Hi. On 2011-04-17, .NET Framework 3, 3.5 and 4 are updated via Automatic Update/Windows Update. Subsequently, all users (user accounts) experience significant startup delays during which Windows Shell (Explorer.exe) does not respond, especially Taskbar and
Start Menu either do not respond or respond after a delay.
I have confirmed that during the delay, Microsoft .NET Framework NGEN v4.0.30319_X86 service is in Starting state. Disabling this service would temporarily resolve the issue for one single startup. (I believe it is because installed .NET Framework applications
put this service back to work.)
How can I resolve this delay?
P.S. Please don't tell me to .NET Framework forum; that one is a developers forum and I don't want to receive code optimization tips for applications that haven't written myself!
The greatest moment of everyone's life is the moment of positive thinking.
