Hello Charles,
Thank you for your post.
The Host shouldn't freeze in the first place. There were a couple of small issues that we fixed. These issues could cause the Host to freeze in some rare occasions.
As for changing the recovery options this way - it is not recommended to directly edit the service properties this way. This might cause erratic behavior in the future.
What I recommend you to do for now is completely removing the Host (including its settings from the registry,
here is a guide) and re-installing.
