hi all,
i have around 10 Dell OPT 3020MT PC's with dell win 8.1 pro license. due to software compatibility issue i have downgrade all these PC's to win 7 pro using dell win 7 pro OEM DVD. every thing works well until microsoft has done audit in my company and found out that all the downgraded PC's contain 32KD2-K9CTF-M3DJT-4J3WC-733WD key which came with dell installation media. so now microsoft claim that is this not legal. so i want to know what will be the Legal procedure to downgrade PC's with Windows 8.1 pro to Windows 7 Pro in multiple PC's?
