Windows 10 V1909 and a possible GPO Issue

[German]Windows 10 November 2019 Update (Version 1909), seems to have issues with Group Policy because changes cannot be set reliably. At least a blog reader has made this experience in a test environment.


Blog reader Markus K. runs some test systems with the Windows 10 November 2019 Update (Version 1909) at a university in Austria and wanted to deal with the topic of Group Policy deployment for Windows clients. He noticed a problem. Markus wrote me before Christmas:

We have been trying to roll out in our test environment for quite some time in 1909.
Since we have a lot of GPOs, it is essential that they work in a reliable way.
Now comes the fun part, sometimes it works and sometimes it doesn't :).

Markus states that the Windows 10 version 1809 machines never have issues with the distribution of the GPOs. On the computers with Windows 10 version 1909 it is just coincidence if a group policy is working or not.

Markus wrote me that neither the event logs nor the GPSVC log are very useful. In the GPSVC log, Markus sees that the CSE registry is creating a kind of error (permission denied?). And it comes even harder, as Markus found out:

It's funny that if you manually start "gpudate /force" some time later, the application of group policies works after the next reboot.

The problem also does not affect all Windows 10 version 1909 clients. Markus writes the following:

Other [Windows 10] V1909 [clients] will be installed and are usable after a marginal delay.

Markus says about this: It looks like a random bug to me, which makes the diagnosis especially pleasant. They have about 700 GPO objects in the test environment alone, which doesn't make debugging any easier. At this point he asks if something is known, or someone who has heard about it. Then he and probably the rest of the blog readers would be grateful for any tip. Thanks for the tip.

    we got the same behavior after first tests in 1909. After a Support Case @ Microsoft.
    we set the following GPO-Key and the problems are gone.

  2. Max Bado says:

    Which of the two options did you set within this Group Policy? The two options are:
    "Do not apply during periodic background processing"
    "Process even if the Group Policy objects have not changed"

      It seems that the root cause is different. Markus K. did send me additional details. Will post a follow up article.
