Microsoft started rolling out last week's Windows 10 Insider Preview build 15048 to the Slow ring earlier today. The company is now releasing a fresh build to Windows Insiders on the Fast ring. Windows 10 Insider Preview build 15051 is only available for Mobile, as Dona Sarkar said the company doesn't have "enough data" on PC build.

#WindowsInsiders : we don't have enough data on our PC build so we will not be flighting one today.

While we may receive the PC build tomorrow, Mobile Insiders can now start testing out the latest Windows 10 Creators Update Preview build. Again, we are not expecting the company to send out any significant changes anymore, since the upcoming Creators Update is feature locked and currently going through the bug-fixing process.
