all i can think of is sadly a joke
1. uninstall win 10 or put it away on a HD in a closet somewhere until games and dx12 matter and ms cares about small stuff like, a working os, a working browser, old games that used old copy protection to not work, to work again, drivers for small things like oh controllers ...esp windows made ones.. wtf.. ms you suck
2. install win 7 or xp pro.
3. enjoy old gaming..
sorry again, once you upgraded from 7 to 10 it should list apps that will be effected, its best done on a clean drive.
and even if its not in the list its not likely win10 saved those.. as they branched into MYDOCS which isnt the same anymore.
id have to look into ags and saved games and the mydocs files,
there is a way to tell for sure but.. you wont like it
thats roll back to win 7.. and see if they are there..
or start over the game from scratch (its not that long of a game honestly the best option if you cant recover the data)
heck only option.
4. win 10 sucks.. truly.. it will be awesome only for a few AAA dx12 titles and thats about it for the next 2-5 years
ickkkyyy
my win 10 pro is ssd is sitting in my closet. never to be used spit spit
