Last week Microsoft released Windows 10 Build 10565 to Windows Insiders on both, fast and slow ring. However build 10565 comes with lots new features and improvements.
Now Gabriel Aul, head of Windows Insiders program, tweeted that Windows 10 Build 10575 is in internal fast ring, but it is not clear whether build 10575 will be released to Windows Insiders in Fast Ring.
@callum90ish 10575 is the newest build flighting in the internal Fast ring.
