I have Windows 7 Professional PCs (mixture of 32bit and 64bit, but mostly 32bit PCs) and I need to upgrade to Windows 7 Ultimate to use "BitLocker" function.
That said, I see a lot of internet vendors selling "License only download link".
Here is an example but there are quite a few out there.
Of course that are significantly cheaper than Full Retail version or Retail Upgrade version.
But since I am not familiar with these types, I want to educate myself before trying it.
What are the pros and cons?
