Reset this PC
This normally fixes most problems, however, depending on the options. For example "Remove Everything" will erase all files and settings, programs/apps.
System Restore will allow you to revert the computer's state (including system files, installed applications, Windows Registry, and system settings) to that of a previous point in time. System Restore Points are usually created automatically before the installation of a program/app or a Windows Update. This is usually a good method to try first.
Automatic Repair will attempt to do exactly what it says. Windows will try to detect any potential problems that are preventing successful boot-up and fix them automatically.
Startup Settings will show a list of various boot-up methods, including Safe Mode. Safe Mode attempts to boot Windows using a very limited and primitive set of drivers. This can be used to diagnose incompatible/corrupt device drivers that are preventing Windows from booting up. A classic example of this could be recent graphics card or similar device driver has updated, and is not currently compatible with Windows 10. Or simply the driver installation failed and corrupted the previous version. If your System is able to boot up into Safe Mode, it is almost a certainty that a device driver is to blame. Run a System Restore to take the computers state back to a point before any new drivers were installed and work from there.
