Useful PowerShell Blogs
This is a sampling of some of the blogs that are being written on the subject of Windows PowerShell. Some of these are independent blogs and their contents are not reviewed or controlled by Microsoft.
PowerShell Scripts
This section represents links to actual PowerShell scripts that have been developed for review and reuse. These scripts are intended to keep administrators from having to "start from scratch" when developing scripts. While they will almost certainly require some modification, the intent is to give admins a starting point to learn how to do various tasks related to PowerShell in their own environments.
WARNING: YOU SHOULD NEVER RUN A SCRIPT IN PRODUCTION IF YOU AREN'T 100% CERTAIN OF WHAT IT WILL DO. ALL SCRIPTS SHOULD BE THOROUGHLY UNDERSTOOD AND TESTED IN A NON-PRODUCTION ENVIRONMENT PRIOR TO BEING USED IN PRODUCTION. THIS HELPS ENSURE THAT PRODUCTION PROBLEMS DO NOT OCCUR AS A RESULT OF RUNNING SCRIPTS THAT HAVE NOT BEEN TESTED AND VALIDATED BEFOREHAND.
