Win10 startup blue screen 0xc000021a solution (without reinstalling the system)

I originally connected to another computer remotely in the laboratory to run the model, but the running time took a long time , a bit stuck, so restart. After a period of time, I still couldn't connect remotely. I ran to take a look and found that

termination code 0xc000021a.

I tried restarting, automatically repairing, restoring the latest settings, etc., but none of them worked.

After searching around, it was said that the core system files were damaged, and then someone else said that the memory was damaged and there was a problem with the graphics card, which scared me to death. Some people say that they installed something that shouldn’t be installed, but I didn’t install anything before restarting!

I also tried to find paid rescue on Taobao, but found out that I was asked to reinstall it for 30 yuan. Pulled it down, it contained too much stuff, and I didn’t plan to reinstall it.

Finally found a reliable one, and finally found that the core system files were really damaged

The method is as follows:

1. Reboot continuously and enter automatic Diagnosis, after the diagnosis is useless, select the advanced option. (Sorry I didn’t take a photo, so there is no picture)

2. Click “Troubleshoot”, click “Advanced Options”, click “Startup Settings”, click “Restart”, I almost forgot to press F, choose anyway safe mode. If you can enter safe mode, it means there is no big problem. If you can't even enter safe mode, you can reinstall.

3. Enter safe mode (that is, the low-resolution version of Windows '-'), press the win key between ctrl and alt on the keyboard, enter "cmd", right-click and run in administrator mode

4. Enter chkdsk c: /R and run for a while
