Posted by: | November 20, 2015 Comments Off on Creating Registry Key |

I had a question left on the blog asking how to create a registry key. My preferred method is to use the CIM class = StdRegProv.

Splatting and Default parameters

Posted by: | November 19, 2015 Comments Off on Splatting and Default parameters |

One thing you don’t hear much about is default parameters. Consider this Get-CimInstance -ClassName Win32_LogicalDisk -Filter "DeviceId = ‘C:’"   A pretty standard use of CIM.   Now think if you have to do this across a number of machines on a regular basis.  Typing could get a bit tedious. You could use splatting: $params […]

Out of Process

Posted by: | November 18, 2015 Comments Off on Out of Process |

One thing I’ve been seeing come up a lot recently is the problem of modules and cmdlets cot being available when jobs and workflows are executed even though the module has been specifically loaded into PowerShell.   This is because workflows and Jobs run in a separate process when you execute them – NOT your […]

WMI wildcards and filtering

Posted by: | November 11, 2015 Comments Off on WMI wildcards and filtering |

A question on the forum asking about filtering WMI results raises a number of interesting points.   The user wanted to pass a computername and a filter term to pull product information from remote machines. I ended up with this $computername = $env:COMPUTERNAME $filter = ‘Live’ $scriptblock = {     param($filter)     Get-WmiObject -Class Win32_product […]
