Rights to Use Other Versions and Lower Editions in Microsoft Licensing

Holding a Microsoft software licence often includes the flexibility to use versions of the software other than the one you initially purchased.

However, while using lower versions is generally permitted, the ability to use lower editions is not a blanket right. Microsoft Product Terms must explicitly permit this for the specific product and edition in question.

What is the difference between versions and editions?

These terms are often confused, so let me clarify.

A version is the specific release of the software, marked by its release number: 2019, 2022, and so on. An edition is the variant that determines the feature set: Standard, Enterprise, Professional.

Version	Release number	2019, 2022
Edition	Feature set	Standard, Enterprise, Professional

What can you do with version and edition downgrades?

Using an earlier version of the software is generally permitted. Using a lower edition requires express permission for the specific product and edition you’re licensed for.

When you do use an earlier version or permitted lower edition, the use rights for the version or edition you’re licensed for remain in effect. You’re operating under the terms of your actual licence, not the terms of the older software.

Downgrading is allowed where expressly permitted. Upgrading to a newer version or higher edition typically requires a new licence, although upgrade rights are included with Software Assurance and subscription licences.

Does downgrading reduce licensing costs?

Using a lower edition doesn’t directly reduce licensing costs, since you’re operating under the terms of the higher edition’s licence. It can, however, influence cost management in other areas: training, support, infrastructure requirements.

How do you stay compliant with version downgrades?

The key compliance point is straightforward: your use of different versions and editions must align with the specific terms and permissions of your licensing agreement. Maintain accurate records of your software deployment, including which versions and editions are actually running where. If an audit arrives, you’ll need to demonstrate that alignment.

Understanding these rights matters in licence negotiations too. Knowing what flexibility you already have can inform decisions and help secure terms that accommodate future needs.
