I have a PC that more often than not leaves a blank blue screen after logging on. Task manager works to enable a normal shutdown. I have used msconfig to disable all software and am now working through the services. There is one called ##Id_String1.6844F930_1628_4223_B5CC_5BB94B879762## which I think may be causing the problem. It seems to be related to Bonjour. I have tried deleting the key from the registry but can't. If I stop and disable it, it is started on the next reboot.
1. Is it required and what does it do ?
2. If is is not, how do I get rid of it ?
