Preview for Developers or Windows Insider

[k72]

Possibly a dumb question, but what is the difference between Preview for Developers and Windows Insider? I couldn't get Windows Insider to work on one phone until I enabled Preview for Developers. On my other phone, Windows Insider just reboots my phone.

Preview for Developers is basically the predecessor of the Windows Insider program with some differences.

It was originally a way to push final builds of software without firmware and carrier intervention, the Windows Insider builds are typically more unfinished but otherwise similar in idea. Early access for people who want it.

But as far as results are concerned, the Preview for Dev program is for updating a phone to Windows Phone 8.1 Update 1, which some phones dont have and Windows Insider is for updating to 10.
