People who have been testing the latest beta versions of Microsoft’s Windows 10 for smartphones have a new operating system build to play with Thursday. The company began rolling out build 10581 of Windows 10 Mobile to members of the Windows Insider Program’s fast ring who are trying out the cutting-edge updates Microsoft has been making available to the public.
This build doesn’t have anything in the way of new features over its immediate predecessor, but Microsoft general manager Gabe Aul listed a whole bunch of performance improvements and bug fixes coming to the operating system. The biggest fix is that this build finally allows people who were running build 10536 of Windows 10 Mobile (which was released last month) to update directly to the new version without requiring them to first erase their phone and re-install Windows Phone 8.1.
Microsoft released two builds earlier this month that couldn’t be directly upgraded from 10536, which meant users had to go through a massive rigamarole in order to get onto the latest OS if they wanted it.
