Microsoft just released a brand new batch of cumulative updates for those Windows 10 versions except for the May 2019 Update (also called version 1903).
Since they don’t land on a Patch Tuesday, there are no security improvements during these updates, and also the focus is entirely on fixing bugs and refining the performance of Windows 10.
All updates, however, have a single change mentioned within the release notes, albeit more undisclosed improvements could also be introduced. According to the software giant, the June 26 cumulative updates resolves an issue breaking down the big event Viewer. This can be a bug which was introduced by the prior batch of cumulative updates for Windows 10.
“Addresses an issue that may prevent devices from connecting with a Storage Area Network (SAN) devices using Internet Small Computer Interface (iSCSI) after installing KB4499147. You may also get an error in the System log portion of Event Viewer with Event ID 43 from iScsiPrt along with a description of “Target failed to respond in time for a login request.”
