Hello,

I am experiencing an issue with our school's deployed Win 8.1 machines. At the lock screen, which prompts for a password to re-login, if the user enters an incorrect password, the system disables the enter key and enter arrow, as in no amount of presses will work.

To get around this, the user simply has to select "switch user", then select their username from the list. This takes them back to the login screen, where they can try their password again. However, if they enter their password incorrectly this time, the system does not disable the enter key and enter arrow; it only happens on the initial lock screen.

I have run sfc and chkdsk. Has anyone else experienced this and/or know how to fix it?

We are running Windows 8.1 Pro

Did you create manual image for deployment or is it original Windows image without customization?

If the PCs are part of domain, did you enable any policy to lock login attempt?

You may take a look at event viewer and check whether anything been logged other than login failed, during the time of this issue.

Hi,

According to your description, it seems like Policy problem, Please refer to the path below to check your Policy settings.

Computer Configuration/Windows Settings/Security Settings/Account Policies/Account Lockout Policy

Sorry for the reply delay. I just got back into the office.

It is a manual image for deployment. These are part of a domain, but there is neither a domain policy to lockout after failed logins, nor is there a local policy to do such a thing. (The issue is limited to this specific image; other computers with a different image but in the same OUs do not have this problem.)

And the locking is very situational. It occurs only on the first failed login attempt after waking from sleep/being locked. But even after that failed login, you can hit the switch user button, select the same user, and then try the login again. HOWEVER, now you can fail the login as many times as you want (until the Windows default slowdown of failed logins occurs).

I have checked event viewer several times but do not see anything relevant.

After rebuilding the image several times over and installing each piece of software and driver one by one, I found that the issue was the Omnipass fingerprint software. Uninstalling it resolved the issue.
