Last night, Microsoft released Windows 10 Mobile build 15063.2 to Insiders in the Fast Ring. The latest build of Windows 10 Mobile only includes a single bug fix, so it honestly isn’t anything exciting. Today, Microsoft is rolling out the same build to Insiders in the Slow Ring which isn’t surprising to see as we are pretty close to the release of the Creators Update at the moment.

In case you are wondering about the bug fix: Microsoft has fixed an issue which prevented users from upgrading to the Creators Update from if they are running the Anniversary Update on their device.
