Hello All, Morning:
I would like to enable recovery using ReagentC in my windows LTSC 21H2 19044.5131 system using C# application so i set the app manifest by default launch ad admin.
I tried to launch the the batc file via this application but recovery is not set, if i launch the .bat file seperately the script works.
How can i launch the batch file from my app to eanble the recovery? do i need to tweak something in the registry?
Also another command prompt applciation but its not working. I have attached the codes in the notepad file : https://codefile.io/f/m11qxHjMZ1

Hi,@Kran2022. Welcome to Microsoft Q&A.
I tested the code you provided and it could successfully set the Windows RE status of Recovery to Enabled.
The following is my additional successful test solution, you could try it.
First, make sure the reagentc /enable command is available. You could try to start recovery directly through the reagentc /enable command in the command prompt.(If the command is not available, you need to correct its environment variables)
Create a WPF program and add code.
MainWindow.xaml.cs
Create the EnableRecovery.bat file and add it to the WPF project.
EnableRecovery.bat
@echo off
rem Check the current recovery status
echo Check the current recovery status...
reagentc /info
rem Enabling Windows Recovery Environment
echo Enabling Windows Recovery Environment..
reagentc /enable
rem Check the recovery status again to confirm it is enabled
echo Check the recovery status again to confirm it is enabled...
reagentc /info
echo Finish.
pause
Click EnableRecovery.bat and set its properties.
Run the WPF program.
Enter the command reagentc /info in the Command Prompt, and you could see Windows RE status of Recovery : Enabled.

Hello @Hongrui Yu-MSFT thanks so much for your code. Still not working i.e. recovery is not enabled.
Before launching the app i set reagenc /disabled, then i launched the app normally or right click as admin, then i verified in the cmd reagentc /info: recovery status is disabled.
Any other idea? thanks

@Hongrui Yu-MSFT Is UAC should be disabled ? Do i need to set anything in the registry or in the GPEDIT to enable the recovery via C#? Thanks

if ru the exe wpf app: i get the folliwng result not good:
Hi,@Kran2022.
Disabling User Account Control (UAC) could make it easier for some applications to run, but it could also make your system less secure. Generally, it is recommended not to disable UAC unless you have a specific need. Here you could try.
1.Open the Start menu and search for "UAC".
2.Select "Change User Account Control settings".
3.Drag the slider to the "Never notify" position.
4.Click "OK" to save the setting.
@Hongrui Yu-MSFT Thanks, infact i tried with both Never Notify & Always notify same results. Also i deactivated 'Real time proetction' off from 'virus " threat protection settings, still same result.
Is there anything blocking in the system.
When we launch the batch file alone it works, but when we launch the bat via another app, its not working. I dont understand.
thansk for your help.
@Hongrui Yu-MSFT is there anything i need to verify or change?

Hi,@Kran2022.
You could try:
EnableRecovery.bat file in the WPF code I provided to ensure that the process has indeed executed the EnableRecovery.bat fileException e to catch the exception and check the execution status of the processcatch (Exception e)
{
MessageBox.Show(e.Message);
}
@Hongrui Yu-MSFT Thanks. Still no error message, no changes, may be i'm missing somehting in the system.
