To run old applications in Windows 10 it is possible to set the compatibility options under File Properties ➞ Compatibility.
This is a per user setting stored in the registry, so it will only work for executables on the local hard drive not on a network drive. It also will not work for protected files delivered as part of the OS such as notepad.exe. It is possible to make a copy of a system file and set the properties on that, or to create a shortcut and set the shortcut properties.
All of the settings in the Compatibility tab can also be set directly via the registry:
or for all users:
It is important to specify the options in the correct order, the sequence in which the options are displayed in the compatibility tab.
