...a Google search for that error message? See the link below for lots of possiblities:
Google Search for "the application failed to initialize because the window station is shutting down"
You might also check to see if other programs conflicts, antivirus, antispyware, etc. are causing the problem with Internet Explorer.
If the error is only showing when closing Internet Explorer, you might also "repair" Internet Explorer. Do it by reinstalling XP Service Pack 2.. If you've got the SP2 CD, then run it again. If you don't, then download the full installer package from the link below. (It's a large download, about 260 MB, so you'll need a broadband connection.)
Hope this helps.
For about the last month or so, I get a message when i'm simply closing out IE that reads......."the application failed to initialize because the window station is shutting down" Upon clicking OK, I get the message...The instruction at "0x5ad71531" referenced memory at "0x00000014" the memory could not be "read" This happens probably 10-20% of the time when I shut down IE.
If I don't immediately acknowledge the error with "ok" then I have to actually unplug the computer to get it to do anything. It will not restart, switch user, or anything at all. It just sits there with a blank screen.
I'm not running any special applications or programs at the time, just simply closing out on IE with the "x"
I'm running XP SP2, 128MB ATI Hyper Memory PCI-Express X16 (DVI/VGA/TV Out) Radeon X300 SE, 1GB DDR2 SDRAM at 533MHz with media center 2005. And it's a Dell XPS 400 if that would make any difference.
