About windows vista activation code

I suggest to upgrade to Windows 7 instead of downgrading because Windows 7 has better performance than Vista. But if you still want to go to Windows XP you have 2 choices.
The first is to format the drive where Vista is installed and to install fresh copy of Windows XP.
Second choice is to install Windows XP as second OS and at the end of the installation, at activation step, you have to choose activation by Phone. Then you should call Microsoft Helpdesk and provide the code of your Windows XP to the operator and tell him that you need downgrading Vista code. Then he will guide you to the rest of the activation and the downgrade of Vista.

Good luck!

there are lot of activation codes for vista.
to have the license activation code. buy an original WINDOWS VISTA installer... there you can find the activation code...

The Windows product code is on the Window label on the bottom of the laptop.
This is the Windows product installation code.
After Windows is installed then you activate the Windows license via the Internet or by the phone.

HI,

You can buy the windows vista from the below link and you will get a valid key:

each key is unique. The only way to tell if that is a valid key is to do a fresh install of windows using that key then trying to activate windows.
