There are no June firmware updates for the Surface RT, Surface Pro, Surface Pro 2 or Surface 2 tablets.
As Microsoft notes on its Surface History Web sites, Surface updates are provided via Windows Update, meaning they are delivered in stages to 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," the site says.
Microsoft officials still have not disclosed when the company will make available an update for the ARM-based Surface RT and Surface 2 that will provide some unspecified subset of Windows 10 features for those devices, since they will not be able to be updated to full Windows 10.
Microsoft also updated its Microsoft Band firmware on June 23. According to the Band Update History site, the June update includes "general fixes and improvements." I asked Microsoft for more details and a company spokesperson said "we have nothing to share."
There's also no word so far on when Microsoft will roll out an updated version of its Band device. The only thing I've heard on that front is the Band 2.0 will likely continue to run firmware, and not a Windows 10-based operating system core.
