Screenshots of what seems to be the RTM build of Windows 10, the Build 10240 have leaked in China. The screenshots lack the Windows Insider preview watermark of, so it seems that we are indeed looking at the RTM build. There is the new Microsoft Edge build and also the version doesn’t have a expiry time confirming its RTM or final release build status.
Gabriel Aul has just confirmed that the new branch from where Insiders (and probably everyone else) will get new builds now is TH1.
