Hello Hichem SGHAIER
Windows Update policies are a way to manage updates for Windows devices, and it helps admins control the timing, frequency, and type of updates. Note that changing the update policy can affect the update behavior of your device, so it's recommended that you back up your device before making changes.
You need to have an administrative account to do this. Here are the steps to disable configured update policies:
Press Win + R keys to open the Run command box and type gpedit.msc and click OK. This will open the Local Group Policy Editor.
Navigate to Computer Configuration > Administrative Templates > Windows Components > Windows Update.
Double-click on any of the policies that you want to disable and select Not Configured. Then click Apply and OK.
Repeat this for the policies that you want to disable.
Best Regards
