PowerShell: List Strongly Typed Names in Global Assembly Cache

I dislike using deprecated commands or APIs when I know that there’s a more modern method of performing an action. I also generally prefer to use Windows PowerShell as a .NET scripting language, rather than constantly relying on cmdlets. To be sure, I use a balance of both concepts, since cmdlets can save a whole lot of coding a lot of the time.

Every time I want to load an assembly into PowerShell, the first thing that pops into my mind is using the LoadWithPartialName() method:

1
[Reflection.Assembly]::LoadWithPartialName();

Unfortunately Microsoft recommends against using that static method, as it is deprecated, and recommends use of other methods such as LoadFile() or Load() like:

1
[Reflection.Assembly]::Load(StronglyTypedAssemblyName);

In the interest of not breaking my conscience, I would like to use this method, but the problem then becomes that I have to constantly figure out what the strongly-typed name of the assembly I want is. To help solve this problem, I decided to write a PowerShell script that extracts information from the .NET assemblies in the Global Assembly Cache (GAC), since those are generally the most common ones I’ll need to reference.

Checking Status of a Windows 7 System Image

If you’re running Windows 7, you may periodically create a “System Image” which is essentially just a VHD backup of your system. When you invoke the task, you will be presented with a dialog box similar to the following, which shows the progress of the backup:

image

If you are scripting something, and want your script to proceed when the backup has completed, you can run this command line:

wbadmin.exe get status

This program will "block" (continue running) and report progress, as a percentage, until the backup has completed.

HP ProLiant DL360 G7 Video Driver

I was looking for a video driver for the HP ProLiant DL360 G7 so I could import it into ConfigMgr for the purposes of deploying Windows Server 2008 R2 to them. Oddly enough, HP doesn’t list a video driver available for download on the driver download page for this system model. On one server, I noticed that the device name was "ATI ES1000,” and most of you are probably aware that the ATI brand name has been gone for some time, so this seemed a bit odd.

PowerShell: Override GPO and Detect Windows Updates

Introduction

If you’re using a workstation in an enterprise environment, there may be Active Directory Group Policy Object (GPO) settings forcing a certain behavior of the Microsoft Windows Update Agent (aka. Automatic Update Agent). You might be a power user who wants to actually ensure that their workstation is fully patched before the IT department releases patches according to their standard cycle. One option would be to ask your IT department to include you in the pilot group for software updates, but failing that option, you can temporarily override the GPO settings and force an updates detection.

PowerShell: Get a List of Installed Software from ConfigMgr

Let’s say you’ve got Microsoft’s System Center Configuration Manager (SCCM / ConfigMgr) in your IT environment (and if you don’t, why on earth not!). If you’re on the desktop management team, you might occasionally get requests from someone on a network or security team, inquiring as to the installed software on a particular client, or group of clients.

Rather than diving straight into the ConfigMgr reports, as most people do, sometimes it’s just faster to load a data set into PowerShell and massage the data from there. Why PowerShell? Well, it provides very easy, real-time filtering and sorting capabilities, and if you need to make a modification to a temporary “report,” you don’t have to worry about modifying the Report object in the ConfigMgr provider, which is typically done through the ConfigMgr console.
