A new Microsoft update designed to help customers running Windows 7 and Windows Server 2008 R2, including Windows 7 SP1 and Windows Server 2008 R2 SP1, facing an issue in which driver refreshes served to the operating system fail to install is now released.
Microsoft explains, "Consider the following scenario: you try to install a Windows Update package that is marked as Important on a computer that is running Windows 7 or Windows Server 2008 R2."
"The package contains a driver. For example, the package contains the USBport.sys driver. The computer is configured to install updates automatically or during the shutdown process."
"In this scenario, the installation process stops at zero percent for five minutes and then fails with a time-out error," the software gaint explained in KB2552343.
Microsoft also noted that customers are more likely to experience this glitch in two scenarios. It appears that slower computers are affected to a larger degree compared to faster machines, and also that PCs with many devices attached at the time of the update are also impacted more.
The source of the problem has already been identified, with the company explaining that: "This issue occurs because of a race condition in the Plug and Play service during the driver update process."
