Change Compatibility Mode Settings for Apps in Windows 10
Windows 10 supports plenty of apps created for earlier versions of Windows. However, some older apps have issues with scaling, especially if you have a high resolution display like Full HD or 4K. Other apps like games can have issues or not start at all if they cannot detect the version of Windows for which they were created. Compatibility mode settings in Windows 10 are intended to solve these issues for you.
