I purchased the licenses, joined my companys PCs to the Azure AD on that tenant and ended up with a bunch of inactivated Windows PCs.

If requested, Press “Yes” on the User Account Control pop-up. The M365 Plans page had previously shown that the 'Business' version included a license to both the Office Products and Windows 10 Pro.

Make sure you have an Enterprise Edition product key!.

The May 2022 security update, released on May 10, was the last update available for these versions. The only thing you need is the Enterprise product key! You don’t even need to use an Enterprise ISO or any other install media! The Home and Pro editions of Windows 10, version 20H2 have reached end of servicing. Luckily it’s really easy to upgrade Windows 10. So what’s next? I didn’t want to loose my local data… The question arised: “What is the impact of upgrading to an Enterprise Edition”? As an App-V enthusiast a smile appeared on my face, until… I couldn’t enable the App-V client as apparently I was running Windows 10 Pro Edition (which was available when I joined the Insider Program) and to enable that functionality, I needed the Enterprise Edition… This is due to the new integrated App-V client within Win10 ( ).

But when I updated my laptop to the latent Insider build (14316), I noticed that my local App-V apps weren’t working anymore. So can major changes in Microsofts update policies for business customers.

As an IT Consultant with a Microsoft mindset I really like the Windows 10 Insider program. In the 'Windows as a service' era, updates can arrive when you least expect them.
