Step One: Create a directory to hold the steamCMD file and Left 4 dead 2 Server files

Create C:\steamcmd\

Create C:\l4d2\

Step 2: Download SteamCMD and extract it to C:\steamcmd\

Step 3: Open command prompt and navigate to the SteamCMD files that we extract in step 2

Click Start > Type: CMD > right click on command prompt > Run as Administrator

In the black command window type: cd C:\steamcmd

Step 4: Run steamcmd, login, and download the left 4 dead 2 server files

steamcmd

login anomymous (or your steam username)

force_dir_install C:\l4d2 (This will change the download directory to the one we created for left 4 dead 2)

This will take a bit to update and depends on your download speed.
