PowerShell: Update-Help via Scheduled Task in Group Policy Preferences


If you’re like me, you probably like to ensure that all your computers have PowerShell updatable help updated on a regular basis. You can achieve this using a variety of methods, but since Group Policy Preferences are available out of the box using Windows 7 and later, I figured it would be the perfect tool to keep PowerShell help up-to-date! The following guide will show you how to implement a Windows Scheduled Task to update PowerShell version 3.0 help on a regular basis.

The following operating systems include Group Policy Preferences Client Side Extensions (GPP-CSE) out of the box:

  • Windows 7
  • Windows 8
  • Windows Server 2008 R2
  • Windows Server 2012

You can also deploy the Windows Management Framework Core 3.0, and Group Policy Preferences Client Side Extensions to Windows Server 2008 non-R2 systems, however the equivalent client operating system, Windows Vista, does not support WMF 3.0.

ConfigMgr 2012: Ccmeval.exe causing client corruption

I’ve discovered, on more than one occasion, that the ConfigMgr 2012 client’s ccmeval.exe, which is intended to resolve client health related issues, actually breaks the ConfigMgr client. This has happened on a Windows 8 RTM client, and I’m fairly certain that it affects Windows Server 2012 as well. You might be aware that Windows 8 and Windows Server 2012 are unsupported client operating systems with ConfigMgr 2012 RTM, but will be officially supported in Configuration Manager 2012 Service Pack 1 (SP1).


By default, when the ConfigMgr 2012 client is installed, a Scheduled Task is registered under the \Microsoft\Configuration Manager called “Configuration Manager Health Evaluation.” The command line that is called is simply ccmeval.exe, with no command line arguments. The task will run approximately around midnight (12:19 AM on my test client) every night.

Installing VMware Workstation 9.0 on Windows 8 RTM

I recently ran into an issue where VMware Workstation 9.0.1 refused to install, with the management port configured to the default of port 443. It was complaining that another process was using that port already. I broke out [cci]netstat -aon[/cci] and discovered that wwahost.exe was listening on port 443. It turns out that [cci]wwahost.exe[/cci] is … Read more Installing VMware Workstation 9.0 on Windows 8 RTM

PowerShell: Embed binary data in your script

When writing automation scripts or modules, you might find that you frequently reference external binary data.

Binary data? Well, that accounts for all data!” you might say.

Yes, that’s true. But I’m talking about binary data as opposed to files containing simple ASCII or UTF-8 data. Maybe there’s some better terminology to describe that, but hey it works for now. Binary data could include things such as:

  • Word documents
  • Executable (Portable Executable format)
  • Code libraries (DLLs)
  • Registry files
  • etc.

In the case of executables, oftentimes they provide useful functionality that would take many lines of PowerShell code to replicate. Some developers, for better or for worse, elect to use these utilities instead of going through the effort of writing the necessary code to handle the function natively in PowerShell. This creates an additional dependency when porting the PowerShell code, as the author must be sure to include the utility with their code, or otherwise ensure (via documentation, for example) that the target user will already have it available.

Wouldn’t it be nice if you didn’t have to depend on the user having some executable pre-installed, just to get your script to work, though? Unfortunately the little topic of “software licensing” can sometimes prevent redistribution of software that you are not given explicit permission to copy, however there are also many cases where this is allowed (eg. open-source projects). The work-around in cases where redistribution is not allowed, is to either direct the user where to download the software from, or automate it for them.
