Expected behavior:
the typescript command isn't running at all due that tsc.ps1 isn't digitally signed, my pc execution policy

PS C:\Users\xxx> Get-ExecutionPolicy
AllSigned

Actual behavior:

PS C:\Users\xxx> tsc
tsc : File C:\Users\xxx\AppData\Roaming\npm\tsc.ps1 cannot be loaded. The file
C:\Users\xxx\AppData\Roaming\npm\tsc.ps1 is not digitally signed. You cannot run this script on the current system.

not related directly to ts , it's powershell script not signed issue

Edit , I know this isuue could be worked around by running following command in powershell

PS> Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine

am not security expert but assuming that the user don't have to change their pc execution policy in order to run typescript

I think that tsc.ps1 is created by npm.

just type tsc.cmd the ts filename

[sinaAtabaki]

or just delete
C:\Users%USERNAME%\AppData\Roaming\npm\tsc.ps1
Now it will automatically load tsc.cmd when you type tsc in the command prompt/ powershell
