Recently, Twitter user s1z33 shared a few screenshots of Windows 10 for phones Technical Preview build 8.15.12493.42, accompanied with a tweet that reads: "This is Windows 10 Technical Preview for Phones."

The current build is newer than build 8.15.12493.41, which was seeded to one thousand testers for the final round of internal testing to resolve last minutes bugs.

The screenshot for the build 8.15.12493.42 seems to be authentic, as the 'Update Successful' screen carries a quote by Russel Wilson: "Every setback has a major comeback."

Apart from the Update Successful screen, there are two more photos, one showing the Settings panel having several options, and another that shows the new Action Center which contains three rows of customisable buttons, reports Neowin.

Roll back feature and support for 512MB Windows Phone devices

@GabeAul Hi! If we update to W10 (for Phones), will the device still be compatible with the Lumia Software Recovery Tool?!

@talkinglumia @andycoydwilson We'll share more details later, but ability to rollback if you hit an issue is very important to us.

Prior to the availability of the preview build for phone version, Microsoft's Gabriel Aul had confirmed that Windows users will be able to revert to the previous OS version if they experience any bugs. The roll back feature would be of great help as the preview builds usually introduce bugs.

@NicholasHayman I wish I could answer. We're finalizing the list of supported devices for the first preview. Will share soon.

@Qushery @NicholasHayman Hmmm. Do I cave? Don't think you can squeeze anything ELSE out of me:-) Yes, we'll have 512MB devices for 1st prvw.

Aul has also confirmed that the first preview build of Windows 10 for phones will support Windows Phone devices with 512MB RAM. Currently, there is no information about these devices as Microsoft is still finalising the list of supported devices for first preview and will share the details soon.
