Well this is new. Suddenly I don’t have an adapter / graphics card to run modern warefare 2.

Step 1: Update drivers.

Step 2: Reboot

Hmmm same issue. No supported DXGI adapter were found, please verify that your graphics card is within the minimum requirement and that your drivers are up to date.

Step 3: Check for updates in Battle.net

Looks like we were already up to date.

Step 4: Scan and repair

The scan seemed to have corrected the issue. Special thanks to TheSneezingMonkey for his video help.
