What are New and Fixes in Windows 10 KB5008876?

On January 11, 2022, Microsoft released KB5008876 Cumulative Update for .NET Framework 3.5 and 4.8 for Windows 10 Version 20H2, Windows Server Version 20H2, Windows 10 Version 21H1, and Windows 10 Version 21H2.

• KB5008876 addresses an issue where an attack by an unauthenticated user could result in DOS on the affected system.
• The patch also attempts to fix an issue where WPF would sometimes not respond to touch. This can happen if the WPF window was activated by a touch operation, such as in the case of sliding a listbox.
• This patch also provides solutions for issues involving display flickering, tearing, or incorrect compositing under high GPU load.
• KB5008882 also brings a potential solution to another problem. Earlier, the extra information associated with the WM_KEYDOWN message was sometimes discarded before the handler for the PreviewKeyDown or KeyDown event could retrieve it via GetMessageExtraInfo.
• It fixes an issue where FindAll or AutomationElement.FindFirst would not search subtrees for hands whose UIA_WindowVisibilityOverridden property had been set to 1.
• Another issue this patch attempts to address is the inclusion of bindings on TextBox.Text, where UpdateSourceTrigger=PropertyChanged ends up giving incorrect results when using the Microsoft Quick IME.
• There are also some improvements to SQL connectivity. If a NullReferenceException is thrown while loading a SqlParameter value with the help of a client-provided delegate causing some error, it may prevent the SqlClient driver from cleaning up the state of the connection state. The end result will be an unexpected failure on the connection. It’s important to point out that if you recognize this situation, you can enable the AppContext switch “Switch.System.Data.SqlClient.CleanupParserOnAllFailures” to clean up any kind of failed connections.
• Finally, it also provides some improvements to unsuccessful requests not properly timing out when making asynchronous WCF calls over HTTP.
