Symptoms
Consider the following scenario:
-
You have some custom PowerShell scripts or modules that contain a reference to the built-in $MyInvocation instance.
-
You execute the scripts or modules on a Windows 8-based or Windows Server 2012-based computer by using Windows PowerShell 3.0.
-
Some objects are passed through a pipe.
In this scenario, the value of the $MyInvocation.MyCommand object is set to null.
For example, the issue occurs when you run the following script:$Line= Get-Content $file
$Line | foreach-Object { write-host "** MYCOMMAND [2] IS NULL?: " ($MyInvocation.MyCommand -eq $null) " --->" $_ }
Note This issue does not occur when you run the script by using Windows PowerShell 2.0.

The dates and the times for these files are listed in Coordinated Universal Time (UTC). The dates and the times for these files on your local computer are displayed in your local time together with your current daylight saving time (DST) bias. Additionally, the dates and the times may change when you perform certain operations on the files.
Windows 8 and Windows Server 2012 file information notesImportant Windows 8 hotfixes and Windows Server 2012 hotfixes are included in the same packages. However, only "Windows 8" is listed on the Hotfix Request page. To request the hotfix package that applies to one or both operating systems, select the hotfix that is listed under "Windows 8" on the page. Always refer to the "Applies To" section in articles to determine the actual operating system that each hotfix applies to.
-
The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:
Version
Product
Milestone
Service branch
6.2.920 0.16 xxx
Windows 8 and Windows Server 2012
RTM
GDR
6.2.920 0.20 xxx
