Windows 10: AADSTS500011 problem, error code CAA2000B

Hi everyone, a few days ago when I was working on my computer my laptop suddenly restarted, when I turn it on it kept saying that I need to log out of my account otherwise all files I created now will be deleted, and it made me signed into a temporary account. Also when I tried logging in my school account it popped up the message saying that the resources principal named x was not found in the tenant named y, and its a AADSTS500011 problem. Currently the "temporary account message" doesn't show up anymore but I still can't find all my offline files. I have searched for several solution on the internet but it doesn't help. Anyone has any idea?

BIOS error codes

So I have motherboard with installed small LED screen, which presents BIOS error codes.

Where can I find a list of those errors. And I don't mean beep codes, but the "number" codes.

Ex after installing sound card, the motherboard startup fails with the code 15.

Example picture of code is here.

 

Windows 10 will not activate Error code 0x803F7001


Possibly there can be the problem with Microsoft activation Server, so your Windows 10 is not activated. In this scenario, you need to wait and verify if it is the issue from Microsoft’s side. But if you are getting error code 0x803f7001, you can also try these steps:

1. Open Settings app. Then go to Update and security > Activation screen > Change product.
2. Type your Windows edition product key and click Next.
3. You’ll get We couldn’t activate Windows error message.
4. Retry steps 1-3 then type your 25-characters unique product key.
5. Wait for the process to complete, Windows 10 is activated.

Hope something helps this problem
