Please try using the Remote Install tool as a workaround and an alternative to Simple update. In this tool, the upgrade process uses a slightly different approach, so it should help override the problem with the restart manager. The update issue was fixed in the current version 184.108.40.206, but unfortunately, it will not work retrospectively. The new process will start to apply when updating Hosts version 220.127.116.11 (i.e. the now current version) and later.
This is a known issue and this is not an issue specifically with the simple update. For some reason, Windows Restart Manager (which may act as part of the msi installation procedure) fails to restart Remote Utilities Host service after the update.
We couldn't figure out exactly why this happens - there were few customers who reported this and we couldn't find a pattern, the issue happened quite randomly. We decided that we would rather completely re-write the update process to make sure the updater takes complete control over the process instead of delegating it to Microsoft's msiexec and the system. So we implemented this change in the current version (18.104.22.168).
This fix has one downside though - unfortunately, it will not work retrospectively. The new process will start to apply when updating Hosts version 22.214.171.124 (i.e. the now current version) and later.

Please try to customize hotkeys the Viewer uses. To change hotkeys: 1. Open the main Viewer window and navigate to the tab Tools -> Options. 2. In the Options window switch to the Hotkeys tab. 3. Specify a custom hotkey for Ctrl+Alt+Del.
Not to mention that this "feature" blocks the taskbar, so you're often prevented from fixing whatever problem you needed to fix remotely in the first place.
As I mentioned earlier, the notification is informational and shown only once. It doesn't prevent you from establishing a connection and can be closed by a remote user. That message is necessary to let the user know that the program was installed and to prevent the rogue activities out-of-the-box. Remote users must always know that they are being monitored or are about to be monitored.
