Microsoft has released a new Cumulative Update for Windows 10 1809 October 2018 Update.
Unlike previously, Microsoft is releasing Cumulative Update KB4476976 only to the Release Preview Ring, taking the OS to Windows 10 v1809 RP Build 17763.288.
The changelog appears to be related to Action Centre fixes, listing the following improvements.
- We fixed an issue where the Action Centre might suddenly appear on the opposite side of the screen before appearing on the correct side.
- We fixed an issue resulting in the Action Centre icon sometimes showing a number of unread notifications, however when you opened the Action Centre it would be blank.
Windows 10 users in the Release Preview Ring can download the update by Checking for Updates in Settings.
