Windows 11 is fast, modern, and secure, but it can still run into problems such as startup errors, random freezes, slow performance after an update, driver conflicts, or apps that crash on launch. In these situations, enabling Troubleshooting Mode in Windows 11 helps you start Windows with minimal components and access repair tools so you can identify what is breaking your system and fix it safely.
In Windows 11, “troubleshooting mode” usually refers to a set of recovery and diagnostic options rather than one single switch. These include Advanced Startup, Safe Mode, Startup Repair, System Restore, and Clean Boot. Separately, in enterprise security contexts, Microsoft Defender for Endpoint Troubleshooting mode is a special setting that helps administrators troubleshoot Defender on a device.
When Should You Use Troubleshooting Mode in Windows 11?
Use Windows 11 troubleshooting options when normal booting is not enough to diagnose the problem or when you suspect a startup app, service, or driver is causing instability.
- Windows 11 is stuck in a boot loop or hangs during startup
- PC is very slow after a Windows update or driver installation
- Driver and hardware conflicts (blue screens, missing devices, frequent disconnects)
- Suspicious behavior that may indicate malware or unwanted software
- Apps crash immediately after opening or won’t install correctly
Method 1: Enable Troubleshooting Options Using Advanced Startup (Recommended)
Advanced Startup is the most reliable way to access Windows 11 repair tools, including Safe Mode and Startup Repair. This works best when you can still open Settings, but it can also be reached from the login screen.
Steps (from Windows Settings)
- Press Windows + I to open Settings.
- Go to System and select Recovery.
- Under Recovery options, find Advanced startup and click Restart now.
- After restart, on Choose an option, select Troubleshoot.
- Select Advanced options to see repair tools.
From Advanced options, you can commonly access:
- Startup Repair to automatically fix boot problems
- Startup Settings to boot into Safe Mode variants
- System Restore to roll back system changes (if restore points exist)
- Uninstall Updates to remove problematic quality or feature updates
- Command Prompt for advanced repairs (SFC, DISM, boot fixes)
How to Enter Safe Mode from Advanced Startup
Safe Mode is one of the most effective troubleshooting environments because it loads only essential drivers and services.
- Go to Troubleshoot then Advanced options then Startup Settings.
- Click Restart.
- On the startup menu, press:
- 4 for Safe Mode
- 5 for Safe Mode with Networking
- 6 for Safe Mode with Command Prompt
Method 2: Use a Clean Boot to Identify Problem Apps and Services
If Windows boots but runs poorly, freezes, or crashes, a Clean Boot helps you isolate whether third-party services or startup apps are the cause. Unlike Safe Mode, Clean Boot still uses a normal Windows environment, but with most non-Microsoft services disabled.
- Press Windows + R, type msconfig, and press Enter.
- In System Configuration, open the Services tab.
- Check Hide all Microsoft services, then click Disable all.
- Go to the Startup tab and open Task Manager.
- Disable non-essential startup items, then restart.
If the issue disappears after Clean Boot, re-enable services and startup apps in small groups to find the exact conflict.
Method 3: Access Troubleshooting When Windows 11 Will Not Boot
If you cannot sign in, you can still reach Advanced Startup:
- On the sign-in screen, click the Power icon.
- Hold Shift and click Restart.
- Then go to Troubleshoot and Advanced options.
If the PC cannot reach the sign-in screen, Windows may automatically open recovery after multiple failed boots. You can also use a Windows 11 installation USB to open Repair your computer and then access the same troubleshooting menus.
Enterprise Note: Microsoft Defender for Endpoint Troubleshooting Mode
In business environments, Microsoft Defender for Endpoint troubleshooting mode is used to troubleshoot Defender Antivirus features on a device and is typically managed from the Microsoft Defender portal. If your organization uses tamper protection, administrators may need to account for those protections when troubleshooting.
FAQ: Quick Answers
Is Troubleshooting Mode the same as Safe Mode in Windows 11?
No. Troubleshooting mode is a general term for the diagnostic and recovery options available in Windows 11. Safe Mode is one specific option within those tools.
Will Safe Mode delete my files?
No. Safe Mode changes how Windows starts but does not erase personal files. However, repairs like “Reset this PC” can, depending on choices you make.
What should I try first if Windows 11 won’t boot?
Use Advanced Startup and run Startup Repair, then try Safe Mode to remove recently installed drivers, apps, or updates.
Conclusion
Enabling troubleshooting mode in Windows 11 is about using the right diagnostic tool at the right time. Start with Advanced Startup to access repair options, use Safe Mode for driver and malware related issues, and use Clean Boot to pinpoint problematic third-party services and startup applications. With these methods, you can systematically isolate the cause of crashes, boot loops, and performance issues and restore a stable Windows 11 system.
