Not to my knowledge, I think they still work off GPDs though, since the 360 can list the games separately (For example I have GTA IV, and GTA IV(PC)).Is there anything you can do for GFWL games or not really? I did find one thing but I thought GFWL didn't exist anymore but it does partially, I don't think there are any free games anyway.
The GFWL store has been closed for years now, you can still find the links on Xbox.com for some games like Microsoft Flight, but a majority of the games have long since been delisted and links removed. True Achievements has been a god send for finding the ones that can still be downloaded.
People can still redownload old GFWL games too, and since you can technically still find cracked copies and make an offline account with the GFWL GPDs, it may be possible to rip them to a legit account. (I don't condone this, though).
There's a load of delisted Arcade games, Apps etc that are neigh impossible to find, 1V100 being one of them, games like Full House Poker, the entire Kinect app platform with the weird mini games, and Kinect Labs (Of which I am still trying to find a download of them all again)...
You've also got the "Internal" achievements like the 360 launch, Kinect Launch/beta tester 0G achievements, and also the Xbox Live Labs ones (Which people say were used to improve the ban algo since it scanned and sent all console and account data to a temp server)
