Powershell' is not recognized as an internal or external command, operable program or batch file

Sounds like you're missing an environment variable.

Add this to your Path environment variable:

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

OR

Change your script to this:

%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\powershell.exe -Command "your command"

Remove BOM byte from the beginning of batch file or convert it's encoding to ANSI. BOM treats system to think you use unavailable command.

You only need to add it to your environment variables, just follow the following two simple steps:

1.write env in the search bar

or Right click start button -> System -> Advanced system settings -> Environment Variables... -> Select PATH

2. click on the new button and add the following path:

C:\WINDOWS\System32\WindowsPowerShell\v1.0\

or %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\
