  1. Error 0xc000021a on Windows 10


    Hello everyone,

    My laptop with Windows 10 is showing a blue screen with the error 0xc000021a every time I try to access the Windows.

    When I turn on my laptop, it shows the message: 'Automatic Repair couldn't repair your PC' and the options: 'Shut down' and 'Advanced options'. I already tried to fix the computer on the 'Advanced options' using several methods that I found on sites and videos, but nothing I tried worked.

    For example: if I choose 'Repair your computer' and then 'Startup Repair, it returns a SrtTrail.txt error. I also tried to run a lot of commands that I found on the internet in the Command Prompt to try to fix this error, but none worked. I also can't restore the system, because it says there's no system restore points available, and I can't boot into safe mode either.

    So, I tried to reset the laptop on Advanced options > Troubleshoot > Reset this PC > Keep my files. I confirmed on 'Reset' and the laptop started to reset, but when it was about to 50% concluded, unexpectedly my laptop stopped the reset and went back to automatic repair window. I tried this procedure three times, and the same thing happened in all.

    Does anyone can help me, please? What can I do to fix this error or reinstall Windows without losing my data and my apps?

    Thank you

    P.S.: sorry for any mistakes in my text, English isn't my first language.
