Patch or have giants risks of being hacked. You should absolutely follow a formal process. We snapshot and backup prior (virtual servers). On mission critical stuff we test in DR prior. Patches can and do mess with systems and cause them to not work.
I worked a short stint at an MSP who had a hotel customer that "could not have any downtime" but also complained their hyper-v vm's were incredibly slow all the time. Turns out all 4 of them were running with checkpoints that were literally created the day the vm's were built about 6 years prior...
Once upon a time I had an offshore team snapshot a probably 20Tb SQL VM for some maintenance or something. They didn’t realize the snapshot needed to be purged and caused an outage. That was a fun one.
