How to hide or remove email address from Windows 8 lockscreen?
Solution 1:
I know only a way to hide all info:
Type regedit in Start Screen then open Registry Editor
Go to
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\SystemSet
dontdisplaylastusernameto 1Right click then create a DWORD
DontDisplayLockedUserIDwith value of 3
Then all info here will hidden, and will need fill both username and password to login. Username can use email, or simply all lower cases first name (username is case insensitive).
