Does anyone know how to create a Windows 7 Ultimate 64-bit OEM disk for SLIC 2.1 activation? Is the process the same as for Vista?
yes the process is the same as vista apart from vista uses pid.txt for serial and 7 uses autounattend.xml or a command file.
or you could use DISM to integrate your CERT + KEY directly into your install.wim (along with Drivers + Updates)
