Instructions
Download and install the "Cheat Engine" software (see Resources).
Start up "World of Warcraft" game client first and log into your game account. Once the game is loaded and operational, start "Cheat Engine."
Locate the small computer icon in the upper left corner of the Cheat Engine program screen. The icon is directly under the "File" dropdown menu. Click on the computer icon to open the list of processes running on the computer. Since "World of Warcraft" is running, the program will detect it and will display 00000294-WoW.exe in the list. Click on 00000294-WoW.exe to highlight it, then click the "Open" button below the selection list.
Place a check mark in the box next to the label "Enable Speed Hack," then enter the desired speed increase in the box directly under that label. A setting of between 15 and 20 is optimal. Click the "Apply" button when ready to begin playing.
Minimize the "Cheat Engine" screen (don't close it) and maximize the "World of Warcraft" game screen and play. You will notice that your character moves through the game fast. If you find that the character moves too fast to control, reduce the speed setting in Cheat Engine and click "Apply" again to let the change take effect.
Turn off the speed increase when desired by removing the check mark in "Enable Speed Hack," then click "Apply" to disable it completely. Return to the game and play at normal speed.
