I’m looking to buy a Dell Precision T1700 SFF with Windows 7pro. I browsed ebay and found a few, but some come with Windows 8 pro. Now it is my understanding that all windows pro Versions come with downgrade rights. After entering a few service tags in the Dell OS Recovery tool I found that some allow me to download both Windows 7 and Windows 8 but the Item I’m interested in would only let me download Windows 8. Also the iso filename of the Windows 7 that is downloable with some of the Service tags is different from the “usual” 7.06 GB file.
