How To Start Windows 10 In Safe Mode | Three Entry Methods

Windows 10 Safe Mode starts with only essential files and drivers; enter it through Windows Recovery Environment and choose option 4 or F4.

A broken driver, login loop, or app that crashes only during a normal boot is exactly when safe mode earns its keep. Knowing how to start Windows 10 in safe mode lets you load Windows with a limited set of files and drivers, so you can test whether the problem survives without the usual startup load.

Windows 10 can reach Safe Mode from the desktop, the sign-in screen, or Windows Recovery Environment (Windows RE) when normal startup fails. Microsoft ended free Windows 10 software updates, technical assistance, and security fixes on October 14, 2025, but its current recovery documentation still lists Windows 10 and the same Safe Mode startup choices.

Starting Windows 10 In Safe Mode From A Working Desktop

Windows 10 gives you a direct path through Recovery settings when the desktop still loads. The process restarts the PC into Windows Recovery Environment, where Safe Mode appears under Startup Settings.

1. Select Start > Settings > Update & Security > Recovery.
2. Under Advanced startup, select Restart now.
3. On the blue Choose an option screen, select Troubleshoot > Advanced options > Startup Settings.
4. Select Restart.
5. After the PC restarts to the Startup Settings list, press 4 or F4 for Enable Safe Mode.

The desktop will load with a stripped-down Windows session and “Safe Mode” shown on the screen. If the PC is encrypted, Windows may stop for BitLocker recovery before the recovery tools open; have the 48-digit recovery number available.

Use Shift And Restart When You Can Reach Power Controls

The Shift-plus-restart method reaches Windows Recovery Environment without opening Settings. It works from the Start menu and from the sign-in screen, which makes it useful when Windows loads but you cannot sign in normally.

1. Hold Shift.
2. While holding it, select Power > Restart.
3. Release Shift after the PC begins restarting.
4. Select Troubleshoot > Advanced options > Startup Settings > Restart.
5. Press 4 or F4 to start standard Safe Mode.

The next Windows session should show the Safe Mode label and use only the limited drivers and services needed for troubleshooting.

When Windows Will Not Reach The Sign-In Screen

Windows Recovery Environment can open automatically after repeated failed starts, and Microsoft also documents a manual way to trigger it. Interrupt the normal boot process twice; the third startup should enter Automatic Repair.

1. Turn on the PC and wait for the Windows logo or the manufacturer’s logo.
2. Press and hold the physical power button until the PC shuts down.
3. Turn the PC on again and repeat that forced shutdown once more.
4. Turn the PC on a third time. Windows should display Automatic Repair.
5. Select Advanced options, then Troubleshoot > Advanced options > Startup Settings > Restart.
6. Press 4 or F4 for standard Safe Mode.

Do not keep forcing shutdowns after Windows Recovery Environment appears. Once Automatic Repair or Choose an option is on screen, continue through the recovery menus instead.

Which Safe Mode Option Should You Choose?

Windows 10 offers three Safe Mode variants in Startup Settings. Standard Safe Mode is the first choice for most driver, startup, and software checks; networking or Command Prompt should be chosen only when the troubleshooting task needs them.

Microsoft’s Windows Startup Settings instructions list Safe Mode as option 4, Safe Mode with Networking as option 5, and Safe Mode with Command Prompt as option 6.

Safe Mode with Networking loads more components than standard Safe Mode, so use it only when the task needs connectivity. Safe Mode with Command Prompt is aimed at command-line work and is a poor fit when you need the normal desktop to remove an app, inspect Device Manager, or change a setting.

What Safe Mode Tells You About The Problem

Safe Mode is most useful as a comparison test, not as a repair by itself. If the problem disappears in Safe Mode, Microsoft says default settings, basic device drivers, and services are less likely to be the cause, which points your next check toward software or drivers that load during a normal startup.

• If the issue disappears, focus on software, services, or drivers that normally load outside the reduced Safe Mode session.
• If the issue began after a recent app, driver, or configuration change, test that change first rather than altering several items at once.
• If the same failure still happens in Safe Mode, Windows Recovery Environment tools such as Startup Repair or System Restore may fit the problem better.

A successful Safe Mode boot narrows the search; it does not prove that one specific app or driver is responsible. Change one suspect at a time so the next normal startup gives you a useful result.

How Do You Exit Safe Mode?

Restarting the PC is normally enough to leave Safe Mode and return to a standard Windows startup. If Windows keeps returning to Safe Mode, Microsoft documents a System Configuration check for the persistent setting.

1. Press Windows + R.
2. Type msconfig in the Open box, then select OK.
3. Select the Boot tab.
4. Under Boot options, clear the Safe boot checkbox.
5. Restart Windows.

Windows should return to a normal desktop without the Safe Mode label. If Safe boot is already cleared, leave it cleared and return to Windows Recovery Environment if the boot problem continues.

Use The Entry Point Your PC Still Gives You

The shortest successful procedure depends on how far Windows can start. Match the PC’s current state to the first step below, then use the same Startup Settings screen to choose the mode you need.

1. If the desktop loads, open Settings > Update & Security > Recovery and select Restart now under Advanced startup.
2. If the desktop or sign-in screen responds, hold Shift while selecting Power > Restart.
3. If Windows will not load, interrupt startup twice and let the third boot enter Automatic Repair, then select Advanced options.
4. In Windows Recovery Environment, select Troubleshoot > Advanced options > Startup Settings > Restart.
5. Press 4/F4 for Safe Mode, 5/F5 for Safe Mode with Networking, or 6/F6 for Safe Mode with Command Prompt.

Once Windows opens in the selected mode, troubleshoot the one change most likely tied to the failure, then restart normally and test. That keeps Safe Mode focused on diagnosis instead of turning it into a permanent startup setting.
