If you're not using Windows Vista, there are other specific instructions for how to start Safe Mode in your version of Windows. 01 of 05 Press F8 Before the Windows Vista Splash Screen To begin entering Windows Vista Safe Mode, turn on or restart your PC. Just before the Windows Vista splash screen appears, press the F8 key to enter Advanced Boot Options. 02 of 05 Choose a Windows Vista Safe Mode Option You should now see the Advanced Boot Options screen. If not, you may have missed the short window of opportunity to press F8 in the previous step and Windows Vista is probably now continuing to boot normally assuming it's able to. If this is the case, just restart your computer and try pressing F8 again. You're presented with three variations of Windows Vista Safe Mode: Safe Mode: This is the default option and is usually the best choice. This mode will load only the absolute minimum processes necessary to start Windows Vista.Safe Mode with Networking: This option loads the same processes as Safe Mode but also includes those that allow the networking functions in Windows Vista to work. You should choose this option if you think you may need to access the internet or your local network while troubleshooting in Safe Mode.Safe Mode with Command Prompt: This version of Safe Mode also loads a minimum set of processes but will allow immediate access to the Command Prompt application. This is a valuable option if more advanced troubleshooting is necessary. Using the arrow keys on your keyboard, highlight either the Safe Mode, Safe Mode with Networking, or Safe Mode with Command Prompt option and press Enter. 03 of 05 Wait for Windows Vista Files to Load The minimum system files necessary to run Windows Vista load. Each file being loaded will be displayed on screen. You don't need to do anything here but this screen could provide a good place to start troubleshooting if your computer encounters serious problems and Safe Mode won't completely load. 04 of 05 Log in With an Administrator Account To enter Windows Vista Safe Mode, log on with an account that has administrator permissions. If you're not sure if any of your personal accounts have administrator privileges, log in using your own account and see if it works. Not sure what the password is to an administrator account on your computer?

Make any changes you need to make and then restart the computer. Assuming there are no remaining problems preventing it, the computer should boot to Windows Vista normally after a restart. It's easy to identify if a Windows Vista PC is in Safe Mode. The text "Safe Mode" will always appear in each corner of the screen when in this special diagnostic mode of Windows Vista. Upgrade Windows Windows Vista reached its end-of-life support period in April 2017. Although Vista continues to work, Microsoft no longer supports this version of Windows, so some times of problems may prove more difficult to resolve. If you can, upgrade your computer to Windows 10.
