Windows 7 - Upgrade from vista to W7

I've got windows 7 EC 7100,which is Windows 7 Ultimate.What I would like to know is how much it's going to cost me for the upgrade.My origanal os was vista basic,I started with Windows 7 beta when it first came out.So I do have a product key.

Have you asked a retailer?

A upgrade form vista to windows 7 Ultimate would cost 220.00 $ at Best Buy

NewEgg $ 199+ if you want Ultimate

Newegg.com - Operating Systems, Microsoft Windows 7, Win 7 Ultimate, Win 7 Pro, Win 7 Premium, Windows Vista, Microsoft Windows XP, Win 7 Upgrade.

The RC is not the finished product, is still buggy and has a ton of monitoring software taken off in the RTM. There is a blog post from a Windows 7 developer sticky'd on Technet Install forum begging users not to upgrade it. Some have, though.

That said you can still affordably achieve it with this fix: UNAWAVE - Downgrade Ultimate to Home Premium or Professional

Note the extra caveat at the bottom for using the RC.

Your best bet for Up/downgrading is the $150 family 3 pack of Premium upgrades, less than half price each which is the best deal offered yet. You can have it on 3 machines of your choice for life.

upgrading to windows 7 can be expensive.

I'm sure the same can be said when upgrading to a lot of things.

To run free for awhile, try the Windows 7 Enterprise 90-day trial downloadable from MS.
