One way to do the currently not functioning os.cpus() in node.js on windows.

cpus.js

var exec = require('child_process').exec;

child = exec('python cpus.py',
  function (error, stdout, stderr) {
    console.log(stdout);
});

cpus.py

try:
    import _winreg as winreg
except ImportError as e:
    import winreg
key_path = 'HARDWARE\\DESCRIPTION\\System\\CentralProcessor\\'
key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, key_path)
index = 0
s = '['
while True:
    try:
        winreg.EnumKey(key, index)
        sub_key = winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, key_path + str(index))
        mhz = winreg.QueryValueEx(sub_key, '~MHz')[0]
        model = winreg.QueryValueEx(sub_key, 'ProcessorNameString')[0]
        s += '{"model":"' + model + '","speed":' + str(mhz) + ',"times":{}},'
        winreg.CloseKey(sub_key)
        index += 1
    except WindowsError as e:
        break
winreg.CloseKey(key)
s = s[0:-1] + ']'
import json
print(json.dumps(json.loads(s), indent = 4))
