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).
