KB4034658 cleans Windows 10 V1607 update history

Microsoft released several cumulative updates for Windows 10 (see Windows 10: August 2017 Updates KB4038220, KB4034674, KB4034658, KB4034660). Update KB4034658 seems to wipe the update history under Windows 10 Anniversary Update (V1607) – see also my blog post Windows 10 V1607: KB4034658 clears update history.

Update history is clean

Microsoft has confirmed this bug in KB article KB4034658, where the ‘Known issues’ paragraph says:

#1: For some users, their “Update History” does not list previously installed updates.

Workaround

As an alternative, to see which quality updates have been applied, navigate to the inventory by going to Control Panel -> Programs -> “View Installed Updates”

#2: Some users may find that updates that were previously hidden may not be offered after installing this update.

Workaround

Updates that were previously hidden can be hidden again.

No Office security updates are offered in WSUS

I’ve documented some security updates for Office within my blog post Microsoft Office Security Updates (August 8, 2017). Several German blog readers mentioned, that none of those Updates are not offered via Windows Update. For users having click to run packages of Microsoft Office installed, it is clead. Click to run installs will be updated via the Office installer. But I received also feedback, that WSUS didn’t receive those Office updates.

KB4025336 and KB4034658 blocks access to WSUS

I’ve written about connection issues from Windows clients to WSUS within my blog post July 2017 Updates KB4025336/KB4025331 breaks WSUS. Now I received feedback from users, that KB4025336 breaks again access from Windows 7 SP1 clients to WSUS. Also update KB4034658 for Windows 10 V1607 breaks WSUS, the clients drops error 0x8024401c during update search (I’ve seen several posts about that issue, also here is an article).

KB4034658 breaks WSUS

Also KB4034658 for Windows 10 Version 1607 blocks access to WSUS. During the first update search Windows 10 clients stalls with error 0x8024401C (I’ve seen several posts addressing this issue). Addendum: Here is an article discussing this behavior in detail.

KB4032188 fails in Windows 10 Version 1703

Update KB4032188 for Windows 10 Version 1703 has been released on July 31, 2017 (see Windows 10 V1703: Update KB4032188 (July 31, 2017)). This comment says, that Update KB4032188 for Windows 10 Version 1703 drops an install error. The tip is to repeat the update install several times.

Within this Windows 10 forum thread someone reported issues (slow boot, explorer crashes, VSS issues). The user finally mentioned, that he has used DISM++ to customize Windows 10. Also AVAST antivirus software has been involved.

Update KB4034681 disturbs Network Policy Server (NPS)

Update KB4034681 (August 2017 Security Monthly Quality Rollup for Windows 8.1 and Windows Server 2012 R2) fixes several security issues and the iSCSI bug (see Windows Server: an Update causes iSCSI connection issues). German blog reader Michael H. informed me via e-mail about another issue.

this morning I found another bug associated with KB4034681. We are using NPS with Certificate authorization – which failed this morning. After testing, we found that KB4034681 was the root cause.

Michael pointed to this Technet forum post, where the issues with Network Policy Server (NPS) is also discussed. Microsoft has published a workaround within this KB article:

NPS authentication may break, and wireless clients may fail to connect

On the server, set the following DWORD registry key’s value to = 0: SYSTEM\CurrentControlSet\Services\RasMan\PPP\EAP\13\DisableEndEntityClientCertCheck

Microsofts LDAP Server CVE-2017-8563-Fix

Just a short note: Microsoft has closed a Windows Elevation of Privilege Vulnerability (CVE-2017-8563) for Windows Clients on July 11, 2017 with an update. This update shall improve LDAP authentication. Within this comment a German blog reader reported, that delegated administrators can’t reset passwords anymore.

Update KB4034664 is causing issues with 2nd screen

It seems, that Microsoft’s Update KB4034664 (and KB4034679) for Windows 7 and Windows Server is causing display issues with several applications on a second screen. I’ve discussed details within my blog post Windows Update KB4034664 is causing trouble on 2nd screen.

Other issues

A blog reader reported, that after installing update KB4011051, hyperlinks in Excel works no more. The blog reader posted a link to this Microsoft forum hread, where the issue is confirmed by several users. There is also a comment, that KB4011051 blocks the plugin for Document Management Software LoboDMS in Outlook. Another blog reader send me an e-mail, that some customers are reporting the following issues.

  • Exchange 2010 in SBS 2011 is no more reachable.
  • Docuware data base is is no more reachable.
  • Terminal server 2008R2 has rebootet (although reboot has been switched off)

But I have no further details about the issues listed above.
