June 20, 2019 - KB4503277 (Preview of Monthly Rollup)

Applies to: Windows 7 Service Pack 1, Windows Server 2008 R2 Service Pack 1

---

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.

Improvements and fixes

This non-security update includes improvements and fixes that were a part of KB4503292 (released June 11, 2019) and also includes these new quality improvements as a preview of the next Monthly Rollup update:

• Addresses an issue that prevents the Calculator application from following the Gannen setting when it is enabled. For more information, see KB4469068.
• Addresses an issue with evaluating the compatibility status of the Windows ecosystem to help ensure application and device compatibility for all updates to Windows.
• Addresses an issue that causes Internet Explorer 11 to stop working when it opens or interacts with Scalable Vector Graphics (SVG) markers, including Power BI line charts with markers.
• Addresses an issue that may display the error, “MMC has detected an error in a snap-in and will unload it.” when you try to expand, view, or create Custom Views in Event Viewer. Additionally, the application may stop responding or close. You may also receive the same error when using Filter Current Log in the Action menu with built-in views or logs.
