Postup řešení

  1. 1 Press Windows key + R to open the Run dialog. Type 'services.msc' and press Enter. This opens the Services window, which lists all background services. Look for 'Performance Logs & Alerts' service. If it's not running, right-click it and select 'Start'. This service is responsible for collecting performance data, and if it's stopped, profiling cannot start.
  2. 2 Press Windows key + X and select 'Terminal (Admin)' or 'Command Prompt (Admin)'. Type 'net start pla' and press Enter. This starts the Performance Logs & Alerts service from the command line. If you get an error, it means the service is disabled; we'll fix that next.
  3. 3 Open the Services window again (Win+R, type 'services.msc'). Double-click 'Performance Logs & Alerts'. In the 'Startup type' dropdown, select 'Automatic'. Click 'Apply' and then 'OK'. This ensures the service starts automatically every time Windows boots, preventing future profiling failures.
  4. 4 Press Windows key + R, type 'regedit', and press Enter. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\pla. In the right pane, double-click 'Start'. Set the value to 2 (which means Automatic). Click OK. This is a more direct way to set the service to start automatically, bypassing any group policy restrictions.
  5. 5 Restart your computer to apply all changes. After reboot, try launching your profiling tool again. The error should be resolved.
