    cant update cant activate


    Hello ive recently formated my pc with my digitaly purchased copy of windows 8 and after i finished the install (not the first time it asks for product key during install but after when your allready loged in windows)it said my windows werent activated after a boot up,i looked in microsoft community and saw an advice by a user about changing the registry key or creating if non existant and then changing it the ''mediabootinstall'' registry key or something like that anyway after that and an slmgr rearm in an elevated command prompt i managed to input my key and everything was fine untilli tryed to update andi realized i couldnt anymore so i run the update troubleshooter which reverted my machine in the not activated state,now i cant update and every now and then i get the message please activate your windows and my key is not recognized giving me a message that it is for non-core version and taht its is for upgrade and not clean install procedures,note that its my second clean install of win 8 but only this time i got this problem also the microsoft online site on which i purchased my win copy had the product as an os system and untill today it doesnt say anything about only being used as an upgrade neither my receipt does any help would be much appreciated since i dont want to pay more money to get real time support and ive allready directed my problem to the community but to no avail yet it seems noone bothers with original windows anymore and if anyone does and meets issues they resolve it without microsoft perhaps..i couldnt find a match to my issue in their database!

    Thanks for your time to read and deal with my post!

    Hi there
    If it's Windows 8.1 PRO type in the command SLUI 3

    Then enter the product key.

    Ensure though PROTECTED BOOT is turned off in the BIOS - you can leave UEFI on though.

    Cheers
