I did not update to win 10. Am on Win 7 Ultimate x64.
ok well, there is allot of stuff that comes up when i google 'disable logon windows 7'
They all say similar things by the looks.... here is one example; "How you get there depends on what version of Windows you're using: Windows 7 & Vista: Click Start, type netplwiz , and press ENTER. Windows XP: Click Start>Run, type control userpasswords2 , and press ENTER. Windows 8: Use the Search Charm to search for netplwiz . In the Apps section, click or tap netplwiz."
Hope this helps.
