Announcing Windows 10 Insider Preview Build 15063 for PC and Mobile Insider

But seriously guys, have you seen it happen / has it happened to you?

Short: Browsing OneDrive folder, File Explorer suddenly crashes and at the same time "Set up OneDrive" is shown:



When this happened, trying to sign in using my Windows sign-in Microsoft account fails due "unknown email address".

Nope, works as expected.

Yes. It happened to me. Got all messed up. Even took out Phone Companion app. Had to uninstall OneDrive on my Android phone and reinstall. Took forever for it to sync back up!

And again MS Outlook mail - specially SMTP - is acting up!

Interesting! Could that be related to my OneDrive issues last night?

On another topic, again a strong indicator to make me believe 15063 will be the RTM is that Insider settings in registry are now showing this to be a retail OS. DWORD IsRetailOS = 1, whereas in all previous RS2 builds it has naturally been 0. First noticed it now when checking I'm ready for possible upgrade

Identical, with one exception....

That still doesn't mean no more builds until "full" RTM.

No, of course not. It's just one more indicator, although a strong one. With versions 1511 and 1607 the same happened, builds 10586 (1511) and 14393 (1607) being first to get retail OS status in registry.
