PowerShell

About

This project offers a few useful powershell scripts. I am trying to sort them as good as possible and document them in this and other .md files.

Content

autoinst

This folder contains automated installation scripts for tools I currently use.

Some tools require 7z.exe to be avaialable for performat Zip extraction. It is recommended to install "PeaZip" first to make this available.

tools

This folder contains PowerShell tools and scripts used for various purposes. Each script is documented by using a README.md file in each folder.

Specials

The installer calls shown in this section will ...

• Download the corresponding script into a temporary directory.
• Unblock the file as it is downloaded from the internet.
• Save the current execution policy.
• Set the execution policy to Unrestricted.
• Call the script.
• Restore the execution policy to the saved state.
• Remove the temporary directory.
