While working on a task scheduling a powershell script, it was noticed that the powershell command does not execute from the command prompt on a server. When run I would encounter the following error: ‘powersehll’ is not recognized as an internal or external command, operable program or batch file.

After searching around Google / Bing I gave up and made the following attempt which worked out for myself and the system owners.

Looking at the system PATH variable seems correct with the expected path variable included under system variables: %SYSTEMROOT%\System32\WindowsPowerShell\v1.0\

I decided to check with my user only: I added ‘%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\’ to my user variable with success

In the systems path variables and removed the reference and added it to the end of the line which was successful in resolving the system wide issue.

Cause of issue is still unknown.  Perhaps an ordering issues in the variables.  If you know please feel free to comment.
