  • Get-ExchangeServer | Format-List Name, Edition, AdminDisplayVersion

2. Visit the link below, and download the desired Exchange 2013/2016 update:

3. Before running the installer, ensure you have read and understand the release notes, system requirements and prerequisites. Once ready, proceed to the update wizard. 4. After you install a cumulative update or service pack, you must restart the computer so changes can be made to the registry and operating system.
