After that, type the following command in Command Prompt and press Enter key:

  1. Uninstall and reinstall on my laptop. It just wouldn’t open today on the laptop but on the desktop it was fine. Did some windows updates on both today.

  2. I’ve been to about 15 other web sites including Microsoft. Solution #1 was the only thing that worked! thanks, Thanks, THANKS!!!!!

  3. Super nice !! Calculator’s working fine now :))
    Option 1 did if for me

    Now my Store is not opening showing error 0x80072EE7 🙁

    But i remember a similar repair option using powershell , similar to option 1 on this post about the calculator , let me search here on the website for it, but if you have it please sharethe link with me so i can access it quickly

    But thanks a lot for the help, calculator is everything to me lol..

  4. Calculator, Snip&Sketch, 3DViewer, Paint3D and MSPhotos had all gone bad after patches received 8-12th Feb 2021. Ran the Reset option as described in this article and they are all good again now.

  5. I’m with ‘Mike Rowe Soft’

    None of the above methods worked for me. Calculator stopped working after latest update pushed to my pc by IT.

    Another note, Notepad also stopped working as well. I don’t care about updates when they fix an issue but when there is an update and all I encounter are new issues, that’s where I have a problem.

    The workarounds are unacceptable. These are two applications that have been on Windows for as long as I can remember.. and now neither one works after an update? UNACCEPTABLE

  6. Many Thanks. Option two was the first option that worked for me.
    As instructed I uninstalled it then opened Windows Power shell as Administrator and copied and pasted the code line shown. It did take a little bit of time (time to wash a sink of dishes) and when I looked for Calculator, it was reinstalled and would open. 🙂

  7. #4 – Had to create new user account, both with admin properties. My issue now is when I deleted the old user, the folder name remains in the users folder: C:\Users\. I tried deleting the folder but it stops, saying that folder is open. I had logout of it already.

  8. This is an addition to my comment of yesterday. Not only did method 2 fix my Calculator app not starting but it also fixed other apps/applications that had the same symptoms. Apps/applications like Office Word, Excel, Calendar were fixed. BIG thanks to all involved with that method.

  9. Method 2. Reinstalled Win 10 Calculator using Powershell. It seems to have worked.

  10. Or … stay with me here.

    Microsoft could fix their (widely known) buggy software.

    Crazy concept.

  11. thank you, method 2 reinstall from powershell worked a charm. unintall and reinstall through windows apps and features failed as did reset.
