I believe this might work but obviously do a registry back up first but if you cant get into windows at all I don't know a way of doing it, If you're not happy about using 'regedit, then don't try it.
I found this tweak on the Internet to alter the Registry so a password is not required to get into the Recovery Console. I have proven this tweak works as intended by switching between the default registry DWORD setting ('0') and the tweaked DWORD setting ('1'). When the DWORD value is set to '1' I can access all functions of the Recovery Console but when set to the default value of '0' no password allows access to the Recovery Console. The tweak I used is as follows:
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\setup\recoveryconsole]
"securitylevel"=dword:00000001
"setcommand"=dword:00000000
---
The DEFAULT value for "securitylevel"=dword:00000001 is '00000000' (zero).
