Once in awhile, we get questions about the best practice for PowerShell’s execution policy when it is included as part of a standard desktop image.

This is one of the main reasons that PowerShell ships with a “Restricted” execution policy. Since you have to explicitly enable or install PowerShell, we’ve frequently been asked why we aren’t more permissive by default. After all, you did …

Last night, I flew my first half-hour as Pilot in Command of N8756C, a 1977 Piper Warrior. In flying, a pilot’s First Solo is a huge milestone. After hours of training and ground study, you finally take to the air on your own.

The most difficult part of flying is getting back down, so the First Solo is three takeoffs and landings – about half-an-hour in the traffic pattern. It seemed to be the flight that would …

One question that comes up fairly often when dealing with (or writing!) secure cmdlets is how to properly handle usernames and passwords. The solution there is to use (or make) the -Credential parameter of type PSCredential. A PSCredential object helps ensure that your password stays protected in memory, unlike cmdlets that accept a straight username / password combination.

If a parameter is of type PSCredential, …

After what seems like an eternity, I finally got to start my official flight training. As a Canadian (AKA “Alien,”) applying for flight school also means getting your fingerprints taken and being put in a special registration system. My training permission cleared late last week, so I booked my first lessons as soon as I could. In fact, for a government agency, the flight registration process was …

Once in awhile, you’ll see a PowerShell screenshot that is still black and boring like the traditional cmd.exe prompt. Other times, you’ll see the fancy blue window you’ve come to love. Why the difference? And if you’re suffering from black window syndrome, what can you do about it?

Before shipping Version 1, our marketing and design teams set to make the PowerShell window a unique and marquee …

If you’re testing your PowerShell scripts (manually or automatically,) one of the first questions you’ll end up asking yourself is, “did I test enough?”

This is common problem in all of software development. To the rescue is a simple metric known as “Code Coverage” – a measure of how much code you exercised during the testing of that code.

However, the measurement is just the end …

For a long time, I’ve been thinking about learning to fly. One of the random long-distance-drive conversations I like to have is, “What job would you do if you were for some reason prevented from doing what you do now?” For me, flying has always been something I would entertain, but only romantically. The downsides to doing it professionally are huge – the time away from your family and strict …

A few years ago, we experimented with a “Live” version of Get-ChildItem that retrieved elegant textual context-based advertisements from the internet as you used PowerShell.

This has been very successful, but unfortunately, a small subset of our trial user population has experienced crashing behaviour due to these new shell modifications. We have been unable to reproduce the issue in our labs, so the users …

BgShell is a proof of concept PowerShell host that explores the idea of “PowerShell Everywhere.”

What if PowerShell was always at your fingertips – making quick calculations easier than launching Windows Calculator? Or, making a “quick ipconfig” with PowerShell just a keystroke away? BgShell offers PowerShell Everywhere, and instant gratification. Simply press Control-Alt-B, and the …

In our most recent CTP, we exposed PowerShell’s parsing and tokenizing API for the great benefit of ISVs and hobbyists alike. As an initial demonstration of it, Show-ColorizedContent let you display nicely formatted code listing in your console:

While this is very cool, we can actually push the parsing and tokenizing API even …
