Feex tok say

If person type calc and I see both calc.exe and CalculatorApp, I dey leave di Store app make e be di window. I no dey hunt mspaint for calculator.

## Wetin be calc.exe?

calc.exe dey launch Calculator. E no be mspaint.exe. For current Windows, di app wey dey show face na often CalculatorApp.exe under WindowsApps.

## Wetin e dey do?

E dey resolve di Calculator app execution alias and start di Store app. E no dey edit bitmaps and e no dey host di full Calculator UI alone.

## Wetin make am dey run?

Na you run calc, Win+R calc, or shortcut wey still carry di name Calculator. Di shim fit close after CalculatorApp.exe don show.

## Inspect the running instance

Inside Windows PowerShell, this read-only query show matching process IDs, creation times and executable paths on this PC. (pcm)

`Get-CimInstance -ClassName Win32_Process | Where-Object { $_.Name -eq 'calc.exe' } | Select-Object ProcessId, ParentProcessId, CreationDate, Name, ExecutablePath | Format-List`

No result or a path we no fit access is inconclusive. Protected processes fit restrict access, and process IDs fit be reused. Keep personal paths local. (pcm)

Use the [file-identity guide](https://feex.it/wiki/l/pcm/software/system/verify-executable-path-signature/) to compare signatures and product metadata. A filename alone no fit establish safety. (pcm)

## E dey safe?

Check dis running file

System32 calc.exe na di Microsoft shim. Any calc.exe wey dey beside crack no be Calculator.

Compare the recorded location with the actual file. A familiar folder alone no fit establish identity. (pcm)

`C:\Windows\System32\calc.exe`

- Launch shim for current Windows
- UI na often CalculatorApp.exe
- No be mspaint.exe

## I fit end am?

Usually e don hand over work already

If you end calc.exe after di window don open, e fit no do anything. End CalculatorApp.exe if na Calculator you wan close.

## I fit comot am?

No

No delete calc.exe. Uninstall Calculator from Apps if you want make di Store app commot. Di shim na still system alias.

## E suppose start with Windows?

On demand. Startup calc na shortcut wey you add by yourself.
