Windows 8 comes with a handy tool for troubleshooting your computer: the Advanced Startup tool. Accessing it can be fiddly, but you can launch it from the command line.
The Advanced Startup tool is an extra hidden option of the Shutdown service that allows you to perform basic troubleshooting functions during startup, including performing a PC refresh or reverting to a previous restore point.
As Tech Support Alert explains, if you only want to access the advanced setup utility once, you can enter the following command into any command prompt:
shutdown.exe /r /o /f /t 00
This will reboot your PC into the Advanced Startup mode and you can click "Troubleshooting" from there. You can make this easy to access in the future by right-clicking your desktop, creating a new shortcut, and pasting the command above in the "Type the location of the item" field.
