According to the release notes for VSE8.8 Patch 7, there is a recommendation for the client system to be rebooted after the patch has been deployed.
For servers we have to do this in a controlled manner as we can't risk 130+ servers spontaneously rebooting.
For example, we may deploy the patch via ePO today with a view to rebooting the server estate during the next Windows patch cycle which could be in a few weeks time.
What is the implication of not immediately rebooting a client system once Patch 7 has been deployed? Will the patch be effective? Will VSE continue to function as normal?
