If you’re a member of the Windows 10 Insider Program, you can download ISOs for the latest release of Windows 10. The official version is Windows 10 Creators Update’s RTM build 15063 and is officially released now, after an accidental release recently.
The remainder of the Windows 10 world will need to wait till April 11 for the wider release. Given that lag, it’s possible the broad public release could be a different release if any issues are detected.
The ISOs that are available are for the Home, Pro, Enterprise, Education, Home Single Language and Home China versions for 32-bit PCs and 64-bit PCs.
If you’re a member of the Insider Program, you can find the ISOs here.
