This article will help you to fix "An unexpected error has occurred. The troubleshooting wizard can't continue." message for troubleshooters in Windows 10.

We all know that Windows 10 comes with built-in troubleshooters which can help you to fix issues occurring in different features. But what if you can not start or run these troubleshooters? Well, recently we faced this problem where the troubleshooting wizard quits and doesn’t perform any operation when requested. Here is what it has to say:

An unexpected error has occurred. The troubleshooting wizard can’t continue.

[FIX] An Unexpected Error Has Occurred. The Troubleshooting Wizard Can't Continue.

This may occur with any of the built-in troubleshooter present in your Windows 10. Rebooting the system is great idea after getting into this issue but it didn’t helped us either. Running System File Checker or DISM commands may help. If the problem still can’t be suppressed, you should try these fixes and see if they can help you:

FIX : “An Unexpected Error Has Occurred. The Troubleshooting Wizard Can’t Continue.” Error In Windows 10

FIX 1 – Using Services Snap-in

1. Press W8K + R and type services.msc in the Run dialog box, hit Enter key to open Services snap-in.

Services Windows 10

2. In Services window shown below, make sure following services are running and have corresponding Startup type:

Diagnostic Policy Service – Automatic

Diagnostic Service Host – Manual

Diagnostic System Host – Manual

[FIX] An Unexpected Error Has Occurred. The Troubleshooting Wizard Can't Continue.

Once you set these services to their correct Startup type and running Status, close Services and make a reboot. After restating machine, you should be able to use troubleshooters without any error.

FIX 2 – Using Registry Editor

Registry Disclaimer: The further steps will involve registry manipulation. Making mistakes while manipulating registry could affect your system adversely. So be careful while editing registry entries and create a System Restore point first.

1. Press W8K + R and put regedit in Run dialog box to open Registry Editor (if you’re not familiar with Registry Editor, then click here). Click OK.

Windows 10 Registry Editor

2. In the Registry Editor window, navigate to following registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\ScriptedDiagnostics

[FIX] An Unexpected Error Has Occurred. The Troubleshooting Wizard Can't Continue.

3. Right click on ScriptedDiagnostics registry key and select Delete and confirm the operation on prompt.

4. Similarly delete ScriptedDiagnosticsProvider registry key (HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\ScriptedDiagnosticsProvider), which is located just below ScriptedDiagnostic registry key you deleted in previous step. Close Registry Editor and reboot to make changes effective.

The issue should no longer persist after your restart your computer.

That’s it!
