Windows 10 version 1903 gets a new optional patch with build 18362.449, here’s what’s new

Microsoft has just released a new optional cumulative update for Windows 10 version 1903. The new build 18362.449 (KB4522355) includes a lot of quality improvements, including fixes for issues preventing Start menu, the Cortana Search bar, Tray icons, or Microsoft Edge to stop responding in certain circumstances.

You can find a summary of the most important fixes below, and the full list is available on Microsoft’s Windows support website:

• Updates an issue that prevents Microsoft Narrator from working in certain touch mode scenarios.
• Updates an issue that starts assistive technology (AT) (such as Microsoft Narrator, Magnifier, or NVDA) after signing in when you’ve configured it to start before signing in.
• Updates an issue that causes Magnifier to stop working in certain scenarios, and you have to restart it manually.
• Updates an issue that causes Microsoft Narrator to stop working in the middle of a session in certain scenarios.
• Updates an issue that might prevent a scroll bar from being selected.
• Updates an issue that allows a device to go to Sleep (S3) even if you configure the device to never sleep.
• Updates an issue that prevents you from shrinking a window in some cases.
• Updates an issue that prevents you from connecting to a virtual private network (VPN).
• Updates an issue that causes screen flickering or is slow to display the screen when you show application thumbnails on a monitor that has high dots per inch (DPI).
• Updates an issue that causes the tile for the Photos app to appear larger than expected in the Start menu under certain conditions.
• Updates an issue that causes the system to stop responding at the sign-in screen.
• Updates an issue that might cause a black screen to appear the first time you sign in after installing a feature or quality update.
• Updates an issue that causes the Start menu, the Cortana Search bar, Tray icons, or Microsoft Edge to stop responding in certain scenarios after installing a monthly update.

This latest optional patch follows the cumulative updates for Windows 10 versions 1809 and 1803 that Microsoft released last week on October 15. Microsoft isn’t aware of any known issues in the build 18362.449, and hopefully the Start Menu bugs that some users have been encountering after installing previous patches have now been fixed for good.
