Quote:Just after releasing out-of-band optional updates for supported Windows 10 versions, Microsoft has released additional preview updates for Windows 10 versions 1809, 1903, and 1909. However, unlike the earlier updates that fixed issues with Kerberos authentication – which could only be manually downloaded –, these updates will be offered through Windows Update as optional updates.
 
There are a bunch of bug fixes, with highlights including fixes for an issue with USB 3.0 hubs malfunctioning after a restart. There are also fixes for a bug that causes the Edge browser to launch in the background when users are in tablet mode.
 
Users on Windows 10 version 1909 and 1903 should receive KB4586819, bringing builds 18362.1237 and 18363.1237, respectively. The update will be made available through Windows Update as an optional update and can be downloaded manually from here.
 
Here are the highlights from this update:

Quote:

• Updates an issue that causes the Chromium-based Microsoft Edge browser to open in the background when a device is in tablet mode.
  
• Updates an issue that causes Narrator to stop responding after you unlock a device if Narrator was in use before you locked the device.
  
• Updates an issue with USB 3.0 hubs. A device connected to the hub might stop working when you set the device to hibernate or restart the device.
  
• Updates an issue that might cause games that use spatial audio to stop working.
  
• Updates the visual quality of Windows Mixed Reality headsets that run in lower resolution mode.
