Looks like this is still needed unfortunately.
This script just puts in a simple service that checks every 5min if the agent service is running.
If not, it will fire it back up again. 5min should me more than enough for agent updates to take place without causing any problems.
But like all scripts posted here, use at your own risk.

If you want you can host the app on your own server, just change line 26 to match the new location.

The script only needs to be run once, so just set it as manual and trigger it.
The service runs in the background and will do the rest.

As always, if you would like to buy me a beer you can do so using this link.
