SYMPTOMS
Your Microsoft Windows 2000-based server may stop unexpectedly when you switch between program windows. You receive the following Stop error message:

A problem has been detected and Windows has been shut down to prevent damage to your computer...

Technical information:


 * STOP: 0x0000000A

IRQL_NOT_LESS_OR_EQUAL***

Note The four parameters in this message may vary based on the cause of the Stop error.



CAUSE
This problem occurs when you use the ALT+TAB keyboard shortcut to switch between active program windows. When you do this, structures that are in the SWITCHWNDINFO application pool are not removed from memory. Therefore, a memory leak occurs.
