Intune Windows 10 KB5031356 Deployment
Let’s now check into the procedures for implementing the October 2023 (LCU) Patch Tuesday update through Intune. With the utilization of Microsoft Intune, you possess the capability to roll out the Cumulative Update (CU) for Windows 10 in October. It’s worth highlighting that the process of deploying patches via Intune varies from that employed by SCCM (Microsoft Configuration Manager).

You have the option to expedite the Installation of October 2023 quality updates. Create expedited update profiles for Quality updates using the following steps.
- Login into the Microsoft Intune admin center https://intune.microsoft.com/
- Navigate Device -> Quality updates for Windows 10 and later.
- Click on +Create Profile.
The following are the Settings for the Intune quality update profile for the monthly patching process if you want to expedite the deployment of patches. Otherwise, you can use the standard quality updates policy from Intune.

- Description – Recommend adding a detailed description.
- Expedite installation of quality updates if the device OS version is less than 11th October 2023 – 2023.10 B Security Updates for Windows 10 and later
