free to say something).

Edit: For clarification, I meant that the legal issue comes into play when you obtain the disk by copying it from a friend, regardless of whether your friend shares his/her serial with you.
