Problems with KB4540673 are getting worse. In a new report, Windows Latest states that multiple users are now facing audio problems (particularly with older sound cards) and uninstalling the update, rolling back to an older version of Windows and reinstalling drivers does not fix it. In addition to this, KB4540673 is resulting in a user profile bug which causes Windows 10 to load a temporary user profile when booting up.

Users have been able to log back into their original profiles and remove the temporary account, but it’s an irritating fault which also has a depressing sense of deja vu. Beyond these, there are also isolated cases of Internet connectivity problems, freezes and app crashes being reported. Back to the drawing board with this one, Microsoft.
Important additional update news today (via BleepingComputer) with Microsoft announcing it has patched a critical Windows 10 vulnerability in Microsoft Server Message Block 3.1.1 (SMBv3). The update – KB4551762 – patches “a network communication protocol issue that provides shared access to files, printers, and serial ports.” It is rolling out to Windows Update now but can also be manually installed via the Microsoft Update Catalog.
“We recommend that you apply this update to your affected devices with priority,” states Microsoft with the company noting that no real world exploits have been developed, though with the problem now out in the open that will be only a matter of time.
The exploit, known as SMBGhost or EternalDarkness, affects 1903 and 1909 versions of Windows 10 and Windows Server. Edit: following the Bleeping Computer report, there is an excellent analysis of the problem from Davey Winder here.
