    Errors 0xC004F012 & 0x8004f807 Can't activate windows after refreshing the install.


    I've been having a horrible year so far, my PC keeps breaking every few weeks, and I found its because one of the drives on my RAID0 died which cost me thousands in assets and work. And windows was constantly crashing because of the missing drive.
    I refreshed my installation and now my windows won't activate.

    First message in yellow: "We can't activate Windows on this device because you don't have a valid digital license or product key. If you think you do have a valid license or key, select Troubleshoot below. Error core: 0xC004F012"

    After doing so I get: "We can't activate Windows on this device right now. You can try activating again later or go to the Store to buy a genuine Windows. 0x8004f807

    I tried changing the key and using the original key for this installation and I get the same exact error as above. This key is from 2018, my Windows is up to date. I have a MS account linked and I'm pretty sure it was linked to the key as well.

    Please help me, I'm honestly on the edge of having a mental breakdown from all the **** I've been through recently. I can't afford a new key or a replacement drive for all the work I've lost.

    I'm an advanced user, feel free to give me complex answers, I know how a computer works and how to build them.

    Lucky you. After my own refresh the language is wrong, no newly installed app is in the start list, windows activation possibility has gone (error 0xC004F012) and the app store may not be opened.
