How to Start Your PC in Safe Mode

What Safe Mode Does and When to Use It

Safe Mode is a diagnostic startup option that loads Windows with only the bare minimum drivers and programs needed to run your computer. It disables most third-party software, graphics enhancements, and network features. You use Safe Mode when your PC is crashing, freezing, infected with malware, or behaving strangely — because Safe Mode lets you troubleshoot without interference from whatever is causing the problem.

Safe Mode is not a permanent state. Once you restart normally, Windows returns to its regular configuration. Think of it as a stripped-down version of Windows that lets you see what is actually broken without all the extra layers running on top.

Key Takeaways

Safe Mode loads Windows with only essential drivers, which helps you identify whether a problem is caused by third-party software or Windows itself.
The method to enter Safe Mode depends on your Windows version and whether your PC will start at all.
If Windows starts normally, you can reach Safe Mode through Settings or by holding Shift while restarting.
If Windows will not start, you can force Safe Mode by restarting during the Windows logo or using a recovery drive.
Safe Mode with Networking includes internet drivers if you need to download tools or updates.

Safe Mode on Windows 11 and Windows 10 (When Windows Starts Normally)

If your PC boots into Windows without freezing or crashing, the fastest route is through Settings. Open Settings by pressing Windows key + I, then go to System on the left side. Click Recovery, then click the Restart now button under "Advanced startup". Your PC will restart and show you a menu with several options.

When the menu appears, click Troubleshoot, then Advanced options, then Startup Settings. Click Restart. Your PC will restart again and show a numbered list of startup options. Press 4 to enter Safe Mode, or press 5 for Safe Mode with Networking (which includes internet drivers). Your PC will restart one more time and boot into Safe Mode — you will see "Safe Mode" in the corners of your screen.

An alternative method that works on both Windows 11 and Windows 10: restart your PC normally, then immediately hold down Shift and click the power button to shut down. Do not just restart — you must shut down while holding Shift. When you turn the PC back on, it will boot into the Advanced startup menu and you can follow the steps above.

Safe Mode When Windows Will Not Start

If your PC crashes before Windows fully loads, or if it gets stuck on the Windows logo, you need to force the startup menu. The method is to restart the PC during the Windows boot process. As soon as you see the Windows logo appear, hold down the power button until the PC shuts off completely — this takes about 10 seconds. Wait a few seconds, then turn the PC back on. Repeat this process two or three times. After the second or third forced restart, Windows will detect the problem and automatically show you the Advanced startup menu.

Once the menu appears, follow the same steps as above: click Troubleshoot, then Advanced options, then Startup Settings, then Restart, then press 4 for Safe Mode. This process can take several minutes because Windows is checking itself for errors.

If forcing restarts does not work, or if you have a recovery drive or Windows installation media, you can boot from that instead. Insert the recovery drive or media, restart your PC, and press the key shown on screen to enter boot options (usually F12, Esc, or Del — it varies by manufacturer). Select the drive or media from the list, and Windows will show you the Advanced startup menu directly.

Safe Mode on Windows 7 and Earlier Versions

Older Windows versions use a different method. Restart your PC and watch for a message that says "Press F8 to enter Advanced Boot Options" — it appears for only a few seconds, right after the manufacturer logo but before Windows starts loading. Press F8 during that window. If you miss it, restart and try again.

When the Advanced Boot Options menu appears, use the arrow keys to highlight Safe Mode and press Enter. You can also choose Safe Mode with Networking if you need internet access. Your PC will boot into Safe Mode, which looks noticeably different from normal Windows — the screen resolution is lower and "Safe Mode" appears in all four corners.

If pressing F8 does not work, your PC may have a different key. Common alternatives are F5, F12, or Del. Check your PC manufacturer's website or the manual if you are unsure. Some newer PCs with fast startup do not give you time to press F8 at all — in that case, use the Settings method described above, or force restarts as described in the previous section.

What to Do Once You Are in Safe Mode

Once Safe Mode is running, you can troubleshoot the problem. If your PC was crashing due to a recently installed program, uninstall it: go to Settings (or Control Panel on older Windows), find Apps or Programs and Features, locate the program, and click Uninstall. If a driver is causing problems, you can uninstall it the same way under Device Manager.

If you suspect malware, Safe Mode is a good environment to run antivirus software because malware often cannot run in Safe Mode. Download and run a full scan with Windows Defender (built into Windows) or a third-party antivirus tool. Safe Mode with Networking gives you internet access so you can download updated antivirus definitions if needed.

If Safe Mode runs smoothly but normal Windows crashes, the problem is likely a third-party program or driver, not Windows itself. If Safe Mode also crashes or freezes, the problem is more serious and may require professional repair or a Windows reinstall.

Exiting Safe Mode

To return to normal Windows, simply restart your PC. Windows will boot normally and load all your programs and drivers again. You do not need to do anything special — Safe Mode is only active until the next restart.

If you want to verify that you have exited Safe Mode, look at the corners of your screen. If they are blank (no "Safe Mode" text), you are running normal Windows. You can also check by opening System Information: press Windows key + Pause (or go to Settings > System > About on Windows 11), and look for "Safe Mode" in the information displayed.

Common Mistakes and How to Avoid Them

The most common mistake is not holding Shift long enough when restarting. If you click "Restart" normally without holding Shift, Windows will just restart as usual. You must hold Shift the entire time the shutdown is happening, or the advanced menu will not appear.

Another mistake is trying to press F8 too early or too late. The window to press F8 is very narrow — it happens after the manufacturer logo disappears but before the Windows logo fully loads. If you see the spinning dots or the login screen, you have missed it and need to restart again.

On newer PCs with fast startup enabled, F8 may not work at all because Windows boots too quickly. If F8 does not respond after two or three tries, use the Settings method instead — it is more reliable on modern hardware.

Frequently Asked Questions

Is it safe to use Safe Mode for a long time?

Safe Mode is designed for troubleshooting, not daily use. You can stay in Safe Mode as long as you need to fix a problem, but some features will not work — network connections may be limited, graphics will look different, and many programs will not run. Once you have solved the problem, restart normally.

Can I access the internet in Safe Mode?

Regular Safe Mode disables most network drivers. Use Safe Mode with Networking instead if you need internet access. This version loads the drivers required for your network card or Wi-Fi adapter while still disabling third-party programs.

What if Safe Mode also crashes or freezes?

If Safe Mode is unstable, the problem is likely a corrupted Windows file or a hardware issue, not a third-party program. Try running Windows Startup Repair (available in the Advanced startup menu under "Troubleshoot") or contact a technician. A full Windows reinstall may be necessary.

Will entering Safe Mode delete my files?

No. Safe Mode only changes which programs and drivers load at startup. Your files, documents, and settings remain untouched. When you restart normally, everything returns to how it was.

Can I uninstall programs while in Safe Mode?

Yes. Safe Mode lets you uninstall programs through Settings or Control Panel just as you would in normal Windows. This is actually a good reason to use Safe Mode — if a program is causing crashes, uninstalling it in Safe Mode prevents it from interfering with the uninstall process.
