Can't log Windows 10 into Windows Server 2012 R2 Essentials domain: Wrong user name or password

No ... you are not going crazy. You just joined a Windows 10 Pro machine (that you in place upgraded from Home likely) to a Windows Server 2012 R2 Essentials domain. Joined just fine. Reboot. Try and login: Wrong username or password. 


If you are like me you try several known-good username / password combos lot's of times until you start to doubt your sanity. 

Silly you! It's Windows 10!!!

Here is the best thread I've found about the issue: 

The fix for me: Run the Windows 10 Media Creation Tool under a local admin account, "upgrade", reboot. Viola. 

Another (unproven to me) registry edit from safe mode ... no good for remote support: See attached PDF.

Being that OneDrive and OneDrive for Business is simply not ready for prime time you might choose to remove it (as much as possible) from your machine and applications. Here is how: 

Remove OneDrive links from Windows File explorer - WARNING: This will sever the connections between Word
  1. Press Win+R and type regedit to open up the Registry Editor
  2. Navigate to the HKEY_CLASSES_ROOT\CLSID\{018D5C66-4533-4307-9B53-224DE2ED1FE6} registry key.
  3. Double-click on System.IsPinnedToNameSpaceTree change its value from 1 to 0.
  4. Log off or restart your computer. When you open File Explorer, the OneDrive entry should be gone from the list.

Remove OneDrive links from Word / Excel - WARNING: This will sever the connections between O365 and the apps. 
  1. Navigate to the following key: HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\SignIn 
  2. NOTE: The version number may vary depending on the version of Office you are running. 
  3. If SignIn does not exist, right-click on Common and select New > Key, and name it SignIn.
  4. Right-click on SignIn afterwards and select New > Dword (32-bit) Value from the context menu.
  5. Name the entry SignInOptions.
  6. Double-click it afterwards and set its value to 3. This turns off the cloud features.
