How to Run Compatibility Mode in Windows 11: A Step-by-Step Guide

By / October 4, 2025

Have you ever tried running an old application or game on your new Windows 11 PC, only to find that it doesn’t work properly—or doesn’t launch at all? Don’t worry; you’re not alone. Many older programs were designed for previous versions of Windows, such as Windows 7, Windows 8, or even Windows XP. Luckily, Compatibility Mode in Windows 11 allows you to run these older applications smoothly.

In this guide, we’ll cover what Compatibility Mode is, why it’s important, and how you can enable and configure it step by step.

Key Takeaways

  • Compatibility Mode helps older apps and programs run on Windows 11.

  • You can enable it from the Properties menu of a program or use the Compatibility Troubleshooter.

  • Windows 11 allows you to emulate older versions of Windows, such as Windows 7, 8, or Vista.

  • You can also adjust display, scaling, and administrator privileges for better performance.

What is Compatibility Mode in Windows 11?

Compatibility Mode is a Windows feature that allows you to run older software designed for previous versions of Windows. It adjusts system settings to mimic the environment the program expects, making it more likely to run correctly.

Think of it as giving your old program a “time machine” that tricks it into thinking it’s still running on Windows 7 or Windows XP.

Why Do You Need Compatibility Mode?

Not all older apps have been updated for Windows 11. You might need Compatibility Mode if:

  • A program refuses to install or open.

  • The app runs but crashes frequently.

  • Fonts, graphics, or menus look broken.

  • A game runs with glitches or refuses to load.

  • You need to use legacy business software.

Method 1: Run Compatibility Mode from Program Properties

The easiest way to enable Compatibility Mode is through the program’s properties.

Steps:

  1. Right-click the program shortcut or .exe file.

  2. Select Properties.

  3. Go to the Compatibility tab.

  4. Under Compatibility mode, check Run this program in compatibility mode for.

  5. Select the Windows version (Windows 7, 8, Vista, or XP) from the dropdown.

  6. Click Apply and then OK.

👉 Next time you run the program, it will launch in Compatibility Mode.

Method 2: Use the Compatibility Troubleshooter

If you’re not sure which settings to use, let Windows decide automatically.

Steps:

  1. Right-click the app shortcut or .exe file.

  2. Select Troubleshoot compatibility.

  3. Windows will launch the Program Compatibility Troubleshooter.

  4. Choose either:

    • Try recommended settings (Windows will pick the best option).

    • Troubleshoot program (manually choose the problem).

  5. Test the program and click Yes, save these settings if it works.

Method 3: Run Programs as Administrator in Compatibility Mode

Some apps may need administrator rights to run properly.

Steps:

  1. Right-click the app and select Properties.

  2. Go to the Compatibility tab.

  3. Under Settings, check Run this program as an administrator.

  4. Click Apply, then OK.

Advanced Compatibility Settings in Windows 11

In the Compatibility tab, you’ll see several other useful options:

Setting What It Does When to Use
Reduced color mode Forces the app to use limited colors For very old software with display issues
Run in 640×480 screen resolution Forces low resolution For apps designed for old monitors
Disable fullscreen optimizations Prevents Windows from altering display For games with performance issues
Change high DPI settings Fixes blurry text or scaling issues For apps that don’t scale well on high-resolution displays

Method 4: Use Command Prompt for Compatibility Mode

Advanced users can apply compatibility settings using Command Prompt.

Example command:

compatadmin.exe -run "Program.exe" -set:Win7

This sets the program to run as if it were on Windows 7. (Note: requires the Application Compatibility Toolkit).

Method 5: Use Registry Editor (Advanced Users)

For power users, you can configure compatibility via the Windows Registry.

⚠️ Warning: Editing the Registry can be risky. Always back it up before making changes.

Steps:

  1. Press Windows + R, type regedit, and press Enter.

  2. Navigate to:

HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers

  1. Right-click → New > String Value.

  2. Enter the program path (e.g., C:\Program Files\App\app.exe).

  3. Set value to the compatibility mode (e.g., WIN7RUNASADMIN).

  4. Restart your computer.

Method 6: Run Compatibility Mode for Installers

If an older program refuses to install:

  1. Right-click the installer file (setup.exe).

  2. Select Properties → Compatibility tab.

  3. Enable Run this program in compatibility mode for.

  4. Choose an older Windows version.

  5. Run the installer again.

When Compatibility Mode Won’t Work

Sometimes, Compatibility Mode may not solve the problem. This usually happens if:

  • The program is 16-bit (Windows 11 only supports 32-bit and 64-bit).

  • Drivers or hardware dependencies are missing.

  • The program requires outdated frameworks.

👉 In this case, you can try running the app in a virtual machine using software like VirtualBox or Hyper-V.

Compatibility Mode vs Virtual Machine

Feature Compatibility Mode Virtual Machine
Ease of Use Very easy More complex
Performance Runs natively Slower (emulated environment)
Best For Simple older apps Legacy systems & software
Setup Time Quick Longer (requires OS install)

Best Practices for Using Compatibility Mode

  • Always try the latest version of the software first.

  • Run the troubleshooter if you’re unsure which settings to use.

  • Use administrator privileges for older apps.

  • Avoid using Compatibility Mode for modern apps (may cause issues).

  • If needed, consider virtual machines for very old programs.

Conclusion

Now you know exactly how to run Compatibility Mode in Windows 11 step by step. Whether it’s through Properties, Troubleshooter, Registry, or advanced settings, you have multiple ways to get older software running on your PC.

For most users, the Properties method or Troubleshooter will do the job. But if you’re dealing with stubborn legacy apps, you may need advanced tweaks—or even a virtual machine.

With Compatibility Mode, you don’t have to give up your favorite apps and games just because they’re old!
