Hi, thanks for the answer. I thought it was about the same issue.
Now I did some investment in some of these laptops having the problem with SEBDummy.
I've noticed after some searching that there was an underlying service installed on these devices, that acted as an antivirus. Probably it was installed with some other software. So the problem of my school has been fixed. Thank you to say in these posts to look for an antivirus or something similar. So Defender for Endpoint is working good with SEB.

The school has 2 types of computers, SEB 3.6.0 worked on Lenovo computers (picture 1) and did not work on HP computers (picture 2).

Thanks for your report. This is indeed a known issue for which we currently don't have a solution:

Our current suspicion is an interference of either Windows (Defender) or then a third-party application like anti-virus software or alike. But we'd need a reliable way to reproduce the issue, otherwise there's nothing we can do at the moment, various attempts at determining the underlying cause have thus far failed.

I see that you have Bitdefender installed; you might want to try and disable it on the systems with the problem to verify whether it may be interfering with SEB. Or you could uninstall all software which is on the HP systems, but not on the Lenovo systems in an attempt to pin down a possible interference with SEB.

This issue is stale because it has been open for 28 days with no activity. It will soon be closed automatically if there are no updates.

I hope someone will read this, because I mentioned this issue probably as first in #765
Even SEB 3.7 has the same error as I've described in previous link: SEBDummy can't be changed. I suppose the start of the problem has to do with some actions that couldn't be done even if I'm the administrator of the device, because it's also managed by Intune.
Because I read Antivirus. We're using Defender for Endpoint, the cloud solution by Microsoft. It isn't possible to turn it off...
Some devices have this problem, while many others doesn't. But SEB has to work on all devices. Hopefully SEB could fix this. Thanks!

@frederik-it This issue relates to another problem, namely the inter-process communication of SEB's application components and does not relate to the ease of access configuration issue.
With respect to the issue mentioned in #765, I can only reiterate the information already provided in comments #765 (comment) and #765 (comment): If you're not using the SEB Service application component, then SEB will not manipulate the ease of access registry value (but will validate it, which is likely the cause of your issue). Thus please try to bypass the service component in your configuration(s) and clean up any potentially remaining ease of access registry values (either manually via Registry Editor or then e.g. using the SEB Reset Utility).

@frederik-it Excellent, that is good to know and thank you for providing the information, it may help other users.
