SCCM 2403 Hotfix KB28458746

There is a new hotfix KB28458746 available for SCCM version 2403 that fixes a software update deployment issue with Configuration Manager clients. This guide covers the fixes included in the KB28458746 hotfix and describes the process for installing this update.

The Configmgr product team discovered the issues in version 2403 and determined that they occur when Configuration Manager configures the policy “Specify source service for specific classes of Windows Updates” to use Windows Server Update Services. The KB28458746 update prevents Configuration Manager from configuring the policy but doesn’t remove or change any previously configured policy.

It is important to note that KB28458746 is the second hotfix released for SCCM 2403 after the KB28290310 CMG VMSS hotfix. It’s an out-of-band update, and you must use the update registration tool to import hotfixes in the SCCM console. This hotfix doesn’t replace any previously released hotfix.

Installing the KB28458746 update doesn’t require a computer restart or a site reset after installation. However, after installing the hotfix on your primary sites, pre-existing secondary sites must be manually updated. Remember that to apply the KB28458746 hotfix, you must be using Configuration Manager, version 2403.
