Despite being a powerful, modern operating system, Windows 10 and 11 still support running many old MS-DOS programs — with the right tools. Whether you’re trying to use a classic business application, play retro games, or run legacy utilities, there are several reliable methods available.

In this guide, we’ll walk you through:

• ✅ Why DOS programs don’t always work
• ✅ The best ways to run them on modern systems
• ✅ Step-by-step instructions for each method
• ✅ Tools that make it easy and safe

Let’s get started!

❓ Why Don’t DOS Programs Work Directly?

Modern versions of Windows no longer run on real-mode DOS, but instead on the NT kernel, which is more secure and stable — but also incompatible with older software.

Common Issues:

Problem	Explanation
No Real Mode Support	DOS apps require direct hardware access, not allowed by default
16-bit Code Blocked	64-bit editions of Windows cannot run 16-bit applications
Protected Memory	Apps can’t directly access memory like they used to

⚠️ This means even if a DOS program launches, it may crash, freeze, or behave unpredictably.

💾 DOSBox	Excellent	Easy	Games & general use
🧰 Virtual Machine (VM)	Very good	Moderate	Business apps & full OS control
🖥 NTVDM (32-bit only)	Limited	Easy	Simple EXE-based tools
🔁 Compatibility Mode	Rarely works	Easy	Quick tests only
🐧 WSL + DOSBox	Good	Advanced	Devs & Linux users

🧰 1. Use DOSBox – Best for Most Users

DOSBox is a free, open-source emulator that recreates a DOS environment. It’s perfect for playing classic DOS games or running legacy software.

✅ Steps to Install and Use DOSBox

1. Download DOSBox

• Visit https://www.dosbox.com
• Download the latest Windows version

1. Install DOSBox

• Run the installer
• Accept defaults

1. Set Up a Folder for Your DOS Programs

• Create a folder, e.g., C:\DOS
• Place your .EXE, .COM, or .BAT files there

1. Mount the Folder in DOSBox

• Open DOSBox
• Type:
  mount c c:\dos c:

1. Run Your Program

• Type the name of the executable:
  myprogram.exe

🎮 Tip: Works great for classics like Doom, Prince of Persia, and Commander Keen.

🧪 2. Run DOS in a Virtual Machine (VM)

If you need full control over the environment or are using hardware-dependent software, install a real DOS OS inside a virtual machine.

✅ Steps to Set Up DOS in a VM

1. Download a VM Tool

• Free options:
  • VirtualBox
  • VMware Player

1. Get a DOS Distribution

• Options:
  • FreeDOS
  • Original MS-DOS (if licensed)

1. Create a New VM

• Choose “Other” or “DOS” as the OS type
• Allocate ~128MB RAM and a small virtual hard disk (~2GB)

1. Install DOS

• Mount the ISO or floppy image
• Follow installation steps

1. Copy and Run Your DOS Programs

🧑‍💼 Best For: Running legacy business software, industrial tools, or testing environments.

🖥 3. Use Windows’ Built-in NTVDM (Only on 32-bit Windows)

Older 32-bit editions of Windows include NTVDM (NT Virtual DOS Machine), which can run many DOS programs directly.

✅ How to Enable NTVDM

1. Enable Legacy Components (on 32-bit Windows only)

• Go to Control Panel > Programs > Turn Windows features on/off
• Check Legacy Components > NTVDM

1. Run Your DOS Program

• Double-click the .exe file
• Or launch from Command Prompt

⚠️ Note: 64-bit Windows does not support NTVDM, so this method won’t work on modern PCs.

---

🔁 4. Try Compatibility Mode (Sometimes Works)

Some simple DOS-based programs might run under Compatibility Mode.

✅ Steps:

1. Right-click the .exe file > Properties
2. Go to Compatibility
3. Check Run this program in compatibility mode for: > Select Windows XP (Service Pack 3) or earlier
4. Also check Run as administrator

⚠️ Warning: This often doesn’t work for complex or hardware-dependent apps.

🐧 5. Use WSL with DOSBox (Advanced Option)

If you’re using Windows 10/11 with WSL2, you can run DOSBox inside Linux.

✅ Steps:

1. Enable WSL:

   wsl --install

2. Install a Linux distro (e.g., Ubuntu) from the Microsoft Store
3. Open WSL and install DOSBox:

   sudo apt update
   sudo apt install dosbox

4. Copy your DOS files into WSL home directory
5. Launch DOSBox and mount:

   dosbox
   Z:\> mount c ~/dos
   Z:\> c:
   C:\> myprogram.exe

🧠 Pro Tip: This is useful for developers or power users who want a Linux/DOS hybrid setup.
