Laptop restarts while Sleep

So I noticed MS automatic updates keep updating even if laptop is in Sleep.  I put laptop Sleep every night.  Few times I found it restarted in the morning waiting for my login.
Does it mean Auto-updates work even in Sleep position or were they downloaded with laptop was on and restarting while asleep overnight?
How to prevent this in the future?

The computer won't download anything when sleeping. However, it will wake-up at a predetermined time to apply downloaded updates. Hibernation will not do the same.
