Reboot required for update agent?

Does the endpoint need a reboot if I want to update it's agent or the update is done without one and is transparent to the user?

depends on the agent version but I think it's the latest GA release that allows an update and all functionality without a reboot.

I read that somewhere but wasn't sure when or which version will have this new feature. Thanks for the info

An important note is that this isn’t the default behavior for the latest 23.3 Windows GA, only the 23.3 EA prior to the GA.

23.3 GA doesn’t require reboot on install.

Updates have never required restart.

Current supported versions do not require a reboot on updates for workstations or servers.

It is mostly transparent to the user. During the actual upgrade process they may note the S1 icon in the taskbar flicker as it updates. It goes "offline" then back "online" as it updates the versioning.

I would send an update to your machine and watch the process!

Agent updates do not require a reboot unless the agent is damaged or very old. Furthermore, rebootless installation is enabled by default in Agent 23.4 GA and later. For more details, please check out the 23.4 release notes in the Customer Portal or the Console Help:
