Note:

- Surface updates are released in stages—not every Surface will receive updates at the same time, but they'll be delivered to all devices. 
- After the updates have finished installing, it's recommended that you install all available optional updates. To install optional updates, from Search, type View Optional updates and select it under Best match. If updates are available in Driver updates, click through to download to ensure that all Surface drivers listed in the release have been installed.
- Firmware updates can’t be uninstalled or reverted to an earlier version.
- When you install the latest update, you'll also get all the previous updates if your Surface doesn't have them already. Only updates that apply to Surface will be downloaded and installed.
- After the updates are installed, restart your device to complete the installation process. To restart your device, select the Start button, and then select Power > Restart.
- If multiple downloads are available and you want to update your Surface with the latest drivers and firmware from the Download Center, select the .msi file name that matches your Surface model and version of Windows.

About Tablet Firmware:

By applying this firmware, your tablet can benefit from improved system stability, network-related functions and performance, enhanced touch experience, various fixes for problems encountered throughout the device's usage time, as well as several other changes.

The installation process isn't much of a hassle because each manufacturer tries to make it as easy as possible: usually, you must transfer the new firmware to the tablet, and initiate the upgrade from the setup menu.

However, due to the large number of tablets and manufacturers, as well as various ways for entering update mode, we recommend that you read the installation guide, and perform the upgrade only once you have familiarized yourself with the steps.

Bear in mind that, before you get this release, you must check to see if the available firmware is developed for your tablet model and SKU (stock keeping unit) – if you apply an incompatible software, the device will encounter serious malfunctions and can even be rendered unusable.

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