How do I completely disable "Check for Updates"?

The Check for Updates feature can be disabled by changing the registry string value NoUpdateChecking from 0 to 1 in HKEY_CURRENT_USER\Software\Nico Mak Computing\WinZip\UpdateCheck

If the same string value change is made in HKEY_LOCAL_MACHINE it will propagate to any new user profiles that may be later added to the same computer.
