Product Key is saying it is not valid - when it is genuine.(Windows Vista) RRS feed

  • Question

  • I have been having continued problems with my laptop and the latest is the when it was updating Windows something went wrong and when I try to re-enter my Product Key it is saying not valid when I it is a genuine product key. I have tried following instructions on this site but I dont have the icon CMD.EXE.

    Please can someone advise me, as I have already spent hundreds of pounds last year on other problems with my laptop.

    Thank you in advance.
