April patch Tuesday focus: Windows and Exchange (again)

On Tuesday, MICROSOFT published another extensive set of updates throughout the Windows ecosystem. This includes four publicly available Windows vulnerabilities and one security flaw that affects the Windows kernel (which has already been reported to be exploited). That is, Windows Update gets the highest “patch now” rating. Keep in mind that if you need to manage an Exchange server, you will need additional privileges and additional steps to complete the update.

It also looks like Microsoft has announced a new way to deploy updates to devices wherever they are. Windows Update for Business Services.. Learn more about this cloud-based management service. Microsoft video Or This FAQ.. I’m includedUseful infographic This month it looks a bit biased (again) because we need to pay all attention to the components of Windows and Exchange.

Key test scenarios

For this month’s major update of Disk Management Utility (which is considered high risk), it is recommended to test partition formatting and partition expansion. This month’s update also includes changes to the following low-risk Windows components:

  • Verify that the Windows codec changes render TIFF, RAW, and EMF files correctly.
  • Test the VPN connection.
  • Test the creation of a virtual machine (VM) and the application of snapshots.
  • Test the creation and use of VHD files.
  • Make sure that all applications that rely on the Microsoft Speech API work as expected.

The Windows service stack (including Windows Update and MSI installer) was updated this month as follows: CVE-2021-28437Therefore, for large-scale deployments, your application portfolio can include installation, update, self-healing, and repair feature testing.

Known issues

Every month, Microsoft publishes a list of known operating system and platform-related issues included in this update cycle. We have referred to some important issues related to the latest build of Microsoft, including:
