Windows 10 1809 KB4490481: the missing patch arrives, finally
Microsoft released the long awaited second cumulative update of the monthÂ KB4490481 for Windows 10 version 1809 yesterday evening.
Why did it take so long to release when cumulative updates for all other supported versions of Windows 10 arrived on March 20, 2019? Because Microsoft learned from the mistakes it made when it released Windows 10 version 1809 and subsequent updates.
It appears, that Microsoft pushes updates for the current version of Windows 10 to an extra round of testing, courtesy of the release channel, before it releases it to the general population.
Update: Ran into a System Service Exception error on restart after installing the update on one machine. System Restore fixed the issue, Startup repair did not. End
