Howto prevent auto reboot¶

taken from: https://answers.microsoft.com/en-us/windows/forum/all/how-to-disable-windows-11-automatic-reboots/d7766f02-59a1-48f4-af6e-761345704ead

this sounds quite plausible, not yet tested (as of 2025-06-21)

Make a batch command file eg. disablereboot.bat, i.e. Open notepad and paste the code below:

for /f %%i in ('powershell "((get-date).Hour+18) %% 24"') do set startHour=%%i
for /f %%i in ('powershell "((get-date).Hour+12) %% 24"') do set endHour=%%i

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 

Save the file anywhere on your computer like C:\MyStuff\disablereboot.bat

Then use Task Scheduler:

Press the windows key + R at the same time and in the prompt type:

taskschd.msc

and configure to run the code Daily and repeat every hour for 1 day, i.e.:

in the right panel click Create task

name it whatever way you want in the General tab

In the Triggers tab create a new one with the contents below:

Daily, repeat task every 1 hour for duration at: 1 day

in Actions click in new with the action Start a program and in the browse locate your previous saved bat file, in this example, C:\MyStuff\disablereboot.bat.

This will keep changing your working hours so that it is never not a working hour. This way you will never get an auto reboot and you can choose yourself when to reboot.
