@WAYNE_KWIATKOWSKI Hello! Welcome to the forums. Here are some things you can look at from your side that may help. What if anything is Norton logging in history that is related?

AI Overview

When Windows 11 restarts every day at the exact same time, it is usually caused by a scheduled Windows Update restart, a timed task in Task Scheduler, or a third-party maintenance app. Check your active update hours, look for scheduled tasks, or disable automatic restart settings to fix it. [1, 2]

Check Windows Update and Active Hours

  • Open Settings > Windows Update.

  • Check if an update is waiting to install or if a restart is pending.

  • Adjust your Active Hours so Windows knows when you use the PC, though updates may still try to force a reboot outside that window. [1]

Inspect Task Scheduler

  • Type Task Scheduler in the Windows search bar and open it.

  • Navigate to Task Scheduler Library and look through active tasks.

  • Check if a specific program, backup software, or update script is set to trigger a reboot at that exact time daily. [1]

Disable Automatic Restarts on System Failure

  • Press Windows Key + R, type sysdm.cpl, and hit Enter.

  • Go to the Advanced tab.

  • Under Startup and Recovery, click Settings.

  • Uncheck Automatically restart under System failure, then click OK

Conversely here are some things specific to Norton you can also review.

AI Overview

If your Windows 11 PC restarts daily at the exact same time, Norton is likely triggering a scheduled background task, full system scan, or an automatic product update that forces a reboot.

Fix Scheduled Scans and Tasks

  • Open your Norton app and click Open next to Device Security.

  • Go to Settings and look for Scans and Tasks.

  • Change the scheduled time for automatic full system scans or background optimization to a time when you are actively using the PC or turn off scheduled restarts.

  • Check Administrative Settings inside Norton and disable automatic silent updates if they coincide with your reboot time.

Repair or Reinstall Norton

  • Run the built-in Norton Support Autofix tool to repair corrupted background components.

  • If the daily crashes persist, completely uninstall Norton using the official removal tool, then download and install a fresh copy from Norton. [1, 2]
