KB4345418 and KB4054566 causing high CPU load

The updates KB4345418 and KB4054566 which Microsoft released on July 16, 2018 seem to cause issues such as high CPU load or RDS connection issues on Windows Server 2012 R2 and Windows Server 2016 in some scenarios.
Microsoft released several updates on July 16, 2018 designed to resolve issues that were introduced by updates released on the July 2018 Patch Tuesday.
The updates fixed issues such as connectivity loss scenarios, stop error 0xD1 when running network monitoring workloads, issues that caused the restart of SQL servers to fail, or issues when trying to stop the World Wide Web Publishing Service.
The updates, KB4345418 for Windows 10 version 1607 and Windows Server 2016, and KB4054566, the Microsoft .NET Framework 4.7.2 for Windows 8.1, Windows RT 8.1, and Windows Server 2012 R2, were designed to address the issues described. It appears that the updates may introduce issues of their own on systems they are installed on.
Server administrators started to report issues that they identified after installation of the updates shortly after release.
One issue was that Microsoft Azure Active Directory Connect (AADConnect) stopped working after installation of the updates on Server 2016 and 2012 R2 machines.
A user on the Ask Woody forum described the issue in the following way:
Even with the updated patch on Server 2016 (KB4345418) is still causing an issue with AADConnect servers that triggers a 100% CPU spike on some of the Health and Reporting monitoring services, only fix at this point is to uninstall the latest update. It seems to impact at least 2012 and 2016 servers. …
A forum thread on the Microsoft Developer Network forum confirms the issue. One user reported that uninstallation of KB4054566 resolved the issue in a Windows Server 2012 R2 environment.
Restarting the services brings CPU usage back to normal, and the only option right now to resolve it appears to be to uninstall the latest updates.
But issues with AADConnect were not the only ones that administrators reported after release of the patches.
Matt Wilkinson reported on Twitter that KB4345418 was causing black screen upon login issues when using Remote Desktop Services on Server 2016.
KB 4345418 is causing issues on Server 2016 RDS with a black screen upon login. Have mitigated this issue with a script to delete firewall rules that are created per user. Black screen returned with this update.
Closing Words
The July 2018 updates caused a lot of issues for users up until now. It is not the first time that updates that Microsoft releases cause issues on systems they are installed on.
I think it is fair to say that users need to understand that any patch that Microsoft releases can have unforeseen consequences; some will even wreak the system. The creation of backups is advised.
Now You: Did you run into issues after installing patches recently? (via Born)


What mental age of reader are you targeting with the first sentence? 10?
Why not write an article on how to *avoid* upgrading from W10 to W11. Analogous to those like me who avoided upgrading from 7 to 10 for as long as possible.
If your paymaster Microsoft permits it, of course.
5. Rufus
6. Ventoy
PS. I hate reading these “SEO optimized” articles.
I used Rufus to create an installer for a 6th gen intel i5 that had MBR. It upgraded using Setup. No issues except for Win 11 always prompting me to replace my local account. Still using Win 10 Pro on all my other PCs to avoid the bullying.
bit pointless to upgrade for the sake of upgrading as you never know when you’ll get locked out because ms might suddenly not provide updates to unsupported systems.
ps…. time travelling?

This happens when you schedule a post in WordPress and update it before setting the publication date.
Anyone willing to downgrade to this awful OS must like inflicting themselves with harm.
I have become convinced now that anybody who has no qualms with using Windows 11/10 must fit into one of the following brackets:
1) Too young to remember a time before W10 and W11 (doesn’t know better)
2) Wants to play the latest games on their PC above anything else (or deeply needs some software which already dropped W7 support)
3) Doesn’t know too much about how computers work, worried that they’d be absolutely lost and in trouble without the “”latest security””
4) Microsoft apologist that tries to justify that the latest “features” and “changes” are actually a good thing, that improve Windows
5) Uses their computer to do a bare minimum of like 3 different things, browse web, check emails, etc, so really doesn’t fuss
Obviously that doesn’t cover everyone, there’s also the category that:
6) Actually liked W7 more than 10, and held out as long as possible before switching, begrudgingly uses 10 now
Have I missed any group off this list?
You have missed in this group just about any professional user that uses business software like CAD programs or ERP Programs which are 99% of all professional users from this list.
Linux doesn’t help anyone who is not a linux kid and apple is just a fancy facebook machine.
Microsoft has removed KB5029351 update
only from windows update though
KB5029351 is still available from the ms update catalog site
1. This update is labaled as PREVIEW if it causes issues to unintelligent people, then they shouldn’t have allowed Preview updates ot install.
2. I have installed it in a 11 years old computer, and no problems at all.
3. Making a big drama over a bluescreen for an updated labeled as preview is ridiculous.
This is probably another BS internet drama where people ran programs and scripts that modified the registry until they broke Windows, just for removing stuff that they weren’t even using just for the sake of it.
Maybe people should stop playing geeks and actually either use Windows 10 or Windows 11, but don’t try to modify things just for the sake of it.
Sometimes removing or stopping things (like defender is a perfect example) only need intelligence, not scripts or 3rd party programs that might mess with windows.
Windows 11 was a pointless release, it was just created because some of the Windows team wanted to boost sales with some sort of new and improved Windows 10. Instead, Microsoft cannot support one version well let alone two.
Windows 11 is the worst ugly shame by Microsoft ever. They should release with every new W11 version a complete free version of Starallback inside just to make this sh** OS functionally again.
motherboard maker MSI has recently released a statement regarding the “unsupported processor” blue screen error for their boards using Intel 600/700 series chipsets & to avoid the KB5029351 Win11 update:

While there may be changes or updates to the Windows 10 Store for Business and Education in the future, it is premature to conclude that it will be discontinued based solely on rumors.
My advice, I left win 15 years ago. Now I’m a happy linux user (linuxmint) but there is Centos, Fedora, Ubuntu depending on your needs.
