Hi , welcome to the forum 
To get the server working in windows :
-
Install nodejs (32 bit or 64 bit)
Windows 32-bit Installer: https://nodejs.org/dist/v0.12.9/node-v0.12.9-x86.msi
Windows 64-bit Installer: https://nodejs.org/dist/v0.12.9/x64/node-v0.12.9-x64.msi
-
confirm that your nodejs install is working
type “node -v” or “nodejs -v” in the terminal it should return the version on installed node
type "npm -v " next it should return the version of npm
-
if the above steps went well , then go to Desktop & Laptop Computer 2 and do steps 1 - 5 and it should work
Hope this helps , do ask if you need any help
