for some reason when i hav 2 users logged on, and im in the welcome screen of windows xp pro, it asks me for a password that i've never set to login. is there a way to fix this? i've tried setting a password but that doesnt work either. i've tried removing the password but there's no password to remove.

— this usually isn’t a malware/registry problem but an account/policy issue or a confused display name vs. actual user name. Two focused checks will usually find the cause: confirm which local accounts actually exist and whether Fast User Switching / the Welcome screen is behaving as expected.

Quick checks (can be done from a working admin account)

  • List local accounts from an elevated Command Prompt:

    net user
    net user <username>

    Look for “Account active”, “Password required” and “Account locked out” entries so you know which account the welcome tile actually maps to.

  • Verify the Welcome screen / Fast User Switching UI:
    Control Panel → User Accounts → Change the way users log on or off. Toggle “Use the Welcome screen” / “Use Fast User Switching” to see if behavior changes. On XP Pro also check gpedit.msc → Local Computer Policy → Administrative Templates → System → Logon → “Hide entry points for Fast User Switching”.

If you cannot sign in because the password is unknown

  • Reboot, press F8 → Safe Mode, then attempt the built‑in Administrator account (often blank on older XP installs). Once in, change the problem account password:
    net user <username> <newpassword>

    or use Control Panel → User Accounts.

Other useful steps

  • Create a new test user with admin rights and verify Fast User Switching works.
  • Check Event Viewer for failed logon entries to see which username is being rejected.
  • Avoid relying on registry cleaners for this; they rarely fix Windows authentication problems.
    If Safe Mode Administrator is not accessible and account passwords are irretrievable, consider professional data backup first; offline password editors exist but use them with caution as a last resort. ’s suggestion to look beyond simple fixes is on the right track — target the account/policy layer first.

Sounds like there might be a file missing. Have you tried cleaning your registry, running avg, installing sygate, etc?
When you install xp you are asked to set a password. Is this the one that is giving you trouble?

i hav system mechanic 7 and ccleaner for fixing up my registry and i've run those. i still cant hav 2 account on at the same time :(
