Okay so I'm going on a business trip, and the company says they don't want me using my own laptop and gives me some crummy laptop from storage. They say I can do what I want to it, because when they get it back they're just going to wipe it. I have the misfortune of the OS they keep wiping it with being Windows Vista. In the short time I've had it I've already run into several annoying problems that's got me missing Windows 7. My routes thus far have been trying to convince them to invest in Win7, to which they've responded "we're not spending any more money on that machine". So I thought about going down the dark alley route and just getting a Win7 disc from my own PC and installing it with that, since they were going to be wiping it anyway if it cause bugs later on no big deal. However again, the company said I am their representative and that was essentially pirated software on a company machine, and it's a big no-no. So I'm trying to figure out my options, I know they used to run a 90 trial of Win7 but that's long gone. I just need this computer to work for 30 days, is their any option that can legally get me upgraded from Vista to Win7 for that long? If it's a trial or tester and runs out after that period I don't care. Any ideas are welcome, thanks!

Oh wow I thought that was over! So I can just download this and upgrade my Vista to Enterprise free for 90 days?

You need to read ALL the fine print on the referenced page. I don't think you can upgrade any version of either Vista or Win 7 with the Windows 7 Enterprise 90-day trial. Also, the Win 7 Enterprise must be completely removed from your system when it expires.Please remember to click Mark as Answer on the post that helps you, and to click Unmark as Answer if a marked post does not actually answer your question.

You would need to create a Windows 7 installation DVD (see the FAQ section) and while at the Windows Vista desktop, insert the DVD in the drive and select "upgrade". Please note that the existing Windows Vista installation must have either SP1 or SP2 installed. Carey Frisch
