It's Patch Tuesday again, so Microsoft is back with another round of Surface firmware updates. This month, we're getting firmware updates for Surface 2 and Surface Pro 2, but not the original Surface RT or Surface Pro. And, oddly, not for Surface Pro 3, though Microsoft had previously promised to deliver such an update before the device's June 20 street date. I assume that's still the plan.
Here's what's new this month.
Surface 2/Surface 2 4G LTE
The following updates in "System Firmware Update – 6/10/2014" apply to Surface 2.
Surface 2 UEFI (v4.21.500.0) update enhances overall system stability, including boot and reboot scenarios, compatibility with Surface Power Cover, and increased battery life when Surface 2 is not in use.
