How to fix error error-failed-service-controller-connect in Windows 11

Solution Steps

1. 1 Press Windows key + R, type 'services.msc', and press Enter. This opens the Services window. Look for the service that is failing (it may be listed with a red icon or in an error state).
2. 2 Right-click the problematic service and select 'Properties'. In the 'General' tab, check the 'Startup type'. If it's set to 'Disabled', change it to 'Automatic' or 'Manual' depending on the service. Click 'Apply' and 'OK'.
3. 3 Now try to start the service by right-clicking it and selecting 'Start'. If it fails, note the error message.
4. 4 If the service is not the issue, check if the Service Control Manager itself is running. Press Windows key + R, type 'services.msc', and look for 'Service Control Manager' (it's usually not listed, but you can check via Task Manager). If it's not running, restart your PC.
5. 5 If the error occurs during startup, press Windows key + R, type 'msconfig', and press Enter. Go to the 'Services' tab, check 'Hide all Microsoft services', and then disable any third-party services that might be causing conflicts. Restart your PC and see if the error goes away.
6. 6 If the error persists, run the System File Checker: press Windows key + R, type 'cmd', and press Ctrl+Shift+Enter. Type 'sfc /scannow' and press Enter. This will scan and repair corrupted system files.
