Windows XP's Freecell WILL RUN on Windows 10. You simply need to copy FREECELL.EXE and CARDS.DLL from a Windows XP computer. The XP path to CARDS.DLL is C:\windows\system32\. Put both files in the same folder on your Windows 10 computer, but DO NOT put them into the System32 folder because they may not be compatible. To run the program, just double-click the “Freecell.exe” file. You can create a shortcut to the file on your desktop or pin the program to the taskbar or start menu. That's it.
