UEFI key stretch of the program
pkeyui (I wrote about it earlier).

OEM Windows itself should bring out the key from the UEFI and to activate. If you have not done it run as administrator CMD.
Copy and paste (xxx is your key):
[COLOR=#282828][FONT=trebuchet ms][COLOR=#FF0000][B]slmgr [/B][/COLOR][/FONT][/COLOR][B][COLOR=#FF0000]/ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx[/COLOR][/B]
Wait for positive information about key installation.
Copy and paste:
[COLOR=#FF0000][FONT=trebuchet ms][B]slmgr [/B][/FONT][/COLOR][COLOR=#FF0000][FONT=trebuchet ms][B]/[/B][/FONT][/COLOR][COLOR=#FF0000][FONT=trebuchet ms][B]ato[/B][/FONT][/COLOR]
Wait for about a positive activation.

If it succeeds it all, unless you are using a bad ISO.
