How to set a new default auto-restart deadline for updates on Windows 10

[Windows Central]

If you're constantly rescheduling a restart to apply updates, use this guide to specify a new default schedule to automatically reboot your PC on Windows 10.
On Windows 10, when a new update installs, you get a notification letting you know that your device will restart automatically outside of your "active hours" to apply the new changes, and as needed, you can always reschedule a restart using the Windows Update settings.
The only caveat is that you can only postpone a restart for up to seven days, and it's a manual process that you have to do every time a new update becomes available. However, if you find yourself rescheduling a deadline on every update, it's possible to configure a policy in Group Policy or modify the Registry to specify a new default deadline (up to 14 days) that Windows 10 will use to restart your device automatically.
In this Windows 10 guide, we'll walk you through the steps to change the default schedule that your computer uses to restart automatically to apply system updates.
