Intune Windows 11 KB5021234 KB5021255 Deployment
Let’s check how to deploy the Windows 11 KB December 2022 Patch Tuesday (LCU) Deployment using Intune. You can deploy Windows 11 December CU using Microsoft Intune. The patch deployment process in Microsoft Intune is different from that of SCCM.
I don’t think creating a new patch deployment policy to cater to monthly CU deployments for Windows 11 is mandatory, but you can use the following method to expedite. The existing patch deployment policy will deliver the patches using WUfB (Windows Update for Business).
You can expedite the Installation of December 2022 quality updates if the device OS version is less than 2022.12. Create expedited update profiles for Quality updates using the following steps.
- Sign in to the Microsoft Intune admin center https://endpoint.microsoft.com/
- Navigate Device -> Windows 10 quality Updates (preview).
- Click on + Create Profile.
The following are the Settings for Intune quality update profile for the Windows 11 monthly patching process if you want to expedite the deployment of patches. Otherwise, you can use the standard quality updates policy from Intune.
- Name – Windows 11 December 2022 LCU
- Description— I would recommend adding a detailed description.
- Expedite installation of quality updates if the device OS version is less than 13th December 2022 – 2022.12 B Security Updates for Windows 10 and later
- Number of days to wait before the restart is enforced – 1 Day
