why command and conquer work on windos 10

@Nicolasstaniford

"Command & Conquer" is quite a lot of games. Which specific one(s) are you having trouble with?

For the record...

Command & Conquer 1, Red Alert 1 and Tiberian Sun have all been upgraded with community-created unofficial patches that fix a lot of their bugs and compatibility problems. For Red Alert 2 there's a more general patch that solves a lot of its graphics problems. You can find them here:

Command & Conquer 1:

• Nyerguds' C&C95 v1.06c revision 3 patch (which also adds bonus missions originally exclusive to the Playstation and Nintendo 64 versions of the game)

Red Alert 1:

• Funkyfr3sh's automatic Red Alert 1 patcher/installer
• Nyerguds' main.mix cleanup for TFD/TUC (Not really needed, but cleans up about a gigabyte of unnecessary files in the RA1 folder. Unpack in the game folder, run "patch_main.bat", let it finish, and then delete the files you extracted.)

Tiberian Sun:

• Funkyfr3sh's Tiberian Sun patch

Red Alert 2:

• The graphics system patch DDWrapper is known to solve the "black screen" issue.
  Download the zip file and extract "ddraw.dll" and "aqrit.cfg" into your game folder. Then, open the configuration file "aqrit.cfg" in Notepad, change the "ForceDirectDrawEmulation" option to 1, save the file, and the game should work.
