It's possible to hide user accounts from the Welcome Screen (even though they still exist and work fine). You do this using a registry key under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts\UserList. If this key exists, you'll probably find two dword entries with the same name as your account (and a value of 0, which means to hide the account). Delete the entries if they exist and reboot your computer and your accounts will be back. + 0 Votes Reponse To Answer krishnagopi614 1 year ago no.. sir,I can't login to my finger print also...I tried these register also + 0 Votes Reponse To Answer gechurch 1 year ago I don't know the answer then. Have you tried Safe Mode yet? If it works from there you can at least start diagnosing, or create a new account to test further with.Failing that, if it were me I'd probably try a bootable CD next. Run a utility to show you the list of user accounts on the machine (something like @ctive Password Changer). This would at least let you confirm which accounts still exist. Another option is to download the trial of Microsoft DaRT CD for Windows 7. Boot off that and run a System Restore to a date before the problem started.
