Office has a sign-in button in the top corner of every program by default to give you the (supposed) benefit of linking everything you do to Microsoft’s cloud. There’s a way to disable this “feature” by changing a simple registry key. I understand that this information isn’t new; there are articles out there on how to do this. But without fail I need to look it up every time I reinstall Office, so this is here for my own sanity.
This fix will work for Office 2013 as well as Office 2016, but be aware that it may not work for future versions.
The key is
HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\SignIn\SignInOptions, with a DWORD value of
3. Here’s the .reg file for your convenience, or you can copy/paste the contents below:
Windows Registry Editor Version 5.00 [HKEY_CURRENT_USER\Software\Microsoft\Office\16.0\Common\SignIn] "SignInOptions"=dword:00000003
