Advanced startup options (including Safe Mode)

You can use the Advanced Startup Options screen to start Windows with advanced troubleshooting modes. You can access the menu by turning on your computer and pressing the F8 key before Windows starts.

Some options, such as Safe Mode, start Windows in a specific state where only the essentials start. If the problem doesn't recur after starting in Safe Mode, you can rule out the default settings and basic device drivers and services as possible causes. Other options allow Windows to start with advanced features for use by system administrators and IT professionals. For more information, see the Microsoft IT Pro website.
