The Windows 10 cumulative update KB4507453 released by Microsoft on July 9 would have caused a restart notification loop on some of the computers on which it was installed.
This issue has been reported by Windows users on several websites and web-based help desk forums. [1, 2, 3], all describing exactly the same problem – they are asked to reboot their devices again to complete the installation of the KB4507453 update, even if it was already installed.
Although this problem has already affected several users of Windows 10 Version 1903 and Windows Server Version 1903, Microsoft has not yet publicly confirmed the problem with the restart notification loop encountered.
All systems on which KB4507453 is installed are not affected
In addition, according to the German blogger Günter Born, who initially reported the problem of the restart loop, all users of Windows 10 version 1903 who install this cumulative update will not be affected because it does not have been able to reproduce the bug on his test systems.
The update information does not include any information about changes to the Windows 10 notification system or how to install the update that may be behind this issue.
As detailed in the KB4507453 update entry on the Microsoft Product Support Web site, this contains the following features:
Born says that there are at least two possible workarounds for getting rid of irritating alerts continually harassing users so that they restart their systems.
The first is to click the "Restart Now" button in the notification dialog box generated by the Windows 10 Notification Center instead of trying to reboot the system from the Start menu.
A second solution is to search for system updates again via Windows Update, as Jan Schüßler discovered from heise online. This allows the operating system to see that no new updates are available and that no other reboots are necessary since all previous updates have been made. have been installed.
This may also happen only after a certain time once Windows checks for updates itself, although it may take hours for some of the affected Windows users.
More problems caused by July cumulative updates
Other monthly totals, security updates only, and cumulative updates (that is, KB4503293, KB4503327, and KB4503286) released June 11 are causing a problem already confirmed by Redmond. and impacting multiple versions of Windows 10 Server.
This new problem, known and recognized today by Microsoft, can prevent devices from starting if they use Preboot Execution Environment (PXE) images from Windows Deployment Services (WDS) servers or from System Center Configuration Manager (Windows Deployment Services). SCCM).
Cumulative update KB4507469 is causing another known problem, potentially causing a small number of devices "starting on a black screen at first login after installing updates ".
To get around this black screen, users can "press Ctrl + Alt + Del, then select the Power button in the lower right corner of the screen and select To restart, "with the normal restart of the device thereafter.
Microsoft says it is currently working on solutions to these two known issues, which will be made available with an upcoming version of Windows 10.
