Most programs created for earlier versions of Windows will work in this version of Windows, but some older programs might run poorly or not at all. You can run the Program Compatibility Troubleshooter on most programs to detect and fix common compatibility problems.
Don’t run the Program Compatibility Troubleshooter on antivirus programs, firewall software, backup software, disk utilities, or on system programs that came with Windows. This might cause data loss or create a security risk.
Swipe in from the right edge of the screen, then tap Search.(If you're using a mouse, point to the top-right corner of the screen, move the mouse pointer down, then click Search.)
Enter run programs in the search box.
Tap or click Run programs made for previous versions of Windows, then tap or click Next.
Select the program you want to fix. Or If you can't see the program in the list, select Not Listed.
Tap or click Next, then follow the instructions in the troubleshooter.
You can also run the Program Compatibility Troubleshooter from your desktop. Press and hold or right-click the program's icon or shortcut on your desktop, then tap or click Troubleshoot compatibility.
The Program Compatibility Troubleshooter can fix problems that can't be detected or fixed by the Program Compatibility Assistant.
If the troubleshooter can't fix the problem, you can try changing compatibility settings manually.
These steps will not work with programs that are part of Windows, like Paint or Windows Media Player, or with apps you get from the Windows Store.
Enter the name of the program in the search box, press and hold (or right-click) the search result, and then tap or click Open file location.
Press and hold (or right-click) the program icon, tap or click Properties, and then tap or click the Compatibility tab.
Select one or more of the settings (see the table below for more info).
If you want to apply the settings for that program to all accounts on the PC, tap or click Change settings for all users.
You might be asked for an admin password or to confirm your choice.
When you've finished, tap or click OK.
