Microsoft is now testing Windows 10 build 19045.5435 (KB5050081) in the Release Preview Channel of the Windows Insider Program, which includes the new Outlook app and fixes for virtual memory, IME, NFC, USB Print, and screen capture.

According to the official changes, build 19045.5435 for Windows 10 22H2 replaces the Mail app with the new Outlook experience already available on Windows 11.

Also, this update now shows weather information in the calendar. To turn on this option, open Settings > Time & Language and turn on the “Weather” toggle under the “Calendar Events” section. You will also find two on the page, including “Feature holiday & events” and “Holiday illustrations.”

If you can’t find the settings, it’s possible to enable the “Calendar events” section (via @PhantomOfEarth) using the ViveTool and running vivetool /enable /id:51858330,48433719,49453572 command.

In addition, this Windows 10 non-security update fixes various issues with virtual memory, causing apps to fail, and addresses a problem.

When using the Chinese Pinyin input method editor (IME), Bing will stop giving automatic suggestions. This update also fixes a problem preventing NFC from reading cards, addresses print spooler issues with the USB Print and IPP Over USB, and fixes the Capture Service and Snipping Tool to stop responding.

Finally, this release updates the list of drivers at risk for Bring Your Own Vulnerable Driver (BYOVD) attacks.
