To downgrade eligible Windows software, end users must:
- Purchase a PC preinstalled with Windows software.
- Accept the Microsoft Software License Terms.
- Perform the downgrade process to the eligible downgrade product
using the media/key from a genuine, previously licensed OEM or retail
product.
Follow these steps to downgrade to an earlier version of Windows software:
- Use genuine Windows media and a corresponding product key for
the version of Windows that is eligible for downgrade. The media/key
should come from a previously licensed product from the OEM or retail
channel.
- End users who are licensed separately through Microsoft Volume
Licensing (VL) may provide their VL media and key to a system builder to
facilitate the downgrade on their own systems.
- Insert the downgrade-eligible version of Windows media and follow the installation instructions.
- Enter the product key.
- If the software was previously activated, it cannot be activated
online. In this case, the appropriate local Activation Support phone
number will be displayed. Call the number and explain the circumstances.
When it is determined that the end user has an eligible Windows
license, the customer service representative will provide a single-use
activation code to activate the software. Please note that Microsoft
does not provide a full product key in this scenario.
- Activate the software.
For scenarios involving large volume downgrades, end users are
encouraged to consider VL which provides the benefits of reimaging
rights and volume activation, which can make the process of downgrading
much easier.
Because downgrade rights apply to end users, they are not designed
for third-party facilitation, which has many complications. Also, such
facilitation is not suitable for carrying out on a large scale.
