Basically, when a users logs in to windows 7 and open any application, the computer freezes. If you restart your computer a few times then it works fine. The network printers were pushed through the group policy and it was taking ages for users to login. So, we removed the policy and added the printers manually. Ever since, the users login time reduced but the print spooler service is causing the problem. When you click on Devices and Printer, the load bar keeps on moving but nothing happens, you can't see the printers. If you delete the printer connections from registry and restart your computer then it works fine. We re-add the printers and it works fine until we restart the computer. So, on restart the same problem to occur again.
Any suggestions? Is there is windows update causing this issue?
