We have updated the Games for Windows Live installer in the installation package. If you have a Windows 10+ machine, this will return the Game for Windows Live features as long as you are logged into your Xbox account. You can do this through the Xbox Game Bar. There is no way at this time to return this functionality for Windows 8 or lower operating systems.
