Microsoft patches Windows and Excel – breaks audio, remote access, and paste

Microsoft released a batch of patches for Windows and Excel that have caused issues with audio playback, remote access, and pasting data. The patches, which were released on September 14, 2026, address several security vulnerabilities, including one that could allow an attacker to execute arbitrary code on a system. However, the patches have been criticized for breaking audio playback in some applications, including Microsoft's own Teams and Edge browsers. Additionally, the patches have caused issues with remote access to systems, making it difficult for users to access their computers remotely. The patches have also caused problems with pasting data, including Excel spreadsheets, which can now cause the program to crash.
