Video: Richard Siddaway – WMI: Gems and Gotchas

Another great recording from US TEC 2011 PowerShell Deep Dive – Richard’s session on WMI in PowerShell. Richard has written an entire book on that topic so he is probably one of the best experts in the area.

Abstract: “WMI has been part of the Windows environment for a long time, and has a reputation for being very powerful but very difficult. PowerShell has made WMI easier to use, but the interaction between the two is still relatively undocumented. PowerShell has also opened WMI up in a number of ways but introduces a number of “gotchas” in the process. This US Experts Conference 2011 PowerShell Deep Dive session demonstrates that that any “gotchas” can be overvcome and WMI offers a treasure trove of functionality to the administrator. The video also answers a number of key questions about WMI and PowerShell, including:

• Is Invoke-WmiMethod always the answer?
• How can I change WMI information?
• How does WMI authentication and authorisation work?
• Should I use explicit remoting, implicit remoting or WMI?
• WMI overlaps with some cmdlets e.g. Get-Process and Win32_Process — which should I use when?
• How do I get the best of WQL? Do I use queries or filters?”
