How did you get Windows 7? Was it retail? Did you buy it from the MS website.

That code normally means Key already active on a system. If you tried to go back to Vista, I could see this happening. All you have to do is use the phone method and call MS to get that sorted.

For 7, We need more info here on how you obtained Win7.

With any luck, calling MS for phone activation is all you will have to do, but it is rare on a never installed before copy(but more common with copies that had been factory installed.).

You can reactivate your genuine Windows 7 installation by performing the following:

1. Click on the Start button and in the Start Search box type in: "slui.exe 4" without the quotes, don't forget the 4.

2. Press the Enter key on your keyboard.

3. Select your Country.

4. Follow the instructions for phone activation (no charge).

NOTE: When you call that number, you will first hear an Automated Voice. If the Automated Voice gives you an option to talk to a Live Activation Rep, select that option. If not, do not enter any numbers. This should force the Automated Voice to transfer you to a Live Activation Rep. Trying to activate thru the Automated Voice will not work, in your case, only thru the Live Activation Rep
