Win10 update driver after the splash screen solution

A netizen used VHD to install Win10 system on his computer. After installation, there was no problem. After that, he updated the driver with the driver wizard. After the reboot, the splash screen appeared, and the Win10 system could not enter.

The original system of his computer is installed with Win8. In order to take advantage of the Win10 system, the Win10 technology preview version is installed at risk. Now when you start Win10, it will flash, but Win8 will not. This problem is most likely to be on the updated driver.
Solutions
Since there is no way to enter the Win10 system, you can try to enter the Win10 security mode and roll back the driver in safe mode. Or try the advanced boot mode to see if you can start Win10 by using the last correct configuration. If not, you can only reinstall the Win10 system.
User analysis, it is estimated that the main reason is the graphics card driver, the current graphics card driver is not very compatible with Win10. If you want to update the driver on Win10, it is recommended to skip the update of the graphics card driver for the time being.
