Safe Mode Starts Your Computer With Only Essential Programs

Safe Mode is a diagnostic startup option that loads only the drivers and services your operating system needs to run. It disables third-party software, graphics enhancements, and network features. You use Safe Mode when your computer won't start normally, when you suspect malware, or when you need to uninstall software that's causing crashes.

The steps differ between Windows and Mac, and within Windows they differ between older and newer versions. The method also depends on whether your computer will start at all or is stuck at a black screen.

Key Takeaways

  • On Windows 10 and 11, hold Shift while clicking Restart from the sign-in screen to reach the boot menu, then select Safe Mode.
  • On Windows 7 and earlier, press F8 repeatedly as the computer starts, before the Windows logo appears.
  • On Mac, restart and hold Command+S to enter Safe Mode, or hold Shift if your Mac uses Apple Silicon.
  • Safe Mode runs without most programs and network access, so it is slower and some features will not work.
  • If your computer will not start at all, you may need to use a recovery disk or contact a technician.

Starting Safe Mode on Windows 10 and Windows 11

If your computer starts normally but you want to enter Safe Mode, go to the sign-in screen. Hold Shift and click the power icon in the bottom right corner. Select Restart while still holding Shift. Your computer will restart into the Windows Recovery Environment.

Once the recovery menu appears, click Troubleshoot, then Advanced Options, then Startup Settings. Click Restart. Your computer will restart again and show a numbered list of startup options. Press 4 for Safe Mode, 5 for Safe Mode with Networking (which includes internet access), or 6 for Safe Mode with Command Prompt (for advanced users). Your computer will then load Safe Mode.

If your computer is already stuck or crashing before you reach the sign-in screen, restart it three times in a row by holding the power button for ten seconds each time. After the third restart, Windows will automatically boot into the recovery menu, and you can follow the steps above from Troubleshoot onward.

Starting Safe Mode on Windows 7 and Earlier Versions

Turn on your computer or restart it. As soon as you see the first screen (before the Windows logo appears), press F8 repeatedly, about once per second. Timing matters — if you press F8 too late, Windows will start normally and you will have to restart and try again.

When the Advanced Boot Options menu appears, use the arrow keys to highlight Safe Mode, Safe Mode with Networking, or Safe Mode with Command Prompt. Press Enter. Your computer will load Safe Mode, which may take longer than a normal startup.

If F8 does not work, your computer may have a different key. Some Dell, HP, and Lenovo machines use F5 or another function key instead. Check your computer's startup screen or manual for the correct key, or try pressing Escape to see a menu of options.

Starting Safe Mode on Mac

Shut down your Mac completely. Turn it back on and when ready hold Command+S (the Command key and the letter S together). Keep holding until you see white text on a black screen. This is Single-User Mode, which is Mac's equivalent of Safe Mode. Release the keys and wait for the command prompt to appear.

If your Mac uses an Apple Silicon chip (M1, M2, M3, or later), the process is different. Shut down your Mac, then turn it on and hold the power button until you see "Loading startup options." Click Options, then click Continue. You will be asked to sign in. After signing in, your Mac will start in Safe Mode, and you will see "Safe Boot" in the login window.

On older Intel-based Macs, you can also restart and hold Shift instead of Command+S. This loads Safe Mode with a graphical interface rather than the command line.

What Safe Mode Does and Does Not Do

In Safe Mode, your computer runs only essential system files and drivers. It does not load startup programs, browser extensions, or third-party services. This means antivirus software, cloud storage apps, and printer drivers may not work. Your internet connection may be slower or unavailable unless you chose Safe Mode with Networking.

Safe Mode is useful for removing malware because malicious software often cannot run in this limited environment. It is also useful for uninstalling programs that crash during normal startup, because the program will not load automatically. You can also use Safe Mode to troubleshoot driver problems or test whether a hardware issue is caused by software.

Safe Mode is not a permanent solution. Once you restart your computer normally, all your programs and settings return. Safe Mode is a diagnostic tool, not a repair tool.

When Your Computer Will Not Start at All

If your computer will not start, does not reach the sign-in screen, or shows only a black screen or error message, Safe Mode may not be reachable through the normal steps above. In this case, you have two options: use a recovery disk or contact a technician.

A recovery disk is a USB drive or DVD that contains Windows or Mac startup files. You can create one on another computer using Microsoft's Media Creation Tool (for Windows) or Apple's Recovery Disk Assistant (for Mac). Insert the disk, restart your computer, and press the key shown on screen to boot from the disk. From there, you can access repair tools or reinstall your operating system.

If you do not have another computer available or are not comfortable with these steps, a local computer repair shop can diagnose the problem and may be able to recover your data or repair the system.

Exiting Safe Mode

To return to normal mode, straightforward restart your computer. It will boot normally and load all your programs and settings as usual. You do not need to change any settings or press any keys — a normal restart is all that is required.

If you made changes in Safe Mode (such as uninstalling a program or removing malware), those changes will remain after you restart normally. Safe Mode itself is temporary and does not alter your system.

Frequently Asked Questions

Why is my computer so slow in Safe Mode?

Safe Mode disables graphics acceleration and runs fewer background services, so everything is slower. This is normal and expected. Once you restart normally, your computer will return to its usual speed.

Can I use the internet in Safe Mode?

Not in standard Safe Mode. You must choose Safe Mode with Networking (Windows) or hold Shift instead of Command+S (Mac) to keep internet access. Standard Safe Mode disables network drivers to isolate the system for troubleshooting.

Will Safe Mode delete my files?

No. Safe Mode only changes which programs load at startup. Your files, documents, and settings remain unchanged. You can safely use Safe Mode without risk of data loss.

What if I cannot press F8 in time on Windows 7?

Try pressing F8 as soon as you see any text on screen, even before the Windows logo. If that does not work, restart and try again — it often takes a few attempts to get the timing right. Some computers also respond to Escape or Del instead.

Is Safe Mode the same as a factory reset?

No. Safe Mode is temporary and reversible — you restart normally to exit it. A factory reset erases all your files and programs and returns your computer to its original state. They are completely different tools used for different problems.
