Upgrade Window XP Home to Pro

I needed to connect my Windows Home computer to the domain but I couldn't because it is Home.  So I was looking up what it would cost to upgrade and found this and it Worked, which was suprising and cool.  Only down side is that it still won't allow Remote Desktop.

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

1. Open Registry Editor (regedit).
2. Navigate toHKEY_LOCAL_MACHINE/SYSTEM/ControlSet00X/Control/ProductOptions, where ControlSet00X is the one with the highest number.
3. Delete the ProductSuite registry key.
4. Then, create a new DWORD value and named it as Brand.
5. Set the “Brand” value data as 0.
6. Reboot the system.
7. On boot up after the BIOS screen, press F8 to display Windows XP Startup Menu.
8. 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.
