Testing for the Presence of a Registry Key and Value


There are a number of different ways to test for the presence of a registry key and value in PowerShell. Here’s how I like to go about it. We’ll use an example key HKLM:\SOFTWARE\TestSoftware with a single value Version:

Reporting On Installed Windows Programs Via The Registry


Quite a common request for working with Windows machines is to report the software installed on them. If you don’t have a centralised system for reporting on client software (many places don’t) then you may turn to some form of scripted method to obtain this information.

Most people tend to head to Add / Remove Programs when thinking about what software is installed in Windows. However, not all applications will always populate information in there, depending on how they have been installed. Additionally, to query that information you would typically query the WMI class Win32_Product, however this can lead to performance issues.

[UPDATED] PowerShell Summit 2013 Conference Schedule


If you are attending the PowerShell Summit next week in Redmond, you might want to make sure you have copies of the schedule on hand.  There are two tracks, and I have created two pdf documents, one for each track, that provide the full schedule including session abstracts and speaker bios.

PowerShell Summit 2013 Conference Schedule – Track 1

PowerShell Summit 2013 Conference Schedule – Track 2

While those details are very useful, some of the conference attendees have expressed an interest in having a consolidated view of the agenda so that they could see which sessions were taking place on each of the tracks and choose which they were more interested in.  Ask, and ye shall receive.  Here is a consolidated view of the conference sessions on all tracks, with each day on a separate page.

PowerShell Summit 2013 Conference Schedule – At at glance

Note that if you don’t have a ticket for the conference, it is sold out for this year.  We’re planning the 2014 conference now, so keep watching this blog for news about that conference as it becomes available.  There are already a few posts about it that are worth reviewing if you missed them.

Thanks, and enjoy the conference next week!

Kirk out.

Up Next: Edward Haletky Talks About VMware


Texiwill

One of our favorite topics here at the PowerScripting Podcast is managing VMware products with PowerShell. This week, we’re tapping a new resource on the topic who has a very different background than Hal and Jon (HE LIKES LINUX) which should make for some interesting conversation. We hope you can make the show this Thursday July 16th @ 9pm EDT, broadcast live on Ustream, or available for download in all the usual ways just a few days later.

Here is a little bit about Edward (aka Texiwill on VMware Communities & Twitter):

Edward L. Haletky is the author of VMware vSphere(TM) and Virtual Infrastructure Security: Securing the Virtual Environment as well as VMWare ESX Server in the Enterprise: Planning and Securing Virtualization Servers. Edward owns AstroArch Consulting, Inc., providing virtualization, security, network consulting and development.
