There are some old DOS applications that you just can't afford to lose (or games you still like), and Windows 10 lets you keep them. Here's how.

Some programs written for even older versions of Windows may work on Windows 10 without an issue. For other pieces of software, it may take some additional work to get it up and running.

Some older software depends on old Windows libraries that are no longer included with Windows 10. Since Windows XP, all versions of Windows no longer run on top of DOS.

If you're beyond basic Windows 10 customization -- and comfortable working in the Registry or the Command Prompt -- you've probably noticed that you can't run programs as an administrator by default.

Using the Windows Subsystem for Linux (WSL), you can launch Linux applications directly in a Windows 10 command prompt or PowerShell prompt.
