Release Date:

May 23, 2019

Version:

Preview of Monthly Rollup

Starting with KB4493472 Monthly Rollup updates will no longer include PciClearStaleCache.exe. This installation utility addressees inconsistencies in the internal PCI cache. This can cause the symptoms listed below when installing monthly updates that do NOT include PciClearStaleCache:

Existing NIC definitions in control panel networks may be replaced with a new Ethernet Network Interface Card (NIC) but with default settings. Any custom settings on the previously NIC persist in the registry but were unused.
Static IP address settings were lost on network interfaces.
Wi-Fi profile settings were not displayed in the network flyout.
WIFI network adapters were disabled

These symptoms are especially common on guest virtual machines and on machines which have not been updated since March, 2018.

Administrators should ensure that any one or more of the Monthly rollups released between April 10, 2018 (KB4093118) and March 12, 2019 (KB4489878) have been installed prior to installing April 2019 and later updates. Each of these rollup updates includes PciClearStaleCache.exe.
