Biometric Devices Missing from Windows 7 Control Panel

AuthenTec, a company that makes fingerprint scanning devices, worked closely with Microsoft to enable fingerprint authentication without third-party software for Windows 7. Unfortunately, the settings to set up the fingerprint scanner do not always show up in the Windows 7 control panel. To set up the fingerprint scanner you usually can navigate to Control Panel -> Hardware and Sound -> Biometric Devices. From there you can enter your password and register your fingerprints. What if biometric devices is missing from control panel?

To get the biometric devices to show up in Windows 7 control panel download the drivers from AuthenTec’s website (mirror here). I am not sure if this next step is necessary, but the directions I found said to extract the driver with uniextractor. I have extracted the driver for you and zipped it up here (x32, x64) so you don’t have to. Open the zip file and extract the files somewhere and run setup.exe. This installer will create a folder under C:\Program Files\ called WIN7TS and will install the drivers for your finger print scanner. It will also load the necessary components so you can use the fingerprint scanner from the control panel. Once the biometric devices option shows up you can set up everything from the control panel.

If you are getting the ‘Set-up Failure’ error, then try running C:\Program Files\WIN7TS\TrueSuiteApplication.exe directly. It is the same program that runs from the control panel but sometimes has less errors on setup.

MythTV how-to video – Part 2

This is a continuation of Part 1 and in this video I just walk you through a Mythbuntu installation and what options you want to use. The next parts will be about configuring the software past the initial installation.

Sorry for the sound quality. I had to use my digital camera for video (which is what I used in part 1) but for some reason there was a ton of static on the recording.

MythTV how-to video – Part 1

I have been working on my MythTV box for some time now and finally got around to editing the first part of the how to I recorded when setting it up. The first part is just about setting up the hardware (not much new), but the second part (and probably third and forth) is going to be on setting up the software and getting things configured just the way you want them to be.

How-to Modify the Default User Settings in Linux

Just like my other two posts here is how you can modify your default user settings in Linux. This is similar to OSX but instead of “/System/Library/User\ Templates/English.lproj” being our template directory. It is “/etc/skel”.
The skel directory stands for skeleton and it is where the default files and settings come from when you create a new user in Linux. The skel directory is a lot more basic than Windows or OSX mainly because A) not much is needed to create a Linux profile and B) all of the configuration files are stored in plan text and not some fancy .plist or .dat file.
Typically, most distros will only include three files in their “/etc/skel” directory. Those files are “.bash_logout”, “.bash_profile”, and “.bashrc”. If you want to include any more files/settings you can simply edit the configuration in your profile (or a temporary user), copy the setting files to the “/etc/skel” directory, and chown the files with root:root.
What if you don’t want to overwrite the files that came with your distro but you still want to make a skeleton directory? Simple, edit the “/etc/adduser.conf” file and set the SKEL value to whatever you want. Just make sure that the folder is available to root when you are trying to create the new user. In other words, don’t put the folder on a removable drive.
If you are using the GUI to create the new user the files and settings will be copied automatically and if you are using the adduser command just make sure you use the -m flag.
That is really all there is too it. Let me know if you have more tips for creating a user profile or if this helped you out in the comments.

How-to Modify the Default User Settings in OSX

After my post on modifying default user settings in Vista I thought I should follow up with how to accomplish a similar thing in OSX. For OSX there is only one way to accomplish this, and that way is the manual way.

Just like with the manual way in Vista set up two user accounts, your local admin and a template user. Change all the settings you want for the template user and then restart and log in as admin. To copy the files to the default user you will need to open the terminal and follow the commands below.

Local admin isn’t enough, you will need to actually be using the terminal as the root user. If you don’t have root enabled you can find out how to enable it here.

sudo su

The English.lproj is the default user directory for any user that uses the English language. All we are doing here is copying the English.lproj folder and its contents to English.lproj.bak. For these important files ditto is better than cp because ditto will preserve the “resource fork” using the –rsrc option. It is also a good idea to keep a copy of this default user somewhere else besides just this computer in case something happens. I would recommend zipping up the English.lproj folder and storing it on a backup drive somewhere.

cd /System/Library/User\ Template/
ditto –rsrc English.lproj/* English.lproj.bak

Now that we copied a backup we can remove all the files/settings in the old English.lporj directory. If you accidentally delete the English.lproj folder (instead of just its contents) you can create it again with mkdir.

rm -rf English.lproj/*

Here we are just copying everything from our user we set up to the user template folder. Replace “rothgar” in the below command with the username you gave your template user.

cp -R /Users/rothgar/* English.lproj/

This final step will change the owner and group of the files and folders inside the user template to what they should be. All of the default user files should be owned by root and the group wheel.

chown -Rv root:wheel English.lproj

Those are all the steps needed to modify the default user. It would also be a good idea to reboot the computer, log in as admin, and check/repair disk permissions on the drive just to make sure everything is correct before you take an image of the computer. If everything is correct you can test out your settings with a new user and if everything checks out delete your template user.

Let me know if you have any questions, comments, or problems with the process in the comments.

How-to Create a default user in Windows Vista/7

In Windows Vista and Windows 7 there are two ways you can create a modified default user profile. One is automatic and the other is manual. The automatic way is the recommended way according to Microsoft. However, you may run into some problems using this way so I will explain it the manual way too.

First up is the automatic way. For the automatic way you have to use the system preparation (sysprep) tool that Microsoft provides built into Windows Vista and 7. This tool is used for a variety of things but is mainly used for when you need to create a single computer image to put onto multiple machines. To see all the crazy things sysprep can do read the technical documentation on creating an unattend.xml file for sysprep to change everything from your sidebar widgets to your computer name.
Once you have your unattend.xml file created you just need to make sure you have the CopyProfile option turned on in the “specialize” pass and you should be all set.

<CopyProfile>True</CopyProfile>

A few things to note if you are going to do it this way.
1. The account you run the sysprep command from is going to be the account that is copied to the Default profile. So make sure the account you are running sysprep from has admin rights and is set up exactly as you want it.
2. The administrator account is removed during sysprep. Even if you have everything set up the way you want it to be admin will get the same settings as Default user unless you do some fancy scripting.
You can do some more reading on using this method with the following KB article.

Now for the manual method. This method is good if you don’t want to sysprep the computer because all you want to do is change some items for all the users that are going to be logging into a computer. I got all this information from this technet thread but I have used this mothod pretty extensively.
First thing you have to do is to create the profile just as you want it (same as the automatic steps). In this situation though you need to create a second user account because you are going to use the local administrator account to copy all of the settings from the second account to the default profile.
Once everything is set up just the way you want it, restart the computer and log into the local administrator.
After you log in follow the steps below.

1. Right click Computer and select Properties
2. Select Advanced System Properties (elevating as required)
3. In the system properties dialog click the Settings button under User Profiles
4. Select the account you want to use as a template
5. Click Copy To
6. Change the “permitted to use” option to “Everyone”
7. Use the Browse button to select the location of the default profile (C:\Users\Default) You will need hidden files shown to see this.
8. Click OK
9. Click Yes to overwrite the existing default profile

The steps above copy all the files and settings to the profile but there are still things in there that probably reference your old account you had created. To get rid of all those references to the other account you will need to edit the registry hive of the Default user. Follow the steps below to remove all traces of your template account from the default user.

1. Enable “Show hidden files and folders” in Folder Options
2. Disable “Hide Protected Operating System files” in Folder Options
3. Launch Regedit
4. Select HKEY_USERS and go to File -> load hive
5. Navigate to the profile directly of the user you want to load (e.g. C:\users\default for the default user)
6. Open the ntuser.dat file
7. Provide a name for the hive, this will be used as the root key name for that hive under HKU
8. Search the hive for any reference to your old user account.
9. When you find any keys that reference your old user account you can delete the keys (they will be re-created when someone new logs in).
10. Unload the hive before attempting to log in as the user

After you have finished you can log in with a new user to test that all the correct settings transferred to the default profile. If you are satisfied with everything go ahead and go back to System Properties -> Advanced System Properties -> User Profiles and delete the account you set up for the Default User template.

If you have any questions, comments, or problems feel free to leave a comment. I hope this helps.

How-to enable blank passwords in Windows

If you set up a user account in Windows and you want to allow the user account to have a blank password you may find it a little difficult. In order to accomplish this you probably need to change a couple settings in Windows.

The error message you probably got is:

The password does not meet the password policy requirements. Check the minimum password length, password complexity and password history requirements.

To allow a blank password go to Start -> Run and type in gpedit.msc then hit enter.
You should get a window that pops up and has a whole bunch of settings you may have never seen before. On the left side expand Windows Settings -> Security Settings -> Account Policies and then click on Password Policy. On the right side you will need to change a few of the settings.

The three settings you will need to change are Maximum password age, Minimum password length, and Password must meet complexity requirements. Change maximum age and maximum length both to zero and disable the complexity requirements. Once you have these three settings changed you can just close out the window and now you should be able to set a blank password for your user account.
If you cannot change these settings you may be joined to a domain which has these settings locked down. I can’t help you there, but this should help in most other cases.

How-to format a disk to FAT32

When backing up my PS3 for repair I needed to plug in a external hard drive to back up the system. My PS3 is only 40 GB but even that is larger than any USB flash drive I have so I needed to pull out one of my USB hard drives for the backup. I started the the backup process and when it asked for a hard drive I plugged in my terabyte external hard drive but nothing happened. I soon found out that the PS3 will only read FAT32 formatted hard drives. I did not think this would be as much of a problem as it was.
First I tried the format tool built into Windows but I found out that Microsoft decided not to let any drive larger than 32 GB be formatted in FAT32 because…well because they suck and wanted everyone to move to NTFS. So I tried formatting from a command line with: format d: /fs:fat32But I got an error saying the drive is too large for FAT32. I know that isn’t true because FAT32 is technically able to format drives up to 2 terabytes. So I decided to try gparted in Linux. Of course gparted wouldn’t have any problems right? Well in gparted I only had the options for ext2, ext3, reiserfs, and unformatted. That’s a bummer. So how about from the terminal? I tried variations of mkfs and mkfs.vfat but I know there was something I was doing wrong because each time it would just give me a error.
Finally I found a way to do it! There is a program called Fat 32 Formatter. This is a command line program that works in Windows XP/2000/Vista and all you need to do is open a commend prompt and type in:fat32format.exe d: You need to replace d: with whatever your drive is currently mounted as. Once the process completes you have a fully formatted FAT32 drive for your PS3 backup needs. There is a mirror of the fat32format tool here just in case it is removed from online.
And yes this was far more complicated than it needed to be. If you have the commands for completing this task in OSX or Linux please leave them in the comments.

How-to map network drives based on network location

This has been driving me crazy and I cannot figure out how to do it. Here is my problem:
I have a work laptop that I obviously use at work as well as at home. At work I have 6 network drives that are mapped automatically if I log into my computer while at work. At home I have a Windows Home Server with 5 shares that I wrote a batch script to connect to them when I get home. The WHS Connector also adds a shortcut to the shares on my desktop but I want the shares mapped so I can use them as local drives in programs. I also had to write 3 more scripts (1 to disconnect my work drives, 1 to connect my work drives, and 1 to disconnect my home drives) in case I go between work and home without fully turning off my computer and instead just putting it to sleep. I am fairly certain this problem can be fixed with AutoIT or some other tool but I am just surprised this sort of functionality isn’t built into ANY operating system. My laptop has Vista and Linux Mint on it but I know this functionality isn’t in OSX either.
Is there anyone out there that can can suggest something to accomplish this? All I want is something that monitors what network I am connected to, and if that network happens to be home or work, map the appropriate drives. I am going to work on this in AutoIT but I am open to suggestions if you have any.
As soon as I find more information or someone points me to a solution I will update this post with how it works.

Recycling hard drive parts for rocking!

I never saw the appeal of buying all new Rock Band instruments if you already owned the first generation instruments. There was one thing however that made me really like the new Rock Band guitars, and no it wasn’t the new wood finish. This weekend I finally added the one part that I really wanted. A start button guard!
Rock Band guitars aren’t really known for their durability, and one of my guitars refuses to kick into overdrive unless I do a Chuck Norris roundhouse into a back flip in the middle of Visions’ solo before my drummer’s shin bursts into flames and we have to start the 12 song set all over again.
My main problem with adding the guard was figuring out what to use. I thought about using putty, washers, and even cardboard, but then I remembered I had a bag of aluminum hard drive spacers that would work perfectly. All I had to do was get a little super glue and attach it right to the guitar leaving room for the screw that sits next to the start button in case I ever needed to get to the guts of the guitar.
I took a couple pictures just so you could see how the finish product looks. Hopefully this will alleviate those mid-game pauses that sometimes happen when my groin muscles aren’t feeling up to the task of saving my bandmate.
