Active Directory DHCP Report to HTML or EMAIL with zero HTML knowledge

I'm pretty addicted to reading blog posts. I saw this new blog post the other day, where the author created the DHCP HTML report, and he did it by manually build headers, footers, table borders, and finally, some adding some coloring to the percentage of DHCP being in use. It's the "standard" approach to build HTML in PowerShell, and I've seen a similar path before, but that got me thinking how much time it would take for me to replicate the very same functionality using PSWriteHTML module.

Using Win32_UserAccount WMI filter in PowerShell/Group Policies and what to avoid

Some months ago, I created PowerShell Script to create local administrative users on workstations - Create a local user or administrator account in Windows using PowerShell. It's a bit overcomplicated, but the goal was it should work for Windows 7 and up, and that means supporting PowerShell 2.0. As part of that exercise, I've been using Win32_UserAccount WMI based query to find local users and manage them to an extent. While Get-LocalUser exists, it's not suitable for the PowerShell 2.0 scenario. I also use the same query in GPO for WMI filtering. You can say it's been a good friend of mine.

Converting Pester V4 to Pester V5 basics

Now that Pester V5 is out, I decided that I need to make sure that my Pester tests for all my modules keep on running correctly. Some substantial changes in Pester add new features, changing some things, but that also means all the tests that you have defined most likely will need a small push to get it up and running again on Pester V5. Starting this blog post, I wanted to mention that I am by no means an expert on Pester, but I do use it for some time now for most of my projects.  I am using basic functionality, but even that basic functionality stops working once you upgrade from PesterV4 to PesterV5, so I thought I would save you some time and give you a small overview of how you can quickly fix it. It works for me, but you may have to find your way to fix things.

Get-ADObject : The server has returned the following error: invalid enumeration context.

In the last weeks, I'm working on a PowerShell module that the main goal is to work on gathering and fixing GPOs. I've been testing my module a lot of times on my test environment, and it worked fine till the moment I run it on production, and it started to fail pretty quickly. The difference between my environment and production is 25 GPOs vs. 5000 GPOs. The error I was getting:

Getting Verified badge next to your GitHub commits in VS Code

A bit over two years ago, I started posting my PowerShell code as modules on GitHub. Initially, I planned to have them hosted on my website, but few people asked to post it there, and they were right. It would be fairly hard for me to keep my code up to date on my website and, at the same time, let people submit bug reports or help with some PR. It was the right decision! Now that I've worked for over two years on GitHub as a daily driver, I wanted to get a new green badge that's shown on GitHub when you edit some code. I don't know if you ever noticed, but if you write any code, text file directly via the GitHub.com webpage, your commits always have Verified badge next to them.

Office 365 – Limiting license to minimum apps required

Office 365 has a lot of options and applications to choose from. Enabling one E1, E3, or any other license gives the user a lot of features, including Exchange, SharePoint, and Teams. But what if you want to make sure that the user can access only Microsoft Teams? By default, you can do it manually during the assignment of the license. Simply choose only Apps you want to assign to a user.
