    How To Avoid System Hang,Freeze,Memory Leaks In Windows 7-Bug Fixed

     Many Windows 7, Windows Server 2008 and Windows Vista Users face some odd issues that are occurring sometimes in their system.These bugs are not typically fixed via Windows Update,Instead Microsoft offer Hot fixes which should only be applied to systems experiencing the specific problem. So if you are not affected by any of these problems, you should not apply them, just hang out for a service pack.
    Here are the four most prominent issues, listed in order of decreasing severity.

    1. Computer Crashing with BSOD ( Blue Screen Of Death )

    This first issue occurs when the computer crashes after it runs for some time, with the user seeing the following BSOD (the four parameters vary depending on the computer):

    STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4)
    IRQL_NOT_LESS_OR_EQUAL

    Microsoft explains that the issue occurs because Power Manager opens an Advanced Local Procedure Call (ALPC) port and closes another port instead of closing the ALPC one, resulting in a successive memory leak, leading to an eventual crash. here is the Hotfix provided by Microsoft.

    2. Windows Displays Blank Screen And Mouse Pointer Upon Wake
    While this issue isn’t to problematic, it can be annoying. This only affects laptops and netbooks but also affects Windows 7, Windows Vista, Windows Server 2008 R2, or Windows Server 2008.( KB958685 ) Say you put the computer to sleep while the lid is open and then close it after it has gone to sleep. When you go to wake it up again, Windows resumes but you only see a blank screen and a mouse pointer until you provide some user input such as a keystroke or mouse click. This issue is meant to be addressed in an update soon enough but there is also a Hotfix available here.

    3. When You Use A USB Storage Device It Becomes Unresponsive
    This issue only occurs with Intel 5 and 3400 series chipsets and a copy if either Windows 7 Home Premium, Professional or Ultimate and when the USB device has pending control and bulk traffic. The iPhone is mentioned as a culprit in KB978789 . Basically what happens is the Platform Controller Hub gets all confused and can’t determine which traffic has priority. As a result it stops responding, however this only affects a limited number of USB devices.
    Microsoft don’t have a solution for this issue as of yet and say that you should contact the manufacturer of your Motherboard and get information on how to update your BIOS.

    4. Microsoft Rebound Becomes Unresponsive On A Touchscreen Computer
    This finally issue isn’t exactly a deal breaker but it may affect some of you. It affects all copies of Windows 7 and occurs mainly in Quad core machines with Multi touch. Basically all that happens is the Microsoft Rebound game becomes unresponsive when you try to launch it.Microsoft are at fault here so a hotfix is available from here
