Windows 10 Store Apps Missing

Purpose:
This post explains how to reinstall the Windows 10 Calculator app after it has been uninstalled

Symptom:
Windows 10 Calculator App missing

Resolution:

Issues reinstalling Win10 Store apps after removing them. This is specific to the Windows Calculator app.

Requirement is to have Base Filtering Engine and Windows Firewall service turned on.
*Note* - This is also a requirement for Windows 10 Updates to function correctly.

If the folders in the C:\Program Files\WindowsApps directory have been deleted or are missing find another machine that does have these folders and copy them into your machines directory. I also had to copy the VCLibs directories (highlighted below - You'll see why in a minute why these are needed.)



After you have these directories open up an elevated powershell window and register the apps using this command (specific to Calculator)

Add-AppxPackage -Register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1703.601.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode




However when I ran this command I got an error about the VCLibs missing. So  I registered these VCLibs first with these command:

Add-AppxPackage -Register "C:\Program Files\WindowsApps\Microsoft.VCLibs.140.00_14.0.24123.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode

Add-AppxPackage -Register "C:\Program Files\WindowsApps\Microsoft.VCLibs.140.00_14.0.24123.0_x86__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode



And then re-ran the command to register the Calculator app.

Add-AppxPackage -Register "C:\Program Files\WindowsApps\Microsoft.WindowsCalculator_10.1703.601.0_x64__8wekyb3d8bbwe\AppxManifest.xml" -DisableDevelopmentMode

Cause:
