I uninstalled the Calculator app like this in PowerShell:

Get-AppxPackage *windowscalculator* | Remove-AppxPackage

This one worked for me, just combined the commands from the other answers found here. Note: you have to use the -Allusers option with the Get-AppxPackage command since it is not installed anymore under your current user account:

Get-AppxPackage -allusers *windowscalculator* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

Here is the MS Store link to the Windows Calculator.

Note: This will only work if you have the Windows Store app installed.

To reinstall an individual app use PowerShell and run it in admin mode. Screenshots:

Next get the full name of all apps, e.g. Windows Calculator paste this snippet in PowerShell and hit enter:

get-appxpackage -allusers | Select Name, PackageFullName

For single full name of the desired app name, e.g. Windows Calculator paste this snippet in PowerShell and hit enter:

Get-AppxPackage *windowscalculator*

Now copy the full name that looks like this: Microsoft.WindowsCalculator_10.1601.49020.0_x64__8wekyb3d8bbwe

Finally the we are going to install that app again with this snippet:

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsAlarms_10.1603.12020.0_ x64__8wekyb3d8bbwe\appxmanifest.xml" -DisableDevelopmentMode

Re-installed app is available without restart of the PC!

N.b: To remove individual apps use this code:Get-AppxPackage *alarms* | Remove-AppxPackage

A list of all apps when removing is (Here)

Try Get-AppxPackage *windowscalculator* | Add-AppxPackage

or the following to install all default apps:Get-AppxPackage -AllUsers| Foreach {Add-AppxPackage -DisableDevelopmentMode -Register “$($_.InstallLocation)\AppXManifest.xml”}

I had the same issue where I installed a stripped version of Windows 10 (for performance gains and lower latency) and the Calculator was missing.

I managed to find the old Windows 7 calculator and install it easily. Just google "old calculator for windows 10" and the first link should be from winaero website.

Add-AppxPackage -register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1906.53.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode

Just install it from the Windows Store if you have that installed. Windows Calculator |

Just as an FYI, the other answers above work, BUT if you're on an AD domain and a VPN, going to Microsoft Store may not work because you could be blocked. Try the command line if the store blocks you.
