Good point about the auto-updates, maybe I'll make it automatically copy the 
shell32.dll from system32 into windows each time I boot to make sure any 
updates are reflected.

Nothing showed up, every shell32.dll was referenced in the system32 folder. 
I don't know what else to try, but at least I have my computer back working 
at a normal speed, even if it is a bit of a hacky temporary fix.

That may be difficult if the DLL is actually being loaded by explorer.exe.

Grasping for straws here, but check that "Windows\system32" comes before  
"Windows" in your %PATH%.

It could also be caused by a crappy shell extension with an import table  
entry for "windows\shell32.dll". That would be a little more tedious to  
track down, though you could come a long way by simply disabling all  
non-essential extensions with ShellExView.

No. Vista added the ability to cancel an outstanding IO request that was 
hanging. XP doesn't have that, so you get a timeout. Known problem fixed 
years ago.

That in part is a kernel/driver problem, since it actually *does* hang the 
whole machine to a large extent.

Shell scripts to the rescue?

SSDP *is* UPnP.

I thought SSDP was what found UPnP devices; so it might freeze because  
it's looking or it might freeze because it's trying to interface with it.  
But yes turning off SSDP should turn off UPnP too.

SSDP is part of uPnP, yes. It's the equivalent of WINS for netbios, tracking 
the announcements.

LOL, my AV software has flagged this as a "hacking tool" :-)

According to SecuROM (or whatever it's called), Process Explorer is a 
"cracker tool", and having it installed prevents Crysis from running.
