That depends a lot on your situation.
Generally you probably should all Critical Updates as soon as available.
If you have few systems, some wait a few days to see what happens to
everyone else.
I keep my computers clean of viruses, spyware and other malware so I usually
install all Critical Updates on my main computer as soon as they are
available. Other computers usually get the updates later that day or the
next day.
I have never had problems related to Windows Update.
If you are a business or other organization with many computers, it is
normal for those to install the updates on a test computer to see how the
update reacts with the particular hardware and software configuration. If
no issues are noted, install on other computers in a few days.
This obviously works best if the computers are similar in hardware and
software configurations.
As zero day exploits become more of a reality, this process introduces
another danger of unprotected computers and dangerous exploits already out
there.
