I can't access my user account even though password is correct.

I have not been able to access my user account even though the password is correct. It happened both to our 2 admin accounts so now we are only using the guest user account.


Something must have corrupted those accounts.

You can try to fix with Safe Mode - repeatedly tap F8 as you bootup. The ADMIN account in Safe
Mode has no password by default (so unless someone changed the password it should be available).

These similar problems and fixes may help :

Some programs like the Google Updater (if you added the Google Toolbar, Chrome or Google Earth)
has been known to cause this issue.

Try these to clear corruption in case it has a role.

1. Run DiskCleanup - Start - All Programs - Accessories - System Tools - Disk Cleanup

2. Start - type in Search box -  COMMAND   find at top of list -  RIGHT CLICK  -  RUN AS ADMIN

sfc /scannow

generates in Windows Vista cbs.log

3. Then run checkdisk - schedule it to run at next start and then Apply OK your way out then restart.

Other methods :

Use the Hidden Admin Account to lower your account to user (to lowest level) APPLY/OK  then go back
and reset it to Admin APPLY/OK - this helps clear corruption. Do this a few times. Do the same for other
accounts that might have problems. Then if needed you can also reset your passwords in the accounts.
Remember to leave your account as Admin and the others at the level you wish.

Make another Admin Account with your password and use it to fix the others when needed. (just to
repair with, not to use as regular account, a safety valve) Always keep a spare ADMIN account.

DO NOT LEAVE THE HAA ENABLED OR USE IT DAILY. If it corrupts you are toast!

How to Enable or Disable the Real Built-in Administrator Account in Vista

You can run the Hidden Admin Account command from the Command Prompt from here if needed.

This tells you how to access the System Recovery Options and/or from a Vista DVD

If you can't access your old account you can still use an Admin to migrate to a new one (remember to always
leave an Admin Account that is unused except to test and fix).
