Hello,
I'm gradually migrating my PCs from Windows 10 to Windows 11,
but I'm having a problem with some software that no longer works after the migration.
Is it possible to revert to Windows 10?
Thank you in advance.

Hello,
The only way to revert to Windows 10 would be to redeploy the workstations...
Don't these programs have versions adapted for Windows 11? Do you have any examples of programs that no longer work?
Sincerely,
Ingrid

Good morning ,
Quick question to my main question,
Is it possible that on a laptop, if both Wi-Fi and the RJ45 cable connection are active, there could be an installation conflict?
Here's what the Windows 11 upgrade log tells me:
Code: Select all
Exception: THttpClientSocket.OpenBind(..............): Is a server available on this address:port? [remoteip=] [#3 Not Found]

There are two places where I removed the path to our network for security reasons. (...........)

Hello Catherine,
The issue can indeed occur during an upgrade. For this type of update, it is recommended to use an Ethernet (RJ45) connection to ensure stable communication between your computer and your WAPT server throughout the operation.
The EBP 2022 version appears to be compatible with Windows 11:

Hi Catherine,
regarding the initial downgrade issue, you could try using the tis-windows10-upgrade-template package [1] by modifying the check condition for the default in the def install() function. This should force a Windows 10 reinstallation.
If the machines were migrated less than 10 days ago, it's possible the old version hasn't been cleaned up yet, and you could revert to the previous version using the "roll back" option in the system recovery options. I don't know the corresponding command line to automate this with a package.
If you're stuck on Windows 10 on these machines, you could look into upgrading to Windows 10 LTSC 2019; it's supported until 2029 (that's what I have on my machine).
Regarding the second issue about the Wi-Fi problem, you should start a new thread to avoid mixing topics.
Kind regards,
Denis
