After installing KB5003637 or later updates, apps accessing event logs on remote devices might be unable to connect. This issue might occur if the local or remote has not yet installed updates released June 8, 2021 or later. Affected apps are using certain legacy Event Logging APIs. You might receive an error when attempting to connect, for example:
  • error 5: access is denied
  • error 1764: The requested operation is not supported.
  • System.InvalidOperationException,Microsoft.PowerShell.Commands.GetEventLogCommand
  • Windows has not provided an error code.
Note Event Viewer and other apps using current non-legacy APIs to access event logs should not be affected.

Affected platforms:
  • Client: Windows 10, version 21H1; Windows 10, version 20H2; Windows 10, version 2004; Windows 10, version 1909; Windows 10, version 1809; Windows 10 Enterprise LTSC 2019; Windows 10 Enterprise LTSC 2016; Windows 10 Enterprise 2015 LTSB; Windows 8.1; Windows 7 SP1
  • Server: Windows Server, version 20H2; Windows Server, version 2004; Windows Server, version 1909; Windows Server, version 1809; Windows Server 2019; Windows Server 2016; Windows Server 2012 R2; Windows Server 2012; Windows Server 2008 R2 SP1; Windows Server 2008 SP2
Resolution: This is expected due to security hardening changes relating to Event Tracing for Windows (ETW) for CVE-2021-31958. This issue is resolved if the local and remote devices both have KB5003637 installed.
