[German]On March 8, 2022 (second Tuesday of the month, Patchday at Microsoft), various cumulative updates for the supported Windows 10 builds (from the RTM version to the current version) were released. Here are some details about each of the Patchday security updates.

A list of the updates can be found on this Microsoft website. I have pulled out the details below. Since March 2021, Microsoft has integrated the Servicing Stack Updates (SSUs) for newer Windows 10 builds into the cumulative update.

Updates for Windows 10 Version 20H2-21H2

For the Windows 10 versions mentioned above, Microsoft provides only one update package, which is mentioned below.

Update KB5010342 for Windows 10 Version 20H2 – 21H2

Cumulative update KB5011487 raises the OS build to 19042.1586 for Windows 10 version 20H2, 19043.1586 for Windows 10 version 21H1, and 19044.1586 for Windows 10 version 21H2. The update contains only security fixes, but no new operating system features. It fixes the reset bug described in the articles Microsoft confirms wipe issue on resetting Windows 10/11 (20H2 – 21H2) and Windows 10/11 (21H2): Wipe does not delete user data.

Addresses a known issue that occurs when you attempt to reset a Windows device and its apps have folders that contain reparse data, such as Microsoft OneDrive or Microsoft OneDrive for Business. When you select Remove everything, files that have been downloaded or synced locally from Microsoft OneDrive might not be deleted. Some devices might take up to seven (7) days after you install this update to fully address the issue and prevent files from persisting after a reset. For immediate effect, you can manually trigger Windows Update Troubleshooter using the instructions in Windows Update Troubleshooter.

Microsoft notes that this update makes quality improvements to the servicing stack (is responsible for Microsoft updates). This update is automatically downloaded and installed by Windows Update, but is also available from the Microsoft Update Catalog and via WSUS and WUfB. If the update from May 11, 2021 (KB5003173) or a newer LCU is missing, the special, standalone SSU from August 10, 2021 (KB5005260) must be installed beforehand. For the update, Microsoft states various known issues in the support article. Thus, an RDP connection problem is rolled back via KIR.
