# Change Active Hours

Windows 10 has a feature called Active Hours which allows users to specify the hours they’re more likely to use the computer to prevent Windows Update from restarting the system automatically. Enabling this option will prevent your computer from automatically restarting while scanning in the field.

1\. Open the Windows Updates & Security Settings app by selecting Start →  Settings → Update & security.

2\. Click the “Change active hours” option and specify the time you’ll be actively using your computer. The maximum active length of time you can set is 12 hours. Any other time range will be marked as invalid. We recommend setting the active hours to match the times you’ll spend scanning in the field.
