SCCM 2303 Release Date


Microsoft released SCCM 2303 on April 12, 2023. The 2303 version of SCCM is also available as a baseline version. When installing a new site, Configuration Manager 2303 is also be available as a baseline version. If you are installing SCCM 2303 in production, you can use the baseline installation media.

To download ConfigMgr 2303 baseline media, visit Microsoft Evaluation Center. You can directly access the Configuration Manager current branch download section to get ConfigMgr downloads.

Apart from Microsoft Evaluation Center, you can download the baseline version for ConfigMgr version 2303 from MSDN (Visual Studio Subscriptions) and Microsoft VLSC (Volume Licensing Service Center).

Important: You cannot upgrade to SCCM version 2303 if you are running older versions of ConfigMgr, such as SCCM 2012 or SCCM 2012 R2. If you are still running an older version of Configuration Manager, you must upgrade to the current branch soon.

If you are running Configuration Manager version 2203, you can directly upgrade to version 2303. In other words, you can skip the ConfigMgr 2211 upgrade and directly upgrade to version 2303.

2 Best Solutions: Error Can’t Connect to Windows 365

In this article, I will show you how to resolve the error can’t connect to Windows 365. If you are unable to access your Cloud PC using the Windows 365 app, there are two ways to solve this issue. I normally connect to my Cloud PC using the Windows 365 app. Note that there are multiple ways to connect and access your Cloud PCs.
