Exchange Server February SU fails: setup says processes are in use even after reboot & maintenance mode

u/maxcoder88 You should remove MSMQ from your system, as it is not needed by Exchange Server. You can run the following to remove it:

`Remove-WindowsFeature NET-WCF-MSMQ-Activation45, MSMQ`

See [https://learn.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites](https://learn.microsoft.com/en-us/exchange/plan-and-deploy/prerequisites) for details.

Then, reboot the server and try installing the SU again.
