Note:

- When Surface updates are provided via the Windows Update service, they are delivered in stages to Surface customers. As a result, not every Surface will receive the update at the same time, but the update will be delivered to all devices. If you have not received the update then please manually check Windows Update later.
- If you update the operating system on your Surface, this will clear your existing update history.
- Firmware updates cannot be uninstalled or reverted to an earlier version 

About e-Reader Firmware:

Update your e-Reader firmware version to this release, and the device can get touch features improvements, application updates, usability and compatibility enhancements, as well as several other related changes.

If you want to apply this version, the installation process isn't much of a hassle because each manufacturer tries to make it as easy as possible: most of the times, you need to transfer the new firmware to the e-Reader through the available methods, and initiate the upgrade from the setup menu.

Still, since there are several ways for entering update mode, and numerous e-Reader models and manufacturers, it would be best if you read the installation steps and follow them precisely.

Bear in mind that if you try to apply an incompatible firmware, or fail to completely perform the upgrade, the unit can encounter serious malfunctions and might even be rendered unusable.

Therefore, if this package is developed for your device, click the download button, get the package and apply the new firmware. Also, don't forget to constantly check our website so that you don't miss any new releases.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
