Hi all: Until I begin our final roll out of Win7 I will have to deal with individual OES keys or MAK until we have enough clients for KMS to take over. I really don't want to use the MAK keys during testing as I am afraid I will run out of keys as I re-image our test computers. I don't have experience using MAK keys so this may not be a problem but I don't know.

So I was wondering if I could use HPs BOISConfigUtility.exe to read the serial number, and then use the serial number to match the OEM key to that machine and register with MS (either case statement or a bunch of if statements)? Has anyone done something similar?

Thanks, Chris.
