Windows 10: Cannot use programs/games after upgrading windows 8.1 to windows 10

I have installed new windows on the C drive and when the computer launched I realized that I cannot play games which were previously installed both on C and D Drive. After the upgrade to windows 10 I have installed battlefield 2042 and It worked just fine but I cannot lauch the games I had before the upgrade.

When did AMD release DX12 drivers?

 

How to reinstall Windows 10 if my computers used the free upgrade from 7 and 8?

Will windows 10 still accept the license keys from 7 and 8 now if I reinstall my computer?

Does Microsoft keep a list of users who upgraded to Win 10 using their 7 and 8 keys so that when users need to reinstall windows 10 the old keys would work?

Do I need to call in Microsoft to ask them to activate my Windows 10 when I give them my win 7 keys?

Both computers are laptops. The windows 7 machine had the serial printed on the back, and I needed to enter that when I upgraded to 10. The windows 8 machine had the serial built in inside its boot system so I didn't need to enter the key when I upgraded to 10, but I did manage to write down the keys using a fetcher program.
