Windows PowerShell command line shell execution policies

Microsoft Windows PowerShell command line shell and scripting language helps IT professionals achieve greater control and productivity. Using a new admin-focused scripting language, more than 130 standard command line tools, and consistent syntax and utilities, Windows PowerShell allows IT professionals to more easily control system administration and accelerate automation.

Windows Powershell supports the following execution policies:

Restricted

  • Default execution policy.
  • Permits individual commands, but scripts cannot run.

AllSigned

  • Scripts can run.
  • Requires a digital signature from a trusted publisher on all scripts and configuration files, including scripts that you write on the local computer.
  • Prompts you before running scripts from trusted publishers.
  • Risks running signed, but malicious, scripts.

RemoteSigned

  • Scripts can run.
  • Requires a digital signature from a trusted publisher on scripts and configuration files that are downloaded from the Internet (including e-mail and instant messaging programs).
  • Does not require digital signatures on scripts run from the local computer.
  • Does not prompt you before running scripts from trusted publishers.
  • Risks running signed, but malicious, scripts.

Unrestricted

  • Unsigned scripts can run.
  • Scripts and configuration files that are downloaded from the Internet (including Microsoft Outlook, Outlook Express and Windows Messenger) run after warning you that the file originated from the Internet.
  • Risks running malicious scripts.
