I finally found a good guide to create a Windows 7 Bootable USB Drive. It is definitely the best on the internet, and has instructions for creating within XP, Vista, and Windows 7.

Question: How can I retrieve my Windows key when I can not access my computer? (How can I retrieve my Windows key offline) (How can I retrieve my Windows key with a Linux Disk)

Answer:
First, there is no good way to do this using a Ubuntu or Linux Live disc. Sorry.
But, there is an easy way to do this.

Note: Most computers have the key on them somewhere in the form of a sticker. Make sure that the sticker Windows version matches the version installed on the computer to avoid upgrade confusion. If this sticker is missing, proceed using the key.

You can use Hirens Boot CD to retrieve your Windows Keys offline. Hirens Boot CD has MiniXP on it, which is how we will address retrieving your key.

You can download Hirens Boot CD here. For more information of what software is on the CD, click here. For instructions on how to make a bootable USB for Hirens Boot CD, click here (medium difficulty) .

Instructions:

(Ease: Medium. 3/10 difficulty.
Download and burn the newest version of Hirens Boot CD (in our case, it was version 14.0). Download link is above.

Upon booting of the CD, select the option to boot into “Mini Windows Xp”. This will take a moment to load, especially from the CD.

From the MiniXP Desktop, double-click the “HBCD Menu” shortcut.

Select, from the menubar, Programs > Passwords / Keys > Product Keys >
Select XP Key Reader for reading XP Keys, or ProduKey for others.

For XP  Key Reader:
On the XP Key Reader window, click “Browse” and select the drive with your Windows installation, and select the Windows folder.
Then, on the main program window, click “Read Remote Key”

For ProduKey:
When you open ProduKey, a Window will appear. Choose “Load the product keys from the external Windows directory” and click “Browse”.
Select the drive with your Windows installation, and select the Windows folder.
Click OK at the bottom of the source window. (Tip: If your screen is small, you may not be able to see the OK button. Simply press ENTER.)

Wait a moment, and the keys will load.

Tip: Write your keys down twice. If you write the key down wrong by accident and reformat, you may be out of luck for getting the key back again.

“Windows could not log you in. The trust relationship between this computer and the primary domain failed.”

If you have ever seen this error, and said to yourself:”*@*$&@@ !! How the !*$&@^@ did this happen?” then I am totally with you.

What this means:
Really, I have no idea. Nor why it happens, or why XP never had this issue but Vista and 7 do. Essentially, it’s a security thing when either the client or the server has reasons not to trust the other.

How to fix it:

1. Unplug the computer from the network, and log in using cached credentials.
2. Drop the computer from the domain by changing the domain name to a workgroup.
3. Reboot the computer.
4. Log in using the built-in administrator account (you should make sure you know this before dropping it from the domain! Otherwise, you will need to create this user by alternative means).
5. Join the computer back to the domain,
6. Reboot.

If this fails, you can try another method located here:

“Account Already Exists” error on Windows 2000, XP, and Windows 7/Vista indicates that Active Directory already has the computer listed. You can not have two computers of the same name, even if one is offline. (If the other is online, you will see: “Duplicate Name on Network”. More about this further down)

How you fix it:
Log in to your Active Directory computer, and go to “Active Directory Users and Computers”. Find the computer name you wish to use and delete it.
Return to the computer, and set the computer name as you normally would. (Sometimes, Active Directory changes can take a short period of time before actually taking place. Also, if you have multiple Active Directory computers, you may run across the issue of having to wait for them to synchronize the change).

How to avoid it:
Before changing the name of any computer, you should drop the computer from the domain. The best way to do this is to switch the computer from being on the domain to being on a workgroup. The computer says: “I’m leaving” to the Active Directory server, and Active Directory drops the computer from it’s database.

Duplicate Name on Network:
You must find the other computer name and change it before you can use the name without receiving this error. You should still be able to log in and use the computer with this error, but it is very bad network practice to do so.
