Not me. I've been burned by too many updates in the past (not just Microsoft and not just on Windows), so I never ever ever enable automatic updates on anything except anti-virus definitions. Also I generally don't let anti-virus programs remove viruses automatically unless that particular anti-virus program is known to have no false positives.
Sometimes automatic updates cannot be turned off, however, and that leads to baaaad things happening. (IOBit SmartDefrag turning into malware and Readers Hub on Android removing it's only relevant functionality).
This patch fubar perfectly explains why I don't update Microsoft Windows automatically and why I don't immediately install updates, even though the sky supposedly will fall if I don't due to all the evil hackers on the net.
