Windows 7 Calculator for Windows Vista

By Taimur Asad | November 15th, 2008

Among lots of other stuff, one of the main focus of Microsoft with Windows 7 has been to give a facelift to the native Windows applications like Paint, Calculator and WordPad which haven’t been updated since Windows 3.x days. So for those of you who weren’t lucky enough to attend this years PDC and get your hands on Windows 7 Pre-Beta can now get the new Calculator application from Windows 7 M3 Build 6801 and run it on your existing machines running Windows Vista.

Here is how it looks under Windows Vista:

Instructions on How to replace Windows Vista Calculator with Windows 7 Calculator:

Step 1: Download Windows 7 Calculator from here.

Step 2 (Optional): Navigate to C:\Windows\System32\ & C:\Windows\System32\en-US\ to backup the files calc.exe and calc.exe.mui respectively. Do not skip this step as you might want to revert back to the original Calculator just incase you mess up something when replacing the files.

Step 3: Now copy and replace calc.exe in C:\Windows\System32\ & calc.exe.mui in C:\Windows\System32\en-US\ with the ones you just downloaded. Make sure you are logged in as an administrator account and have given your account full permissions for the files you are replacing.

That’s it! You can now enjoy fully functional calculator from Windows 7 in Windows Vista.

Unbelievable! Redmond still has not increased the size of the "minus" icon so that it is not so easily confused with the decimal point! How many decades will it take??? Granted, if you're sitting up straight with your head a foot from the screen, you'll be able to discern which is which. But real-life users aren't always sitting up.

:idea: oh and also, after you copy it into the system, right click the exe file and Pin it to the start menue, and it works fine side by side with the vista one, and btw its great, i'm doing averages for report cards, and its just great to see the last thing you entered. :!:

Same problem as Greg :(, any sollutions?

My computer would not let me copy calc.exe into the c:\windows\system32 directory to replace the existing calc.exe.
"You need permission to perform this action" - was the error message.
Sadly I am the only administrator/user on my computer. Nonetheless, I ran "net user administrator /active:yes" and restarted to login to the administrator account. Still it would not let me replace Calc.exe. Please help me. Thank you.

Btw: the calculator looks good and it works well when I run it from the original folder (unzipped ofc).

It is a nice new calculator and I like how it saves history like the printing calculators from back in the day. In the end it is still just a calculator and I am not that excited about it.

Looking forward to see the new notepad. 8)
