Many users may encounter problems when using Windows 11 or 10 on their computers. Windows 10 fails to update or runs slowly, the PC gets stuck with blue or black screens frequently, or it crashes constantly. Worse still, Windows 10 or Windows 11 won't boot. When your computer behaves like this, you need to fix Windows 11 or Windows 10.
We will show you how to fix Windows 10 precisely with DISM and SFC commands via CMD. If these Windows repair commands do not work, you can seek help from the Windows Repair Service. If your computer fails to start, we recommend using bootable data recovery software to retrieve data from the computer.
