And yes, that's "free as in beer," not "free as in what some people think all information wants to be."[1]
Frank Koch and Marcel Trümpy of Microsoft (in Switzerland) have created not one, but two Windows PowerShell ebooks, and you can get them both for free:
- A Windows PowerShell course book with associated demo files and examples.
- A Windows PowerShell server administration book with associated demo files and examples.
Get them both in one easy download either in English or German. The downloads are from Microsoft and no registration is required, according to the blog posting.
[1] If you believe all information wants to be free, I challenge you to put your money where your mouth is and post your Social Security number (if you live in the USA; equivalent if you don't), birthdate, address, personal phone number, and bank account information here in my comments. After all, that's all information -- and it wants to be free!
