Three build releases in a week means thrice the fun! And Microsoft wants you to have fun over the weekend, as it has just released Windows 10 build 15061 for PCs in the Fast ring.
Again, a PC only release, but this has been the norm lately.
As you can tell from the very minor increases in build numbers, this is simply a follow up to the last release, and simply builds on that. There has been nothing notable in terms of new features with these Windows 10 preview versions lately, and this one is no different.
You can take a look at what other improvements and refinements it brings here, though.
However, Dona Sarkar, the Windows Insider Program lead, did mention that the team is tracking down a bug for Windows 10 Mobile. And that we can expect a release on the mobile front soon, as soon as they are able to nail it down.
That said, this is still an important release, particularly for developers and those that are testing out these preview versions of the Creators Update.
Which itself is shaping up fine for a release early next month, April 11 by some counts.
These preview versions meanwhile will continue to be released as Microsoft applies the final polish to what is shaping up to be a highly-anticipated flavor Windows 10.
