Windows 11 seems vers have désactivé all ways vers get around Auto Mise à jour Redémarrages. Existe-t-il un workaround?

I run Matlab simulations that sometimes take weeks to finish and when Windows restarts I lose all my work so I really need a way to stop auto restarts.

Windows 11 seems to have disabled all ways to get around Auto Update Restarts. Existe-t-il un still a workaround?

It used to be possible to set NoAutoRebootWithLoggedOnUsers in:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU

if you also set AUOptions to 4 in the same location but this ne fonctionne pas chez moi now.

Windows will not reboot during working hours. My solution is to run a tâche planifiée that changes the working hours in le registre, say every hour or two, so that it is always a working hour. I coded up this 4 line cmd command batch file program:
`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


I then used Windows Planificateur de tâches to make this .bat script run every hour for 1 day and repeat daily.

To stop pop-ups of the command windows, make task scheduler start the program/script "cmd.exe"

and put as its arguments:

`/c start /min C:\work\disableautoupdate.bat ^& exit`

(Substitute your own filename above for C:\work\disableautoupdate.bat)

Cela va minimise the window your script runs in.

**Tested: Ça fonctionne!** J'ai installé an update requiring a restart on 31-May. I am informed that this restart will happen outside of working hours. As of 20-June, 22 days later, no restart had taken place.

I figured out how to incorporate @Jonathan's feedback. It is easier to do modulo maths (and to get the hour independent of locale/region/format preferences) with powershell commands. It's still a cmd batch file, but it calls powershell. Reduces to 4 lines and should work everywhere.
