Couple of days back, Microsoft started rolling out Windows 10 Mobile Insider Preview Build 10572 to Windows Insiders on the Fast ring. As you know, build 10549.4 had a bug that prevented upgrade to it from prior builds, so Insiders who wanted to try it out needed to flash back to 8.1. But, it’s been noted by some users that they are seeing an update being offered from their current Windows 10 Mobile build directly to the new 10572 build. This update path was not published and should not be appearing. Windows team have done an investigation and discovered the cause of the issue is related to device provisioning. They are working on a permanent solution, for now they have implemented a short-term fix and seeing a direct update to 10572 should no longer occur.
If your device is in this state and showing a pending update available for download, do the following:
- Reboot your device
- Open the Windows Insider app
- Re-select the WIP ring of your choice (WIP Fast for currently affected users)
- (You may be prompted to reboot again)
This should resolve the issue and prevent the device from re-detecting the update.
