Microsoft is on a roll releasing new updates for Windows 10 v1903 and v1903. Just last week Microsoft released the security update KB4577671 and now released the cumulative optional update KB4580386 for both v1909 and v1903 system. Unlike the previous update, this is a non-security update. This means that the update only contains fixes and improvements to Windows and its modules. These fixes include but not limited to the Group Policy module, occasional black screen in Windows Virtual Desktop, general performance issues, Xbox Game Pass, Windows Defender, User Access Control, etc. Put simply, the KB4580386 update has a lot of quality of life improvements and fixes to go along with.
Like with any cumulative update, I recommend you wait at least a week before installing. If there are any bugs in the update, those will be ironed out in that time frame. Along as you did not pause the auto updates feature, the update should be installed automatically. If not, you can trigger the update process by clicking on the "Check for updates" button on the "Settings → Update & Security→ Windows Update" page.
Alternatively, you can also install the update by downloading the KB4580386 offline installer. You can find the download links for the KB4580386 installer download below.
