Thread: Execute application in compatibility mode in Windows 7

I upgraded OS on PC from XP to Windows 7. But now some applications are not working. Someone told me to run application in compatibility mode. So please tell me how to run application in 800x600 compatibility mode in Windows 7. Any help will be appreciated.

For this refer Windows help by pressing F1 key on keyboard. In search box, type "Compatibility mode" and press enter. Do all steps suggested to enable compatibility mode.
