It comes as a shock to realize that by default, and by design, PowerShell code just won't
execute because of security concerns. Fortunately you can change
this behavior easily with
Set-ExecutionPolicy.
In the case of Windows 7 and Server
2008, you don't need to download any extra files, just 'Add Feature' Windows PowerShell.
However, for older operating systems, installing can be confusing because
there are different versions of PowerShell for XP, Windows Server 2003 and
Vista. For such legacy systems only, you need to
download PowerShell from Microsoft's site.
Once you have installed PowerShell 2.0, I recommend choosing the
ISE (Integrated Scripting Engine) version, it
will save you buying a text editor.
I like experiments. Get-Execution allows us to take a snapshot
before we make any changes with 'Set'. My other reason for
introducing 'Get' is to help with troubleshooting why scripts are or
are not working.
Not only is this a job that needs doing so that all your other PowerShell
scripts work, but also changing the script execution behaviour gives you
valuable experience with the 'Set' verb.

below, you may wish to append this line: Get-ExecutionPolicy

Recommends: Permissions Analyzer - Free Active Directory Tool
I like the
Permissions Monitor because it enables me to see quickly WHO has permissions
to do WHAT. When you launch this tool it analyzes a users effective NTFS
permissions for a specific file or folder, takes into account network share
access, then displays the results in a nifty desktop dashboard!
Think of all the frustration that this free utility saves when you are
troubleshooting authorization problems for users access to a resource.
Checking the help file may reveal useful parameters, for instance -list
may help with troubleshooting, see more below.
Troubleshooting Set-ExecutionPolicy
While you do all of the above and configure Set-ExecutionPolicy scripts
may still not run because of Group Policy restrictions. Here are
the factors to consider:
Computer Group Policy > User Group Policy
> Process (session) execution policy > User execution policy > Computer
execution policy.
# PowerShell Set-ExecutionPolicy List Clear-Host
Get-Help Set-ExecutionPolicy -list
Having to adjust Get-ExecutionPolicy is the price we pay for security,
administrator must be allowed to turn off PowerShell code to stop
hackers or their viruses gaining control.
Set-ExecutionPolicy tackles the specific problem that your PowerShell script
will not run.
Fortunately if you don't like this behavior you can change it easily with
Set-ExecutionPolicy.

Windows Management Instrumentation (WMI) is one of the hidden
treasures of Microsoft operating systems.
Fortunately, Solarwinds
have created the
Free WMI Monitor so that you can actually see and understand these gems of
performance information. Take the guess work out of which
WMI counters to use for applications like Microsoft Active Directory,
SQL or Exchange Server.
