Microsoft requires security vendors to sign binaries using Azure Code Signing (ACS). As a result, applying a minimal Microsoft Windows update based on the version of Windows is required. Therefore, customers who do not have the minimum OS build/patch of Microsoft Windows after February 18, 2023 may encounter the following errors:

- Agent Program and Services may not work properly.
- There will be a reporting issue between the Windows Security Center (WSC) and the security agent which could result to the agent co-existing with Windows Defender. This could possibly lead to slow login, application lockup, or machine unresponsiveness.

Microsoft's official KB with additional information on this can be found [here (KB5022661)](https://support.microsoft.com/en-us/topic/kb5022661-windows-support-for-the-azure-code-signing-program-4b505a31-fa1e-4ea6-85dd-6630229e8ef4).
