I have a Upek Eikon fingerprint reader and I am using it with Windows 7 RTM (for this question, it works the same as in Windows Vista). I was delighted to find that Windows 7 had native support and I could use it with only a driver and nothing more.

Only one thing bothers me: as a geek and nerd, I like my login screens to be tricked out. Whenever I lock my computer, however, instead of showing my user picture and a password login box like everything was normal, it shows a giant fingerprint icon and the text "Scan an enrolled finger to unlock."

Is there any way that I can change something so that it will show my picture and my name so that the fingerprint reader is not so obvious?

Saw your website - sweet work for a 12-year-old! +1 – caliban Oct 3 '09 at 20:03
Something's not right. The website says 12, the SU profile says 19. I smell a lie here :) – alex Oct 3 '09 at 20:10
@Brandon: Thats better than any website I've ever made. Great job! – Lucas McCoy Oct 3 '09 at 20:10
@Alex: Shhhhhh. People can hear you. – Brandon Wang Oct 3 '09 at 20:19
@Caliban: How'd you notice that anyway? Do you regularly click through to people's profiles? – Brandon Wang Oct 3 '09 at 20:19

it took me a while to find out, but I got it! You can change the images in the following .DLL file: c:\windows\system32\BioCredProv.dll

In the bitmap section there are 2 images in 128x128 pixels 24 bit.

Good luck!

What do you recommend using to change the images in the DLL file? – Brandon Wang Jan 18 '10 at 20:20

It's annoying the hell out of me too, but nope, there's no way around it so far I think. Searched since UPEK released their beta Win 7 drivers (oh, about a few months back?) and there's still no answer...

Seriously? Oh, man this sucks. – Brandon Wang Oct 3 '09 at 20:07
Like many other things in techland, I guess. :) Since you are young and talented, I suggest you work your way towards employment in MS or the OS company of your choice... AND MAKE A DIFFERENCE! I'll be waiting right here to reap the rewards of your efforts towards a good UX. – caliban Oct 3 '09 at 20:37

Go to:

C:\Program Files\Protector Suite\rsc

edit the .png, rename as original file. This should fix it up.

It's indeed C:\Program Files\Protector Suite\rsc\ViLogMsg.png – user126515 Apr 4 '12 at 8:39
