    How to activate previously purchased Win10 Pro licence after reinstall?


    Hello,


    I have just reinstalled the windows 10 using the Media Creation Tool.

    The Windows is activated as Win 10 Home, although I would like to upgrade it to Win 10 Pro.

    Previously it was working like this, I purchased the Win 10 Pro upgrade from the MS Store on 23 February 2019.


    How can I upgrade? There is no product key.


    Thanks,

    Istvan

    :)

  2. Windows 10 Pro purchased but reinstalls only home. No licence key or digital licence.

    I bought Windows 10 Pro 2 years ago and at the time on that computer it worked as an in-situ upgrade without issues.

    Ive since had to change computers and reinstall and it doesn't seem to exist any more.

    The windows install is the OEM supplied Win10 home.

    When i attempt to upgrade via windows it gives me 2 options only:-

    (i) Enter a product key (which i dont have since i believe i have a digital licence)

    (ii) Link to the MS store where it offers me to purchase Win10 pro again (but i already own it).

    Looking into my Microsoft account i can see the order for Win10 Pro complete with Order number if i select "All" purchases with the correct date. If i click on "Digital" nothing shows up on the same screen.

    I seem to have no product key and no digital version of Pro tied to my account despite my order history showing i bought it (and used it previously).

    Im unable to run the Activation Troubleshooter because windows is already activated (with OEM home).

    How can i go about fixing this so i can upgrade my windows install to Pro again and how can i get it added as a digital licence correctly in the store for future reinstalls if needed?

    How to activate previously purchased Win10 Pro licence after reinstall?

    Successful transfer of Win10 Pro digital licence

    Hi I would put it this way from what I have learned:
    If you have a windows 7 (or presumably, 8 or 8.1) RETAIL channel licence (i.e. you had the discs and were previously able to install on new machines as you needed - uninstalling any others so that there was only one copy in use) then yes.

    I had upgraded my old Win7 pro licence to Win10 Pro using the free upgrade offer from MS last year.

    Now I want to use win10 pro on the new machine (which comes with Win10 Home) but I only have a digital win10 pro licence on the old machine (plus my old Win7 Pro licence).

    The digital licence to win10 pro can apparently be 'transferred' to the new machine. I haven't done this yet but I am told this is effected by using a MSA (Microsoft account) and being logged into that account on both machines.

    You then use the activation troubleshooter to select the licence on the old machine or alternatively performing a plain upgrade on the new machine and either entering the original win7 pro key or calling MS to activate over the telephone.

    We'll see if it works. I'll post back.
