Microsoft has released the May 2023 optional cumulative update for Windows 11, version 21H2, with fixes for audio and printer install problems.
KB5026436 is a monthly non-security preview release designed to enable Windows administrators to test improvements that will be incorporated in the upcoming June 2023 Patch Tuesday release.
According to Microsoft, it addresses a problem encountered by some printers during installation when they connect to Wi-Fi automatically.
The update also fixes an audio playback issue that occurs only on devices equipped with specific processors and a Message Block (SMB) issue preventing users from accessing SMB shared folders because of "Not enough memory resources" or "Insufficient system resources."
It's also important to note that this monthly "C" update is optional and, unlike Patch Tuesday releases, does not include any security-related fixes.
To install
KB5026436, users can either navigate to Settings > Windows Update, where they will find the 'Download and install' button after checking for updates.
You can also download the update from the
Microsoft Update Catalog and install it manually.
