Known issues in this update

Symptom Workaround
After installing this 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.| 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 installed updates released June 8, 2021 or later.
