Question about Windows update

Hey guys ! So basically I have 2 questions about all the automatic windows 10 updates.

Because windows often updated my system without any notice, and then at the morning, Instead of starting working I needed to wait 30-40 min for windows to update I disabled "windows update" service, as probably most people at this point.

1. Is it a good way to prevent windows 10 from automatically updating, or is it harmful in a long run ?
2. If you guys think that some of the updates are still important and they should be installed, how often should I manually enable the service and update my system ?
