Get Calculator from Windows 8 and Windows 7 in Windows 10

In Windows 10, Microsoft ditched the good old calculator app and replaced it with a new Modern app, which we wrote about recently here: Run Calculator in Windows 10 directly. Many people are not happy with this change because the old Calc.exe loaded faster, and was more usable for mouse/keyboard users. If you would like to get the classic Calculator app back in Windows 10, it is possible. In this article, we will take a look at the Old Calculator for Windows 10 program which will allow you to get Calculator from Windows 8 and Windows 7 in Windows 10.

Update: a new version of Old Calculator is available. In this version, I made it possible for the old calculator to "survive" after sfc /scannow, Windows Update and so on. No system files will be replaced any more.

To get Calculator from Windows 8 and Windows 7 in Windows 10, you need to do the following things:

  1. Download the setup program for Old Calculator for Windows 10 from here: Old Calculator for Windows 10
  2. Run the installer. It will look like this:
  3. Follow its steps. After it finishes, you will find the good old Calculator app shortcut in the Start menu:
  4. After you launch it, you will get the familiar application:

You are done. The Calculator app will be revived completely, e.g. you will be able to launch it as "calc.exe" from the Run dialog or from the taskbar search box or from Cortana. It will have the same interface language as your operating system. If you will decide to revert to the Modern Calculator app, just uninstall the Old Calculator from the Settings app\Uninstall a program, see the following screenshot:


That's it!

            I had the same issue. Just type calc.exe on the command line and the old scientific calculator will run. It is installed, but it does not show up above All Apps on my Windows10 revision.

            Great App Sergey. Keep up the good work. PeterA

      Not legal? Well, then get Microsoft here. No one care’s and there isn’t a damn thing Microsoft can do about it, especially when users demand particular legacy applications with Windows to function and Microsoft ignores those requests made by experienced users. You’re just another one of those fanboy Microsoft dweebs who believes everything Microsoft does is perfect. Don’t talk about legal when in fact Microsoft has from the beginning stole things. OS/2.

    The next day after I installed this, Windows 10 replaced the new calculator — even though it does not function, as I have disabled UAC. Any way to get this to stick permanently short of disabling Windows Update?

        Thanks Sergey! We’ll see if it sticks, but I really enjoyed saying “Yes” to all of those “You are about to change or remove permissions on system files…” prompts. Heh-heh-heh.

        To be clear, I took ownership of it and disabled inheritance, which removed all existing permissions, and then I added my own permissions back onto it.

    Маленькая проблемка с Old Calculator. Все хорошо, но после установки обновлений Windows 10 калькулятор самопроизвольно заменяется на новый (метро). Изменяются и ярлычки. Причем они отличаются от нового, но все равно запускают новый. У вас есть рекомендации, как исправить? Можно, конечно, деинсталировать и установить снова, но это до первого обновления. Пробовал.

    Hello, thank you for the excellent work. Maybe you can help me with a quick issue. In prior versions of windows, if you used executed the program using your keyboard short cut you could immediately start typing in the calculator. Now in windows 10 if you execute the calculator you then have to click on the open calculator before you can type. Huge drag as though does not sound time consuming, when you need to use the calculator often it is a hassle, especially trying to break the habit of executing the calculator and trying to immediately use it only to be throwing out blanks lol. Thanks!1

    By the way, is there any way to manually define the GUI language?
    My windows is in PT-BR. During install, I manually selected English. But when I run calc.exe, everything is in Portuguese… So it seems that the language setting selected on install only applies to the installer, not to the program itself.

    Hi,

    I have tried it and the installer says all fine, but still the Win 10 Calculator will be shown / used.
    Different reboots and also no change.

    The style isn´t what matters for me. But that you can´t handle the Win 10 Calculator like the Win 7 one (f.e. Bitmanipulation by clicking on the Bits are no longer availabe)

    Any Idea ?

    Thank you!

    My new Win10 calculator app is “dumbed” down a little too much for my taste and has this nasty effect where I have to click on it before I can make key entries. This version is simple, allows key or click inputs immediately upon launch, and has the history/memory feature I found useful. The Microsoft Plus calc was more like the default app with a new skin, and the default skin it had was revolting imho. I’d recommend your solution to anyone who asked.

    I noticed someone else asked about this, but I thought I’d ask again as I saw no response. Does anyone know why when you launch the calculator (new or old) in Windows 10 it is not immediately active? When I’m in a random program (a browser), and I hit my keyboard button for the calculator and immediately start typing (as I was able to to in ALL prior versions of Windows), it’s only annoying that the calculator is not active and my numbers are going nowhere. However, when I’m using Excel and I punch the calculator button and start calculating away only to look up to find I’m editing a cell in Excel because the calculator is not active on launch…this REALLY concerns me. It could cause serious issues in my worksheets if I happen not to notice. I know it’s Windows fault, not the author’s (at least this calculator can be used right away! the Win10 calculator days 5-10 seconds to allow typing – I might as well spend the time to find my real calculator!), but was hoping to ask the question here to see if anyone has an idea how to fix?

    Hi Sergey,

    Thank you for the great work! Quick question: In old calculator, when I pressed the calculator shortcut on my keyboard, if it was open, it would only switch to it instead of opening a new one. Now every press results in a new copy of the calc.exe running. Is there a way to make it work like it used to?

    Thanks

    Reply
    1. Sergey Tkachenko Post author

      Hmm, I have no idea.
      Quite possible that calc.exe (the old one) is looking for such process running in Windows. If it found calc.exe, it just switch to the running one.
      In our case, the old calc.exe is named calc1.exe. It can’t find calc.exe running, so this can cause those multiple instances.
      It is just my guesses, needs to be checked.

        After taking ownership of the calc.exe and replacing it with your file it would not run. I remember the old version of your calculator used to take over instead of being number 2. Is it possible to download that somewhere?

            The previously mentioned problem that now every time I press the calculator shortcut on my keyboard it keeps opening a new copy of the calculator. The previous version just switched to the already opened version. I understand that the previous version overwritten some system files and that it would not make it past an upgrade but I am happy to keep reinstalling it in exchange to have it work in a way that makes a lot more sense to me. :)

    As per a few comments when I click my CALC button on the Windows keyboard it brings up Old Calc but you have to click to regain focus.

    Also another issue – though I was able to powershell the old one off the taskbar, there is no “pin to taskbar” option for this.

    Huge thanks for the port!

    Correction: My work PC (Enterprise) just received the WIndows 10 Anniversary update and I have lost all PIN/UNPIN to taskbar functionality. The calculator focus problem appears to be intermittent – sometimes it works (press calc button or click program) and sometimes it does not.

    At home (Pro) I have not received that update and both pinning and focus appear to work fine. I can press the calculator button and focus is correct. (OTOH, focus could be intermittent and it has just been working any time I need it)

    Excellent job but there is a major problem:
    2+5*6=42 in standard and is wrong
    2+5*6=32 in scientific and is correct.
    Standard mathematics and scientific is the same, first multiplications and then addition
    Maybe Microsoft want’s to bring new theory in mathematics (or arithmetic)
    I don’t know if your old Win7 program is just cosmetic interface of Microsoft’s program but if possible please upgrade. Anyway, let’s remember the Microsoft same wrong mathematics in Access 2003, without the special patch our company had trouble calculating prices.

    I agree that the new “look” of the calculator isn’t great, but all you need to do is resize it and it looks very much like the old calculator. The new size even stays when closed and reopened.

    As for Ovidiu’s complaint about the math issue (2+5*6=42 in standard, but 32 in scientific), the same is true no matter if you are using the Win10 calculator or Win7 calculator. Standard performs operations from left to right. Scientific actually looks that the problem and figures out that multiplication and division should be done prior to addition and subtractions.

    This is an odd thing with this old calculator.

    Since updating my computers to the latest Fall Creators Update (1709) Old Calculator opens automatically every time I boot.

    Useless to me, I can’t drag it anywhere. I have lots of stuff on my desktop open at various times so need to be able to drag it to another position on the screen. But that capability isn’t there. Going to stand in a corner and sulk. So there!

      Just delete its files and the start menu shortcut.
      Then delete the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\calc.exe
      It doesn’t change anything else.

    Thank you for the fast reply.
    Unfortunately the key HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\calc.exe
    doesn’t exist(tested on three machines).
    Also by files you mean the calc.exe located in Windows\System32 and the shortcuts or there are some other files which have to be deleted?

      I mean the Windows\System32\calc1.exe file and its mui files in Windows\System32\en-US\calc1.exe.mui

    Thank you for your efforts to make Windows better!
    I installed this old looking Calculator, it works fine just it is a bit too small and I don’t have option to resize it.
    It is at the smallest size, I cannot drag edges to enlarge it nor I have active maximize button in the upper right corner. There is just one to close and one to minimize..
    https://prnt.sc/p875rw
    Any ideas how can I make it a bit larger?

      Additional note: I don’t have Tablet mode enabled, I use Windows 10 Enterprise ver.1809. It’s installed about 3 weeks ago or so. Only thing that I changed is “colored Title bars” and Win 7 style Calculator, via Winaero Tweaker.

        Add.note 2: Since I installed Oldstyle calculator, Windows Calculator disappeared from the list of Windows Apps in Settings, so I cannot reset it.. I now tried to revert to the Modern Calculator app, so I uninstalled the Old Calculator from the Settings app\Uninstall a program, but calculator still looks the same, as on screen shot above – looks like oldWin 7 calculator, with small size that I can’t change..

    Thanks a lot! I need the old school calculator since the windows 10 one didn’t let me edit the calculating history

    I had to add the shortcut to the start menu manually, and it has an ugly icon. However, it’s great to have it back!

      What is the path you have installed it to?
      What happens if you run the calc1.exe file directly?

    My solution for making this work in start menu after all the updates/creators updates/etc.

    Create batch file called Calculator (Classic).bat

    inside batch file only need 1 line:
    start calc1

    save to documents or such.
    add shortcut to batch file in “C:\ProgramData\Microsoft\Windows\Start Menu”

    If you’re feeling fancy, change the icon for the shortcut to match the file calc1 in system32

    Hi, the calc looks awesome, but I cannot install it as I do not have admin rights on my notebook.
    Is there a portable version without installer?
    Thanks!

        Hi, thank you very much! I used this calc, it’s realy nice and usable.
        I would like to have a portable version too, for my office computer. How can I get it?

          Extract the installer with 7-zip.
          Place the files as follows.
          c:\calc_portable\
          en_US\
          ru_RU\
          calc1.exe

          Run calc1.exe
          Enjoy.

    This won’t install on windows 10 1909 and 20h1. Microsoft actively started to prevent old applications from windows 7 with certain mui’s to install on /system and/or /SYSwow (The same on old games from windows 7). To complete the install, you will need to install this, disable windows defender and extract the MUI’s with 7z from the exe, and then manually extract the calc1.exe.mui files from the installer (in my case $TEMP/System32/ and select the locale that matches your OS, english is en-US (or en-GB if you are form UK), then copy manually to C:\windows\system32\en-US (or en-UK).

    Even if you get this file from an old win7 installation, Windows defender will try to prevent the installation of the mui for some reason. Once installed, you can reenable defender, and it will not bother anymore, even when doing a system scan, but doing an SFC can delete it.

    Thanks for keeping this updated. The functionality is great and better than the W10 calc which has gotten even worse over time. I mean you can’t even select a history state, and you have to learn where to offset the location of your right-click to copy and paste.

    Only one problem – the Old Calc is very small on a large monitor or a high resolution or both.

    The new one is fully resizable and adaptive. I understand that may be near impossible to recreate or code in the old calc – but can we simply get a large size version? About twice the size or maybe 75%

    thanks!

    Are you able to make a Linux/Ubuntu version of the Windows 7/8 calculator, or do you have any suggestions on how to run it in Linux? I tried with Wine, but I couldn’t get it to run. Thanks!
