The Case of the Process Startup Delays

Hi,

I faced the same delays in Windows XP. It takes 5-6 seconds to open any app from run dialog.

Does this explanation fits there too?

Thanks

Hi Mark!

I tried to reproduce your debugging steps on my own laptop, but I stumbled on a problem early on.

You said that you started by attaching Windbg to PROCESS EXPLORER and then you launched Notepad with PROCESS EXPLORER's Run dialog.

If I attach Windbg to PROCESS EXPLORER, the PE window is frozen and I have no access to its file/run dialog.

On the other hand if I attach Windbg to WINDOWS EXPLORER, PE window is not frozen and I can open notepad from its file/run dialog.

Also the PID number (3460) which appears in you first Windbg's Calls window picture makes me think that Windbg was attached to WINDOWS EXPLORER rather than to PROCESS EXPLORER.

Could you please confirm which process Windbg was attached to in your first debugging step?

Thanks

Broken Link for autorun

Link in blog aritcle:

http://www.sysinternals.com/utilities/autoruns.html

Correct Link for autorun utility (as of 7.23.2007):

http://www.microsoft.com/technet/sysinternals/ProcessesAndThreads/Autoruns.mspx

btw Thanks for all the Great SysInternals Utilities - I have Process Explorer set to startup all the time. I just wish there was a GUI shell that provide a mouse drive way to run all the PsTools cmd line utilities. Piping to text files all the time is a bit tedious..

It's extremely interesting, educational & impressive for me (without programming background) to read how Mark gets to the bottom of the inner workings and shortcomings of Windows. I think Mark explains some complex points very effectively (even I understand a lot of it). A beginners guide to the basics, if there are any basics!, of the Windows kernel would be great from Marks perspective.

I hope working at Microsoft won't stop Mark from discussing the bugs in these OS's to the general public. Great articles, very dedicated.

Thanks for the great article! Too bad they appear very rarely though..

If you fancy doing some more digging, I find that whenever compiling with Visual Studio 2003 it causes windows in other unrelated apps to just lock up - e.g. Outlook, Explorer, IE won't repaint properly and appear to be hung. Sometimes, briefly, Explorer windows get the Visual Studio title. Deeply odd! The CPU isn't maxed out by any means. Is there some sort of 'global UI mutex' that MS products use in some way that Visual Studio used badly?

FYI, the reason this only affects Windows 2003 and not Windows XP is to do with the RPC_SECURITY_QOS_V3 structure introduced with Windows 2003 that adds a Sid field: http://msdn2.microsoft.com/en-us/library/aa378649.aspx
