WinXP Home to WinXP Pro

Otro tema antiguo pero que me ha vuelto a surgir y he tenido que volver a buscar la solución. Para que no se me olvide la apunto aquí.

To convert and upgrade Windows XP Home to Windows XP Professional, follow procedure below.

* Open Registry Editor (regedit).

* Navigate to                        HKEY_LOCAL_MACHINE/SYSTEM/ControlSet00X/Control/ProductOptions, where ControlSet00X is the one with the highest number.

* Delete the ProductSuite registry key.

* Then, create a new DWORD value and named it as Brand.

* Set the “Brand” value data as 0.

* Reboot the system.

* On boot up after the BIOS screen, press F8 to display Windows XP Startup Menu.

* Choose Last Known Good Configuration (LNG) and hit Enter.

Windows XP will start up as usual. After logging into the desktop, check the system properties to verify that it’s now Windows XP Professional.
