After the latest windows updates we have had not stop problems with pc's hanging on start up. From update Cumulative Security Update for Internet Explorer 8 for Windows 7 for x64-based Systems (KB2647516) through to Update for Windows 7 for x64-based Systems (KB2640148) We have all tried to install at the same time and even if we get onto the pc as an admin user and get them loaded successfully, it works fine when the user logs in, but the next day when they login it hangs again. We have to login as admin then leave for about 15 until the timer stops running then they can login and it works. We have had to do this to one pc 6 times.

Hi, As the issue occurred after installing the latest updates, I suggest performing System Restorefirst. Then, use one computer try to install the updates manually one by one. If the issue appears again, please let me know the KB number of it and uploadthe windowsupdate.log file from C:\Windows\. We will look into it and try to find the culprit.
