How can I prevent Garmin Express from causing high CPU load

1. Disable background running:
- Open Garmin Express
- Click on the gear icon to access settings
- Uncheck the option "Always keep Garmin Express running in background"[1][2]

2. Disable automatic startup:
- Open Windows Task Manager
- Go to the "Startup" tab
- Find Garmin Express in the list
- Select it and click "Disable"[1]

3. Launch manually and quit after use:
- Only open Garmin Express when you need to connect your watch or update your device
- Remember to close the application completely after you're done using it[1]

4. Restart Windows Management Instrumentation Service:
- If you notice high CPU usage associated with the WMI Provider Host process, try restarting this Windows service[5]

5. Update Garmin Express:
- Ensure you're running the latest version of Garmin Express, as newer versions may have performance improvements

6. Check for Windows updates:
- Keep your Windows operating system up to date, as this can sometimes resolve performance issues

If these steps don't resolve the high CPU usage, you may want to consider uninstalling and reinstalling Garmin Express. In some cases, users have reported that older versions of Garmin Express (e.g., version 6.19) caused high CPU usage, so updating to the latest version might help[3].

Remember that while these solutions can help reduce CPU load, they may also mean that Garmin Express won't automatically sync or update your device in the background. You'll need to manually open the application when you want to perform these tasks.
