The latest cumulative update for Windows 10, KB5051974, has arrived for versions 22H2 and 21H2, bringing essential security updates and addressing a critical memory leak. However, this update also includes the new Outlook for Windows app, as reported by Bleeping Computer.
This update is mandatory due to the inclusion of the January 2025 Patch Tuesday security updates. Users will notice the new Outlook app icon alongside the classic version in the Start Menu after installation. The new and classic Outlook apps can run concurrently, eliminating any disruption to existing workflows.
Beyond the new Outlook app, KB5051974 tackles several other issues. Notably, it fixes a problem affecting the Snipping Tool and Capture Service, where specific keyboard shortcuts used with Narrator active caused these tools to malfunction. In total, this update brings eleven changes and fixes, including:
- Resolution of the “This device cannot start” (code 10) error that occurred after installing the January 2025 security update.
- Prevention of Bing automatically suggesting search engines like Baidu in the search box.
- Improved functionality of USB audio devices when used with a digital-to-analog converter (DAC).
- Corrected USB camera recognition issues upon power-on.
- A fix for the virtual memory leak that could lead to application crashes.
While the numerous fixes in the Windows 10 update are welcome, the mandatory inclusion of the new Outlook app may draw criticism. However, this move becomes understandable given the impending April 2026 end-of-life date for the classic Outlook application.
The update addresses a range of issues impacting user experience and system stability. From resolving USB device problems and memory leaks to improving the functionality of essential tools like the Snipping Tool, KB5051974 offers important enhancements. The inclusion of the new Outlook app, while potentially controversial, prepares users for the eventual transition away from the classic version.
This mandatory update ensures Windows 10 users benefit from the latest security patches and a more stable system performance. While the new Outlook app’s arrival might be unexpected, it underscores Microsoft’s commitment to modernizing its software suite and preparing users for future changes.
