Microsoft rolled out Windows 10 Mobile build 10080 last week, but the company is already working on a new version that could see daylight in the coming days or weeks.

Gabriel Aul, head of the Windows Insider Program, has revealed on Twitter that several new builds are being tested internally by company employees, but no release dates can be provided for the time being, simply because fixing bugs and improving performance could take longer than expected.

Microsoft is always testing new builds internally, but it seems like this time the company is advancing at a much faster pace, especially because we’re getting closer to the moment when the operating system is expected to get the green light for launching on PCs.

This should happen during this summer, most likely in July or August, but the mobile version of Windows 10 won’t arrive until later this year, with some sources claiming that October could be the date when the first Windows Phone devices will be seeing the update.

Fixing bugs

In the meantime, Microsoft is working to fix the bugs it found in build 10080, and this undoubtedly takes time, especially on devices such as Lumia 930, which got hit by a scaling issue.

At the same time, build 10080 came with several migration problems, but Gabe Aul has promised that most of them will be fixed in the coming updates in order to provide smoother installation on all devices.

On the bright side, Microsoft is indeed switching to a faster release pace for Windows 10 builds, especially on PCs, where builds are now launched on average every 16 days. For example, Windows 10 build 10122 was rolled out 21 days after 10074, which got to see daylight 7 days after the previous release, thus keeping insiders’ devices up to date with the latest features developed by the Windows team.

In the next months, however, PC users will get fewer new features and more bugfixes and performance improvements, as we get closer to RTM reportedly scheduled for June.
