        Process to Repair or Reinstall a Corrupted Calculator Installation

        If the Calculator app launches erratically or crashes, the installation may be corrupted. Below are steps to restore functionality, including system file checks and manual re-registration.
        • Run System File Checker (SFC)
          Corrupted system files can prevent `calc.exe` from executing. Use the built-in `sfc /scannow` tool to repair them:
          Steps:
          1. Open Command Prompt as Administrator.
          2. Execute:
          `sfc /scannow`
          3. Wait for completion (may take 15+ minutes). Restart if prompted.
          4. Verify the Calculator by launching it from Start Menu or via `Win + R` > `calc`.
          Note: If SFC reports errors but fails to fix them, proceed to DISM (Deployment Image Servicing and Management):
          `DISM /Online /Cleanup-Image /RestoreHealth`
        • Re-register the Calculator App
          Windows apps rely on registry entries for proper execution. Re-registering the Calculator can resolve missing or broken dependencies:
          Steps:
          1. Open PowerShell as Administrator.
          2. Run the following commands sequentially:
          `Get-AppXPackage WindowsCalculator -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}`
          `Get-AppXPackage WindowsCalculator -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -ForceApplicationRepair "$($_.InstallLocation)\AppXManifest.xml"}`
          3. Restart the system and test the Calculator.
        • Manual Reinstallation via Windows Features
          For classic `calc.exe` (non-UWP), reinstall via Windows Features:
          Steps:
          1. Press `Win + R`, type `optionalfeatures`, and hit Enter.
          2. Under Legacy Components, check Windows Calculator (if available).
          3. Click OK and restart.
          Note: This method is limited to Windows 10/11 Pro/Enterprise editions.
        • Clean Boot to Isolate Conflicts
          Third-party services (e.g., startup apps) may interfere with Calculator execution. Perform a clean boot:
          Steps:
          1. Press `Win + R`, type `msconfig`, and hit Enter.
          2. Go to the Services tab, check Hide all Microsoft services, then click Disable all.
          3. Go to the Startup tab and click Open Task Manager, then disable all startup items.
          4. Restart and test the Calculator. If it works, re-enable services/startup items one by one to identify the culprit.
