Explorer.exe process does not end properly and does not honor the "multiple processes

Hello, we have 2 computer configurations with slightly different problems.

Computer 1

Windows 7 Home Premium x64
Intel i7 920
ASUS P6T
6 gigabytes of DDR3 RAM
Geforce 8800GT[/code]

Computer 2

Windows 7 Home Premium x86
Intel Core 2 DUO e6750
ASUS P5KC
2 gigabytes of DDR2 RAM
Geforce 6600gt

"Launch folder windows in a separate process." was tested in both an enabled and disabled state on both configurations.


On the x64 computer, there is never more then 2 Explorer.exe processes present, each Windows Explorer window will combine with a 2nd Explorer.exe process. When I close a Windows Explorer window, the resources/process for it is not ended/closed properly leaving the application hanging (according to Task Manager) for about 20 to 30 seconds before it silently ends.


On the x86 computer, no matter what the "Launch folder windows in a separate process." is set to, each Windows Explorer window will create a new Explorer.exe process. When I close a Windows Explorer window, the resources/process for it is not ended/closed properly leaving the application hanging (according to Task Manager) for about 20 to 30 seconds (I need a stop watch >.>) before it silently ends.




My question is, how do I debug the cause of these issues? closing startup processes yields no results.
