How to disable Windows 11 automatic reboots?

For anyone that needs it, the bat file to shift your active hours is a workable solution, but it does open the command prompt every hour for a split second, which is kind of irritating. To stop the window from showing up, you can wrap the bat file in a VBS script that runs it in a hidden shell.

Create a file next to your bat file ending in a ".vbs" extension, and add this logic:

Set oShell = WScript.CreateObject ("WScript.Shell")

oShell.run "C:\PATH\TO\YOUR\BAT\FILE\update_active_hours.bat", 0

Make sure you update the path to the bat file and use double backslashes.

Next, in your scheduled task, edit it so that it runs:

"C:\Windows\System32\wscript.exe"

With the argument of:

"C:\PATH\TO\YOUR\BAT\FILE\launch_update_active_hours.vbs"

Someone could take the time to actually put the entire bat files contents into the VBS script so you'd only need one file, but this works fine. Additionally, you may need to enable vbscript for this to work.

If you turn your computer off in the end of your journey, you will not be affected by the auto restart applied after an update if your computer is not in use.

All the solutions mentioned here is for those who do not turn the computer ever, like me.

The registry add mentioned before is the better solution for the auto restart without prompt.

Or maybe in one recent update, windows correct the restart without prompt.

I didn't notice because I already using the registry entry solution.

Fell free to something else regard this natter.

I'm just a user who doesn't know much but for me all I did was go to settings, search for update, clicked "advance options" and toggled the "notify me when a restart is required to finish updating" to "On". Now it has to asks me if I want to restart.

for /f "tokens=*" %%a in ('powershell "(Get-Date).Hour"') do set startHour=%%a

set /a "endHour=(%starthour%+18)%%24"

reg add HKLM\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings /v ActiveHoursStart /t REG_DWORD /d %startHour% /f

reg add HKLM\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings /v ActiveHoursEnd /t REG_DWORD /d %endHour% /f

There should be no modulus in the first line. Powershell ALWAYS returns a 24 hour integer for the command (Get-Date).Hour. If it's 5:00 in morning or 5:59, it returns 5. If it's 3:29 PM, it returns 15.

The second line adds 18 hours and uses modulus to ensure the time wraps at midnight, so ( 15 [3PM] + 18 ) % 24 = 33 % 24 = 9 [AM].

Run it at 12 PM and 12 AM... or 9AM and 9PM... you'll always have 6 hour overlap. It's infallible.
