This update (KB3009676) contains all the fixes for KB3008242. If you install KB3008242 and then install this update, you will see the version number of PDC.sys drop on your system. The drop in the version number of PDC.sys should not cause alarm.Â
Symptoms
Consider the following scenario:
-
You have a device that is running Windows 8.1 and that has a Secure Digital Input Output (SDIO) Wi-Fi driver installed.
-
The device has updates 2919355 and 2883200 installed.
-
You restart the device (warm boot).
-
You put the device in idle for about one minute.
-
You perform one of the following steps:
-
Put the device in hibernation, and then resume the device.
-
Enter Connected Standby, and then resume the device.
-
Disable and then re-enable Wi-Fi.
-
In this scenario, the clock frequency of the SD bus decreases to about half of the usual rate. This may decrease performance on a Wi-Fi network connection.
