First things first. This is NOT mine, FULL credit is due to Lea of 7s. 1. First you are going to want to download this.http://www.mediafire...hlaamderdc2lnc1 (Virus Scan https://www.virustotal.com/file/d5f...a9ea6f0f78a3580590d47034/analysis/1345484993/) 2. Extract the folder to your desktop. 3. Open up the folder and click on the pyhton file. Doing so will instal python. 4. Open up the 'gamertags' notepad file and type whatever GamerTag you want to check if it`s availible and save and close. 5. Click on checker and wait a couple of seconds and then click on the notepad document 'working'. Also be aware that some GamerTags may come up because they have the family settings on. Also do NOT capitalize anything in any of the words or it may come up availible. Do not go over thirty words at a time. If you need some help with this I`ll be glad to help.
