Sometimes it's necessary to start Windows in Safe Mode to properly troubleshoot a problem. Typically, you'd do this via the Startup Settings menu (Windows 8) or via the Advanced Boot Options menu (Windows 7, Vista, and XP).
However, depending on the problem you're having, it might be easier to make Windows boot in Safe Mode automatically, without having to boot to one of the advanced startup menus.
Follow the instructions below to configure Windows to reboot directly into Safe Mode by making changes in the System Configuration utility, often called MSConfig.
Note: You'll need to be able to start Windows normally to do this. If you can't, you'll need to start Safe Mode normally. See How To Start Windows in Safe Mode if you need help.
Time Required: It should take less than 10 minutes to configure MSConfig to boot Windows to Safe Mode.
In Windows 8, open Run from the Apps screen or see Tip #1 below for a few shortcuts.
In Windows 7 and Windows Vista, click on the Start button.
In Windows XP, click on Start and then click Run.
In the text box, type the following:
Tap or click on the OK button, or press Enter.
Note: Do not make changes in System Configuration other than those outlined here to avoid causing serious system issues. This utility controls a number of startup activities other than those involved with Safe Mode.
Click or tap on the Boot tab located at the top of the System Configuration window.
In Windows XP, this tab is labeled BOOT.INI
Check the checkbox the left of Safe boot (/SAFEBOOT in Windows XP).
The radio buttons under the Safe boot options start the various other modes of Safe Mode:
- Minimal: Starts the standard Safe Mode.
- Alternate shell: Starts Safe Mode with Command Prompt.
- Network: Starts Safe Mode with Networking.
See Safe Mode: What It Is and How To Use It for more information on the various Safe Mode options.
Click or tap on OK.
You will then be prompted to either Restart, which will restart your computer immediately, or Exit without restart, which will close the window and allow you to continue to use your computer, in which case you'll need to restart manually.
After restarting, Windows will automatically boot to Safe Mode.
Important: Windows will continue to start in Safe Mode automatically until System Configuration is configured to again boot normally, which we'll do over the next several steps.
If you'd prefer to continue to start Windows in Safe Mode automatically each time you reboot, for example if you're troubleshooting a particularly nasty piece of malware, you can stop here.
When your work in Safe Mode is complete, again start System Configuration as you did in Steps 1 and 2 above.
Choose the Normal startup radio button (on the General tab) and then tap or click on OK.
You'll again be prompted with the same restart your computer question as in Step 6. Choose one option, most likely Restart.
Your computer will restart and Windows will start normally... and will continue to do so.
