A 「clean boot」 starts Windows with a minimal set of drivers and startup programs, so that you can determine whether a background program is interfering with your game or program. This is similar to starting Windows in Safe Mode, but provides you more control over which services and programs run at startup to help you isolate the cause of a problem. For more detail, please refer to How to perform a clean boot in Windows.

1. Type and search [System Configuration] in the Windows search bar①, then click [Run as administrator]②. 
   
2. On the [Services] tab of System Configuration③, check the box [Hide all Microsoft services]④, select [Disable all]⑤, then select [Apply]⑥. 
   
3. On the [Startup] tab of System Configuration⑦, click [Open Task Manager]⑧. 
   
4. On the [Startup] tab in Task Manager⑨, for each Enabled startup item, select the app⑩ and then select [Disable]⑪. 
   
5. Close Task Manager.
6. On the Startup tab of System Configuration, select [OK]⑫, then select [Restart]⑬. 
    
   
7. When you restart the device, it will be in a clean boot environment. If your problem does not occur while the device is in a clean boot environment, then you can determine which startup application or service is causing the problem by systematically turning them on or off and restarting the device. 
   Turning on a single service or startup item and rebooting each time, repeat this process to find the problematic service or application
8. After you determine the startup item or the service that causes the problem, contact the program manufacturer to determine whether the problem can be resolved, or run Windows with the service unchecked or the Startup item Disabled. 
   Note: If you need to reset the device to start normally, please clear the check box [Hide all Microsoft services], select [Enable all], then select [Apply]. In Task Manager, enable all of the startup programs you had Disable before, select [OK] on the Startup table of System Configuration, then select [Restart].

If the problem persists, please continue to the next troubleshooting.
