If you want to create and run your own PowerShell scripts, you need to digitally sign your scripts.
To create your own so called "self-signed" certificate you'll need
makecert.exe that comes with the .NET Framework 2.0 SDK.
To learn more about signing your scripts, start a PowerShell shell, type
help about_signing and read this text carefully.
help Set-AuthenticodeSignature -detailed and read this text just as carefully.
You may want to redirect the text into two text files by using the following commands:
get-help about_signing > C:\about_signing.txt
get-help Set-AuthenticodeSignature -detailed > C:\Set-AuthenticodeSignature.txt
You can then keep and/or print the files C:\about_signing.txt and C:\Set-AuthenticodeSignature.txt for future reference.
After signing a script, and allowing scripts to run on your system, don't forget to start the command line with a dot to run the script (read the chapter on Parsing in the Getting Started Guide).
