Microsoft Releases Update to Fix Unexpected Shutdown or Blue Screens While Using USB Video Device in Windows 7

Microsoft has released a new update for Windows 7 and Server 2008 R2 users.

You should install this update to prevent unexpected shutdowns or bluescreens when you are using a USB video device. After you install this item, you may have to restart your computer.


On a computer that is running Windows 7 or Windows Server 2008 R2, you may receive one of the following Stop error messages:

Stop 0x0000007E (parameter1, parameter2, parameter3, parameter 4)

Stop 0x00000050 (parameter1, 0 or 1, parameter 3, 0)

This behavior occurs when you unload a USB video device or when you shutdown the computer.


This issue occurs because of a race condition in the USB Video driver when a USB video device is unloaded.


Download and install the required update using following link:
