Basically correct. It's easy - basically two little things one must do - a
regedit and a commandline command.
Install Windows clean with the upgrade disc but during the install routine
do not type in the 'Product Key' and deselect 'automatically activate when
online'.
Once installed, do the regedit:
-navigate to
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/CurrentVersion/Setup/OOBE
-change
MediaBootInstall from "1" to "0".
THEN
At a Cmd Prompt type in and enter:
slmgr /rearm
Close the Cmd Prompt, click any OKs and then reboot and activate through the
System applet found in the Control Panel.
That's it.
