Microsoft Releases Windows 10 Cumulative Updates KB4509479, KB4509478, KB4509477

Microsoft has just released a new batch of cumulative updates for all Windows 10 versions except for the May 2019 Update (also referred to as version 1903).

Since they don’t land on a Patch Tuesday, there are no security improvements in these updates, and the focus is entirely on fixing bugs and refining the performance of Windows 10.

All updates, however, come with a single change mentioned in 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 Event Viewer. This is a bug that was introduced by the previous batch of cumulative updates for Windows 10.

“Addresses an issue that may prevent devices from connecting to some Storage Area Network (SAN) devices using Internet Small Computer System Interface (iSCSI) after installing KB4499147. You may also receive an error in the System log section of Event Viewer with Event ID 43 from iScsiPrt and a description of “Target failed to respond in time for a login request.”
