to whom concern
I worked @ IT department in company , i recived recentely 100 HP Prodesk 600 G1 PCs , and all of them come with built in license for windows 7 Pro and eligable to upgrade to windows 8.1 Pro . the question is I have microsoft system center product called SCCM ( system center configuration manager ) and I would like to deploy the OS through it , how i can make sure that lisence will work with no issue , should I take an image from recovery CD that came with devices or there is any another way to deploy through SCCM .
note that : each device have CD for windows 8.1 OEM but no lisence label
please your advise .
regards
AJ
