KB2685811 x64 is an update for Kernel-Mode Driver Framework (KMDF) version 1.11 for Windows 7 for x64-based systems. KMDF is a component of Windows that supports user-mode drivers that are written specifically for KMDF. User-mode drivers are drivers that run in user mode, which means they have less access to system resources and are more isolated from other drivers and applications. This makes them more secure, reliable, and easier to debug than kernel-mode drivers, which run in kernel mode and have full access to system resources.
By updating KMDF to version 1.11, you can benefit from the latest features and improvements that Microsoft has made to user-mode driver development and support. For example, KMDF 1.11 supports dynamic enumeration of devices, which means that devices can be added or removed without restarting the system. It also supports power management features, such as idle detection and wake-up capabilities, which can help reduce power consumption and extend battery life. Additionally, KMDF 1.11 provides better compatibility and interoperability with other components of Windows, such as User-Mode Driver Framework (UMDF), Windows Driver Framework (WDF), and Windows Hardware Certification Kit (WHCK).
If you have devices or applications that use user-mode drivers that are based on KMDF, you may need to install KB2685811 x64 to ensure that they work properly and efficiently on your system. Some examples of devices or applications that use user-mode drivers are USB devices, Bluetooth devices, webcams, printers, scanners, smart cards, biometric devices, audio devices, sensors, touchscreens, and virtualization software.
