Execute ps1 files at command line

1. Open regedit.exe

2. Export copy of the registry

3. Navigate to

HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell

4.  Change the default from 'Open' to '0'

5. Could change default parameters to powershell.exe in HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\0\Command


Another option:
3. Navigate in registry to HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\Shell\Open\Command\

4. Change Old Value:
"C:\Windows\System32\notepad.exe" "%1"

to New Value:
"C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" -NoLogo -NoProfile -NonInteractive -ExecutionPolicy "Bypass" -File "%1"


Why not do this:

This makes it easy for dangerous .ps1 files to be executed.  With great power comes great responsibility.
