I'm trying to find out if there are any parameters that will let you run Produkey.exe and only get the Windows Version Key.
As it stands, the script I'm aware of creates two lines in my file, one for the Windows Installation Key that includes the machine name, the other is the BIOS key.
ProduKey.exe /IEKeys 0 /OfficeKeys 0 /WindowsKeys 1 /scomma >> export.txt
The only other thing I can think of is to sort by a column I know the bios key doesn't normally fill, then I can ignore the rest of the data.
