Hi Al,
The following information is from an early post:
"...we've checked every angle and possibilty, from getting XP Professional and then using Software Assurance to upgrade to Win 7, to getting Vista Business and using Software Assurance to get Win 7.
Unfortunately there are NO legal upgrade options to go from Vista Home to one of the upgrade products that are offered through TechSoup. This is because the Microsoft products carried by TechSoup are Volume Licensing products which have different licensing restrictions from commercial products. I don't know if you can get a retail Vista Pro upgrade product and use that to upgrade - I'm not familiar with the commercial products' licensing rules - but that might be a possibility.
For orgs that want to break the cycle (from the Microsoft Home line to the Business/Pro line) you'll need to either get a new pc with a professional license, or buy an OEM license and pay a little less. So if you pay $150 for an OEM Vista Business license, you can get a donation of Windows 7 Pro upgrade for $8, then you are still better off than buying retail, and you get Software Assurance benefits too."
Please let us know if you have any other questions.
