Open Troubleshoot settings 

You must be signed in as an administrator to use this option. If you're not already an administrator, for more info, see Create a local user or administrator account in Windows 10. The Troubleshoot option is available only if your copy of Windows 10 (Version 1607 or later) isn't activated. Once you activate, the option disappears.
