A few weeks ago our main complaint about the Windows 10 Mobile Insider program was the slow pace at which updates rolled out.

This is clearly no longer an issue, as new builds of the mobile OS has been coming out thick and strong.

The last public build, 10572, had a bug which prevented users from upgrading from earlier builds of Windows 10 Mobile, and required them to downgrade to Windows Phone 8.1 first.

A new build, 10575, however fixes this issue, and is in testing internally at Microsoft. This is also likely the build that will roll out soon.

How soon was answered by Gabe Aul on twitter, who said:

We do not expect the update to bring much more than the upgrade fix, but be sure to keep an eye on WMPoweruser.com for all the details.
