# Windows 10 edition downgrade
**Applies to**
- Windows 10
This topic provides a summary of supported Windows 10 edition in-place downgrade paths. A valid product key for the destination edition is required. You might need to downgrade the edition of Windows 10, for example, if an Enterprise license is expired.
To perform a downgrade, you can use the same methods as when performing an [edition upgrade](windows-10-edition-upgrades.md). If a downgrade is supported, then your apps and settings can be migrated from the current edition to the downgraded edition. If a path is not supported, then a clean install is required.
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.
**Note**: As of October 2017 computers that are supplied by an OEM include a firmware embedded product key. If a computer has this key, it will affect the available edition downgrade paths. To determine if a computer has a firmware-embedded activation key and to discover the the original, pre-installed OS edition, type the following at an elevated Windows PowerShell prompt:
```
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey
```
Scenario example:
- Downgrade Enterprise
- Original edition with firmware-embedded key: **Pro**
- Upgrade edition: **Enterprise**
- Valid downgrade paths: **Pro, Pro for Workstations, Pro Education, Education**
>**Windows 10 LTSC/LTSB**: Due to [naming changes](https://docs.microsoft.com/en-us/windows/deployment/update/waas-overview#naming-changes), product versions that display Windows 10 LTSB will be replaced with Windows 10 LTSC in subsequent feature updates.
