First of all:
I'd like to say that this isn't a magical way to get unbanned.
There is some work that needs to be done here and if you're smart enough and fast enough, you can do the whole process after you've learned it in under 30 sec.
No matter what you do here - If you don't have a dynamic IP - you'll still be banned because AIW bans XUID and IP.
This method only changes your XUID and NOT YOUR IP
What will you need:
1. A Brain (VERY IMPORTANT)
2. A user with admin privileges
3. Basic windows knowledge
4. The XUID software supplied @ the end of the post.
5. Hopefully - A network card that supports this method
6. Dynamic IP (**)
Let's get started:
What we are basically doing is using windows options and registry to change manually the MAC Address of your network card, thus crating an new configuration to your computer and generating a whole new XUID code.
(-1). Before we start with our scheme - we need to make sure that the card we are going to change, is
actually the card that's registered as the default one, so that AIW will take it's mac address and not others.
To do that we need to enter the
network connections menu.
For most windows OS it should be under Start -> Settings -> Connection Settings \ Network Connections (I'm not sure)
On windows 7 there is more then one way to get to it but I find the simplest method is writing "network connections" in the search programs and files line and choose "View Network Connections"
When you get to it, on all OS, it should look like this:

After we're there, choose the advanced button -> advanced settings:

You should see all your network connections listed in a row, if the 1st one on the row is something like "hamachi" or "bluetooth connection" you can use the arrows on the right to change the order of those connections.
MAKE SURE ONE OF YOUR INTERNET CONNECTIONS IS THE FIRST ON THE LIST!!!
*It doesn't need to be one that actually works, but it helps.
After we've assured this we're ready to go..
(I'm assuming from now on you can understand what to do so excuse me for no pictures

)
0. Run the XUID tool supplied here in the end of the post and leave it in the background - We will use it again to make sure our method worked.
1. On that same connection that is 1st on the list,
right click and choose Properties
2.0 Before you continue - Look at the name of the network adapter which is used for this connection (should be listed under "Connecting using:") -
REMEMBER IT
2.1 On the same window that opened, there should be a button called
configure - Click on it
3. Go to advanced tab
4. Under Property of your network card, there should be a property called "
Network Address" go to it.
4.1. If there isn't any property listed as "Network Address" in this card (usually on wireless network cards) go back to (-1) and change to another network connection.
5. On that property click on the empty box line - there should now be by default 12 0s on that box.
6. Change that box to any 12 hexadecimal (meaning 0-F) numbers you'd like
Please note: In windows 7, there's a suggestion that the first two numbers should be 12 meaning "12XXXXXXXXXX", though I saw that 00 is working good too.
In the end your state should look something like this:
7. After finishing press OK till we're back to the network connections menu
8. Run the XUID software again, and check if you're XUID has changed.
If not please check any notes left here above or post in this thread.. I will try to help as much as I can.
9. Basically, we're done!
Theses next steps are in-case that while loading the game you are receiving the next error :

Now what you need to do is use the registry editor to delete traces of changed MAC address:
9. Open
Registry Editor (Start -> Run -> regedit)
10. Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class\{4D36E972-E325-11CE-BFC1-08002BE10318} (should be that on all computers)
11. Now this is the tricky part - You need to find the registry of that specified modified network adapter. To find it, go through all the 00** tabs you find there, and look at a Value named
"DriverDesc".
Find the one with the same name as the network adapter from 2.0
12. After you found that 00** which is the same adapter, scroll down the list until you find a value called "
NetworkAddress" (surprisingly enough)
13. Right click on the value -> Delete -> Yes (This will not ruin your connection in any way and is safe to use)
*PLEASE NOTE - IF YOU HAD THIS ERROR, YOU WILL HAVE IT AGAIN EVERY-TIME YOU REACH STEP 7. YOU WILL NEED TO DO THIS PROCESS EVERY-TIME YOU CHANGE YOUR MAC ADDRESS.
(it doesn't take more the 10 secs if after the first couple of times anyway)
14.Now we are officially done. Run the game and enjoy your new fake ID.
Took me a while to write and edit all this stuff
so a simple thank you would be much appreciated
