    Lost activation after resizing partition


    I don't know if the right place, but I'll share my problem. Last days I resized my C: drive in order to put Linux on my free space and dual boot. Since then my windows lost his activation, gave me eroor code 0xC004F012 and don't want to shut down - just log off. Have someone experienced this and any ideas for fixing. Thanks in advance.

    If you are running version 10586, just go to activation menu, select 'change product key' and enter old 7/8 key.

    Can't say I have encountered this problem...I do have Linux in multiboot - seems odd that your Windows installation is affected though - as @cereberus has suggested reactivate with the original key or restore.
