Symptoms


You may experience a delay during boot after installing MS12-074.

Cause


This can occur if an auto-start service makes a web service call during its start routine. 

Resolution


Set the start type of the WinHTTP Web Proxy Auto-Discovery Service to automatic (the default is Manual) using the Services MMC snap-in or sc.exe.

More Information


When an auto-start service makes a call to a demand-start service, the demand start service will be blocked until the SCM times out waiting for the auto-start services to complete starting.
