In Windows 10, if you want to set up a compatibility mode for a specific application so that it can emulate an earlier version of the Windows environment, you can do so by following these steps:
First, find the executable file (.) for the program you want to set compatibility withexe）。This is usually located within the program's installation folder.
Right-click on the executable file of the application and select the "Properties" option.
In the properties window that opens, switch to the Compatibility tab.
In the "Compatibility" tab, you'll see the "Compatibility Mode" option. Tick the "Run this program in compatibility mode" checkbox.
Select the version of Windows you wish to emulate from the drop-down menu. You can choose from Windows 95 to the latest Windows version.
In the same tab, you can also set other compatibility options, such as running the program with administrator privileges, changing high DPI settings, and more.
For example, checking "Run this program as administrator" gives the required permissions to applications that require higher permissions.
When you are done with the settings, click the "Apply" button and then "OK" to close the properties window.
This way, you have set up a compatibility mode for the program. The next time you launch the program, Windows 10 will try to run it with the compatibility settings you specified. If the program previously failed to run or had problems, these settings may help resolve compatibility issues.
Please note that some programs may not work properly even in compatibility mode, especially those older software that is not compatible with the current Windows 10 system architecture. In this case, it may be necessary to look for an updated version or alternative to the software.
