Windows 7 Only Cancel Button at Clt+Alt+Del

[GazUK]

Hi,

We have a fleet of X201 Tablet Laptops and We use the HP Officejet 6500 Printer.

As soon as version 14.00 of the driver is installed on these machines upon restart rather than a username to click onto to login at Clt+Alt+Del a cancel button is displayed.

The only work around we have found is to rebuild the laptop and then install an earlier version of the 6500 driver.

What do you think could be causing this and how do we fix it as some users are installing the latest driver themselfs and breaking the laptops.

Have you tried installing the driver in XP compatibility mode? I think this is a driver issue that HP needs to fix.

I tried that it simply says there's issues stopping installation.

I've just updated the fingerprint sensor software = ThinkVantage Fingerprint Software 5.9.3 and its caused the same problem.

In Windows XP, there are gina dll's that control logon. In the past tvtgina.dll replaced the standard gina.dll when installing certain ThinkVantage software. You can search for tvtgina.dll for more info.

I am reading that Windows Vista and Windows 7 no longer use a *gina* file for logon, but instead use a credential provider file. Both the HP printer driver and fingerprint reader software must have replaced your Windows 7 credential provider file or else perhaps installed a gina file that is somehow being read by Windows 7.

I would think you could use Windows System Restore (or if necessary System Restore in SAFE MODE) to revert to before the driver update.

That is correct; Vista and 7 no longer use the msgina.dll for presenting an authentication interface.
AFAIK, 7 and probably Vista use an authui.dll for the interface, which can be reshacked to swap some images, but I don't think can be replaced.

It's also possible that some software installed before the HP drivers and Fingerprint Software contribute to both as a root cause of conflict, which would put the blame on the causative software rather than the apparently causative software.

There's no msgina.dll created and the authui.dll hasn't been modified

Whatever is causing this its fine in safe mode but unistalling the drivers
