Surface Pro 12 Inch Keyboard Firmware Update

Ken Ohrn 15

Today I got a notification of a firmware update for this keyboard. The FW version is now 7.4.139.

Can anyone help me find the release notes, or at least some detailed information about what was updated?

Hi Ken Ohrn,

I can understand why you’d want to know what changed with the update. I checked for release notes for firmware version 7.4.139, but unfortunately, I couldn’t find a detailed changelog for this specific version.

Just a quick note that this is a community forum, so moderators and other community members may not have access to internal firmware details that haven’t been published.

You can check Settings > Windows Update > Update history and look under Driver updates for an entry installed on the same date. This may help identify the update package, although it may not explain exactly what changed.

You can also open the Surface app while the keyboard is connected, select the keyboard under connected accessories and expand Firmware Update. This should confirm the installed version and whether it’s up to date.

Since your keyboard is already showing 7.4.139, it sounds like the update installed successfully. If the app shows any additional information or if you notice any issues after the update, feel free to share a screenshot with any personal information removed and I’ll be happy to take a closer look.

Thanks for this.

It looks like a mystery to us all.

Hi Ken Ohrn,

You’re very welcome! I wish there were more details available about exactly what was included in this firmware update.

Since everything appears to have updated successfully, there’s nothing further you need to do if the keyboard is working normally. If you’d still like to look into the changes, you could also contact a live Surface support agent to see if they have any additional information available.

To reach live support:

Go to Contact Microsoft Support and sign in.

Type Live Support and select Get help.

Scroll down and select Contact support.

Choose Surface under Products and services.

Select your Surface model and Confirm.

Choose the available chat or callback option.

I hope they’re able to provide a little more information about what was included in version 7.4.139.

Kind regards.
