Restart Alert Loop caused by Cumulative Update on Windows 10 KB4507453

Microsoft’s release for Windows 10 KB4507453 on July 9 has seen some reports stating that it could cause restart notification loops on some computers.

The issue has caused many users to report it on many support forums across the internet; all of the posts refer to the same problem. The users that encountered this issue were told to reboot their devices once again so they can finish their KB4507453 update installation, even though that has already been done.

Reports show many users have been affected by this issue on Windows 10 Version 1903 and Windows Server Version 1903, but Microsoft has yet to confirm this restart notification loop problem publicly.

Not All Systems With Update KB4507453 Installed Are Affected

German blogger Günter Born that initially reported this reboot loop issue states that not all users with Windows 10 Versio 1903 are experiencing it. He also tried to reproduce this bug but found no leads as to what was the root cause of this problem.

Microsoft’s support website highlights the details that Update KB4507453 features:

• Addresses an issue that may cause BitLocker to go into recovery mode if BitLocker is being provisioned at the same time as updates are being installed.
• Addresses an issue that may cause Mixed Reality users to see a tilted world after connecting their headsets.
• Addresses visual quality issues some users may have seen with Windows Mixed Reality (WMR) headsets and Steam®VR content.
• Security updates to Windows Wireless Networking, Microsoft Scripting Engine, Windows Server, Windows Storage and Filesystems, Windows Kernel, Microsoft HoloLens, Internet Explorer, Windows Input and Composition, Windows Virtualization, Windows App Platform and Frameworks, Microsoft Graphics Component, Microsoft Edge, and Windows Cryptography.

Available Solutions

Born found two possible ways of getting rid of the notification that makes the users restart their PC’s.

The first solution for this problem is to click on “Restart Now” when the notification pops up. Clicking Restart Now on the Start menu will solve nothing.

The second solution is to check on Windows Update for system updates. This will allow the OS to see that there are no new updates available and that no restarts will be necessary.

This second method can be done automatically by the System, but that may take several hours for some of the affected users.

July’s Cumulative Updates Caused More Problems

More cumulative updates like KB453293, KB4503327, and KB4503286 released on June 11 are known to cause issues that have already been confirmed by Redmond. These updates have already affected multiple systems with the Windows 10 Server version installed.

Microsoft acknowledged this issue today and stated that it might block devices from booting if they are using PXE (Preboot Execution Environment) images from SCCM (System Center Configuration Manager) and WDS (Windows Deployment Services).

Another known issue to cause screens going black during the first logon after installing Update KB4507469.

This issue can be dodged with the key combination of Ctrl+Alt+Delete, selecting the Power button and then clicking on Restart, the device working withing parameters afterward.

Microsoft is working on a new Windows 10 release that will fix these known issues.
