If you have a computer that is running Windows 7 or Windows Server 2008 R2; and if occasionally, the computer crashes after it runs for some time, with a Stop error message on a blue screen, then you may want to apply this hotfix from Microsoft.
![]()
The Stop error message resembles the following:
STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4) IRQL_NOT_LESS_OR_EQUAL
This issue occurs because Power Manager opens an Advanced local procedure call (ALPC) port. However, Power Manager closes another port instead of closing the ALPC port.
Every time that a power request is made, a memory leak occurs. When the leaked memory usage accumulates to a certain level, the computer crashes.
