Google is the most underestimated resource EVER.
Look for your question on it before you start asking people.
If you have a problem, chances are other people will have had the same/similar question waaaaaaay before you and chances are this question has already been answered.
Personally the biggest recommendation I can give concerning learning PowerShell is to read the following 2 books:
While there are various other books also freely available, if you’re really serious about getting into PowerShell, these books will help you a LOT!
The former will teach you all about PowerShell as a language, the most important Cmdlets, how to read Help etc etc.
Once you’ve completed the first book, you can move on to the latter, to hone your skills and create re-usable tools!
Other freely available books that might interest you:
A must watch is the freely available course by PowerShell’s creator/founder, Jeffery Snover
And be sure to check other options available on MVA, the list keeps growing
Jeffery Hicks’ YouTube channel
Don Jones’ YouTube channel
PluralSight courses [they might not be free, but damn are they good!! At least try the free trial account to give it your own judgement]
Another very underestimated source of knowledge is the people around you.
See if there’s a PowerShell User Group in your area.
If you’re in The Netherlands, you can check the Dutch PowerShell User Group here or otherwise perhaps check the listing here to find a group near you.
Power comes in numbers, just as PowerShell is built to serve 1 machine or 100.000 with the same effort.
Forums and Social Media bring you a whole source of information within your grasp.
Some of the added links are also household favorites for people interested in PowerShell.
