Since Internet Explorer has now been deprecated, there is a need to import updates to WSUS natively without the installation of additional browsers. I’ve found that some of the functionality can be accomplished with Microsoft MVP Chrissy Lemaire’s “KBUpdate” PowerShell module, but it merely facilitated the process by downloading the update, and thus, I did…

PowerShell – Add/Modify Registry Key
Creating or modifying registry keys in PowerShell is a task that comes up frequently when working with Windows.

PowerShell- Clearing Nullified Environment Variables
I have posted before on the nuances of handling environment variables with PowerShell. I recently encountered an issue where I found a shortcoming of some of my previous scripting work. I was unable to clear nullified environment variables in my current session. I can’t take credit for the script I pieced together to accomplish this,…
