Windows 10 October 2018 Update has been one of the worst releases we have seen since the launch of Windows 10 in 2015. The latest edition has gone through a number of upgrade blocks but it looks like Microsoft is finally getting a handle on things. The company has issued an out of bands cumulative update bringing several fixes to Windows 10 1809. Microsoft had also rolled out a cumulative update for the Anniversary Update last night.

There are still some known issues, including Windows Media Player bug and a Microsoft Edge issue. You can install Windows 10 1809 cumulative update automatically through Settings > Update & Security > Windows Update > Check for updates. Or, you can manually download and install the latest cumulative update from Microsoft Update Catalog website.
