Get Old Classic Calculator in Windows 10

Windows 10 introduces the Universal Windows Platform (UWP), which provides a common app platform for every Windows 10 device. This also means that your favorite classic Win32 desktop applications are going to vanish one by one over time, just as already happened to the Sticky Notes and Calculator applications. And Paint appears to be the next, which will be replaced by Paint 3D.

This post tells you how to get back the old Windows 8 classic Calculator desktop program in Windows 10.

Step 3: Move the corresponding MUI file (calc1.exe.mui) to the folder that corresponds to your Operating System language. For example, if using English (United States), copy the MUI file from “en-US” in the source folder, to “C:\Windows\System32\en-US” folder.

I’ve also included several MUI files for other languages. Here is the list of language MUI files enclosed in the zip file.

Step 4: Run the REG file named register.reg. This REG file (a plain-text file) sets a registry key so that when you run calc or calc.exe from Run dialog, it launches the classic Calculator instead of the Modern or UWP Calculator app.

For your information, the REG file creates the following App Paths key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\calc.exe

And points it to C:\Windows\System32\calc1.exe

That’s it! You can now enjoy your classic Windows 7 / Windows 8 Calculator.

How to I remove Classic Calculator?

To reverse the changes, run the “undo.reg” file. Then delete calc1.exe from Windows\System32 directory. Also, delete calc1.exe.mui from the corresponding language directory, such as Windows\System32\en-US.

  1. I’m grateful for this solution of you. That’s unbelievable !

    p.s: It’s 11 August 2017 – currently running Turkish Windows 10 x64 with the latest updates. And this solution worked for me.

    p.s for admin: I’m ashamed that you blocked users from Turkey. I just wanted to say thank you, so I turned on my vpn. Can you do us a favor and stop block users from Turkey? Please?
