    Windows 10 won't activate after install on Win 7 machine.


    Had legit Win7 license on my PC. Bought Single use Win 10 from vendor that I have purchased from before with no issues.

    Have built a couple new machines this way. Both worked just fine.


    Bought a third and tried to install on my Win7 machine. I did not install any new hardware, just booted from DVD drive and installed it as a clean install (not saving any old files). Runs fine but won't activate. Says I don't have a digital license. But it also says it sees a home addition and mine is Pro. Never had Win 10 home addition installed, only Win7 home. I never accepted the free Windows10 so don't know where that is coming from.


    Tried to enter product key manually--no luck


    Do I need to buy a new motherboard so it will think I'm building a new machine??

    Is there any way to clean the machine and reinstall Win7 ??

    :)

  2. Installing Windows 10 using Windows 7 key

    Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

    As for getting rid of Windows, delete the Windows folder.

    Windows 10 activation question

    You get assigned a new Key in Win10 when upgrading. It looks like it might follow the same channel as your original Key. My WMC key was retail channel and my Win 10 Key shows as retail too. Hopefully that means I won;t have to worry too much when upgrading my PC.

    Windows 10 won't activate after install on Win 7 machine.

    Win.10 won't boot after installing Win.7

    Hi,

    So i installed Win.10 via the UEFI and after installing Win.7 on Legacy Mode onto a different HDD i can't boot into Win.10 (I believe can only because Win.10 was installed via UEFI)

    I tried installing the BCD Software but nope. I even tried to select my HDD but say Winload.exe error

    Even tried going into the USB and try repairing but the same thing happens
