This guide will disallow warden to read/write data on your computer and disallow it from sending any information it gathers on your computer (Even though it will not be able to get any). However this will NOT let you run speedhacks or teleporthacks ect. (Because that data is sent from your character and the WoW server will disconnect you).
Securing Your WoW
First, make sure you have your guest account enabled on your computer
-Windows users go to your Control Panel, then to Users and Accounts.
-Click the Guest account and make sure that the Guest account is turned on.
Next, we make a .bat file to load up WoW on your normal computer account but to load it with Guest privileges. Open up notepad or wordpad, type in the following.. (make sure your wow.exe is in this specified position)
Code:
runas.exe /u:guest "C:/Program Files/World of Warcraft/wow.exe"
Save the file as anything... but make sure it is a .bat file. (add .bat to the filename in save)
Run the bat whenever you want to start wow.
IT WILL ASK FOR A PASSWORD JUST HIT ENTER.
And there you go, warden can't stop you. Enjoy.
Edit : If you don't understand how to make the batch file from this guide I have made a premade .bat for you.
