.In Windows 10/8, many times you need to use your Microsoft Account instead of a local account, for example, while using the Windows Store. So for this, you have to switch to Microsoft account from the local account. For some, it goes fine while for others, it becomes a matter of trouble. Suppose you upgraded a system from Windows 8 to Windows 8.1 or finally to Windows 10, by using Microsoft account on your system. Now after the upgrade, you may come around following error:
We’re sorry but something went wrong. Your account wasn’t changed to this Microsoft account. Code: 0x80070426
When you get this error, first of all simply reboot.
Another thing you can try here to set up a new user account and switch it to a Microsoft account. But if you’re the one who doesn’t want to set up a new user account and then switch to Microsoft account, you can try the following steps. We suggest you create a System Restore point before proceeding.
Your account wasn’t changed to this Microsoft account
1. Press Windows Key + R combination, type put regedit in Run dialog box and hit Enter to open the Registry Editor.
3. The result will come around these two registry keys:
I have shown one entry in the below image. There would be only one key with this long name for which the email ID you have entered in Find box will match with – so not to be confused at all.
4. After finding both the above-mentioned registry keys, export them at a convenient location, and then Delete. Close the Registry Editor and reboot the machine to get fixed.
Your problem should be resolved.
TIP: This post will help you if you face the opposite problem – Your Microsoft Account wasn’t changed to a Local Account.
