# Windows 10 edition downgrade
@ -21,19 +21,10 @@ To perform a downgrade, you can use the same methods as when performing an [edit
Downgrading from any edition of Windows 10 to Windows 7, 8, or 8.1 by entering a different product key is not supported. The only downgrade method available for this path is through the rollback of a previous upgrade. You also cannot downgrade from a later version to an earlier version of the same edition (Ex: Windows 10 Pro 1709 to 1703) unless the rollback process is used. This topic does not discuss version downgrades.
### Firmware-embedded activation keys
As of October 2017, computers that are supplied by an OEM include a firmware embedded product key that can affect the available downgrade paths. If this key exists, you can display it and the pre-installed OS edition by typing the following commands at an elevated Windows PowerShell prompt:
```
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKeyDescription
```

Switching between different editions of Pro might not be possible if the source OS is associated with a [firmware-embedded activation key](#firmware-embedded-activation-keys). An exception is that you can perform an upgrade from Pro to Pro for Workstation on a computer with an embedded Pro key, and then later downgrade this computer back to Pro.

Some slightly more complex scenarios are not represented by the table above. For example, you can perform an upgrade from Pro to Pro for Workstation on a computer with an embedded Pro key using a Pro for Workstation license key, and then later downgrade this computer back to Pro with the firmware-embedded key. The downgrade is allowed but only because the pre-installed OS is Pro.
