Perform a Clean Boot


Microsoft experts recommend to perform a clean reboot to find out if third-party programs or autoload elements cause 0xc00ce556 error. When installing third party programs, change Windows settings, including the registry. They often lead to conflicts that raise different questions. In addition, it may be the fault of some applications that are launched immediately after each launch. Therefore, disabling unwanted programs that run at startup, including external applications, can be a great help in determining the true cause. Follow these instructions:

  • Start the search in the taskbar with the keys Win + Q, type msconfig and press Enter.
  • Go to the Services tab and check the box “Hide all Microsoft services”. Click Disable all.
  • Click the Start tab and click the only visible link to Open Task Manager.
  • When the console with the “Home” tab highlighted appears, select each item and click “Disable”.
  • Go back to the System Setup window again, select OK and restart the device.
  • The device is launched with a minimum set of programs. If you do not see the 0xc00ce556 error returned by the scanner, this is one of the programs that caused the mess.

Perform a new installation of your operating system.
