How to Enable/Disabled Recording Devices in Windows Vista

I had some strange sounds coming over my speakers and thought it might be one of my recording devices (my built in mic, etc) acting up. To troubleshoot this I brought up the Sound window, clicked on the Recording Tab and right-clicked on each of my recording devices to disable them. It turns out my problem was caused by something else and was easily fixed, but now I have a new issue. How to I enable my recording devices. If you check the Recording Tab in the Sound window, there are no devices listed. Maybe I can enable them directly from the Device Manager. Nope, nothing listed there either...

The solution is fairly simple, but seems to be completely non-standard for windows. Go back to the Recording Tab in the Sound window and right-click in the now blank tab. You should get a context menu that has two options (Show Disabled Devices and Show Disconnected Devices.) Click on Show Disabled Devices and you should now be able to see and enable your devices.

Not a huge issue, but fairly annoying since it is done differently than most other places in Windows (i.e. The network device screen. Disabled devices are still visible but are disabled...)

'Logon failure: unknown user name or bad password.' message in Windows Vista on a Dell D830 with a Fingerprint Scanner and Embassy Security Center. Bl

I received a new laptop for work (a Dell D830) and had a fairly easy time getting it setup for development. To my dismay, I notice periodic Blue Screens of Death (BSOD) while booting into Windows Vista. I looked up the error codes and was unable to find a cause and since my system always seemed to boot normally the next time.

Talking with a co-worker of mine that got a new laptop when I did, we both experienced seemingly random BSODs and were always a bit suspect of the Fingerprint scanner. I didn't really worry about it too much. That is, until this morning.

While booting this morning, I got another BSOD. When my system booted again, I was unable to logon to Windows Vista. Every time I would put in my username and password I would get the following error message.

"Logon failure: unknown user name or bad password."

I also noticed that I wasn't given the option to use my D830's Fingerprint scanner to logon either. I tried logging onto domain accounts and local account with no luck. I rebooted multiple times. I used Vistas startup repair tool with no luck. It was looking like I might have to hit a restore point or restore an image of my laptop.

Luckily for me, my boss had experienced a similar issue. The fix is a mixture of disabling your Fingerprint scanner and Dell's Embassy Security Center. The first step is to boot into Safe Mode by pressing F8 before windows boots and selecting it from the boot menu. You should be able to logon to windows in safe mode (if not, you might have a different issue.) Once you are logged on, perform the following.

Disable the Fingerprint scanner

(this step might be optional, since the second step might do it automatically.)

1. Press your Windows Key and type "Device Manager" and hit Enter to bring up the device manager.
2. Under Biometrics, right click on your fingerprint scanner and select Disable
3. Close the device manager

Turn off Secure Windows Login in Embassy Security Center

1. Press your Windows Key and type "Embassy Security Center" and press Enter (if you don't have this application, you probably have a different issue going on.)
2. Click on Windows Logon
3. Uncheck Enable Secure Windows Logon
4. Click Apply and close Embassy Security Center

After performing these steps, reboot your machine normally and try to login again. Worked great for us on our Dell D830 and was a bit of a pain to track down. I might post an update and let you know if this also clears up my random BSODs.

Hope this helps someone. =)
