Just two days after the last one...

Microsoft has released another update for its latest Windows 10 October 2018 Update aka version 1809. Just two days ago, the company had already delivered April’s second batch of cumulative updates. While definitely a rare occurrence, today’s update does bring a very long list of fixes and performance improvements to version 1809. It also includes all the fixes that had been delivered via Wednesday’s Build 17763.439 (KB4501835).
