Question 2

how many window 7 professional upgrades do you have for sale.

Accepted Answer

Thank you - Will this upgrade work for Windows XP?  Do you give any discount for multiple purchases (we would need 10)?

Question 3

will this work on multiple PCs (that all have valid licenses) or will i have to buy one for each PC to be upgraded? thanks

Accepted Answer

Technically, yes, you need one for each pc though, historically, Microsoft has allowed you to install it on a desktop and a laptop without issue.

Question 4

Is this a retail copy

Accepted Answer

This is the product that Microsoft generates for Windows 7 Professional version.  You can get the same thing from Microsoft.  It has worked on my machines as advertised.  Retail copy is a good question.  Most things are being sold by third parties because they have extra copies or they have moved on to Windows 8.  These products are what they say they are and work exactly like what Microsoft has intended them to work.  In other words there is NO WAY that the third-party provider can change the Microsoft product.  On your end, your target machine must support what Microsoft has defined for hardware definition required, like AERO Support.  Older computers must be brought up-to-date technology.
