We are trying to find out the final answer, does M365 Business Premium contain Windows Pro/Business license or not. From M365 Admin Portal, I see that Windows Business app is available for users assigned with premium license, but this article says that only the upgrade from existing Pro is supported: https://learn.microsoft.com/en-us/microsoft-365/business-premium/m365bp-upgrade-windows-pro?view=o365-worldwide&source=recommendations#purchase-windows-10-or-11-pro-to-upgrade-from-windows-10-or-11-home
In our case, customer is buying low level consumer laptops with Windows Home version and reinstall them with USB installation media to Pro/Business. Is that supported without buying Professional license additionally?
Here below is the screenshot from User's apps in M365 admin center.
After carefully reviewing the service description of Microsoft 365 Business Premium, I found that it offers an upgrade service,
but it does not provide Windows 10 Pro without a previous Windows license.
If you require a Microsoft 365 subscription that includes a license for Windows 10,
I would suggest trying out Microsoft 365 E3.
I hope this information proves helpful.
Let me know if you have any further queries.
Thankyou
Sujan Roy.

Currently Ms365 Business premium includes a W10/11 Bussiness License

What do you mean by previous license? Home is a previous license here.... just want to make sure, can home be upgraded to pro / business without puchasing additional Windows license. (only using M365 Business premium).

From our experience, if I deploy a windows 10/11 pro without any product key (tested in MANY labs), using a Business Premium and joining the device to Entra ID/Intune. Windows WILL activate on Windows Business license included in business premium.
The documentation may say otherwise, but in practice it is as I described. You can test and see for yourself....
