Windows users can reinstall Calculator and Microsoft Store

Users of Windows 10 and Windows 11 can resolve issues with the Windows Calculator and the Microsoft Store through several reinstallation and repair methods.

To reinstall the Windows Calculator, users can utilize the Microsoft Store by searching for the app and selecting ‘Get’ or ‘Install’. If the app is present but malfunctioning, repair or reset options should be attempted first. Alternative technical methods include using PowerShell or the winget command-line tool, as well as performing system file and image repairs.

For issues involving the Microsoft Store itself—such as crashes, freezing, or the app disappearing—reinstallation via PowerShell is a primary solution. This involves running a specific command in an administrator PowerShell window to re-register the package for all users. Other troubleshooting steps include clearing the cache or resetting the app to address error codes and update failures.
