Updating registry through cmd
Some cumulative updates will include Active Directory schema changes.
In those cases the following steps will be required.
Note: The AD preparation tasks are not required to be run separately to the upgrade of Exchange, unless in circumstances where you need to separate the tasks to different teams with different permissions, or if you have a multi-domain forest and want to control the AD changes.
Before applying the schema update follow the steps provided by Michael B Smith to retrieve the existing Exchange schema version, so that you can compare it before and after the AD preparation steps have been completed to verify that the schema update was applied.
Note that the redirect target server must be provided as a fully qualified domain name.

Power Shell (the console host and the ISE) do not, simply because they were compiled against older versions of . Visual Studio 20, MSBuild, turbotax, and a host of websites, Share Point and so on should not be automigrated.
NET framework loaded systemwide, which will in turn allow Power Shell to use . NET 4.0 applications that call Power Shell using the Power Shell API (System. These are machine-wide keys and forcibily migrate ALL applications to . Many products do not work if forcibily migrated and this is a testing aid and not a production quality mechanism.
Power Shell) just fine, but these steps will help get the in-the-box Power Shell hosts to work under . Please be VERY careful with using the registry key approach.
NET 4 supports running applications built against older versions of the framework, it seems like the simplest solution is to launch Power Shell with the . NET 4 to start only a single instance of Power Shell using version 4 of the CLR.
