Function Get-Software {
<#
.Synopsis
Function to get the installed Software from a local or remote Windows System.
.DESCRIPTION
Function to get the installed Software from a local or remote Windows System.
This function offers Objects with informations similar to the Installed Software Window-view in the Windows Systemmanagemend.
This function will return information about each windows installer-based application out of the Registry 'Uninstall' key (32 and 64 Bit).
In order for a registry key to be opened remotely, both the server and client machines must be running the remote registry service, and have remote administration enabled.
If the remote registry service is not accessible then you can use this function with PowerShell remoting.
ADVICE: The WMI/CIM Win32_Product class is considered evil!
It is not recomende to use WMi/CIM and the class Win32_Product for this task!
Unfortunately, Win32_Product uses a provider DLL that validates the consistency of every installed MSI package on the computer.
If a Software installation is inconsistent the Sofware starts to try to repair themself with a reinstallation!
That makes it very, very slow and in case of a inconsistent Software the task will hang!
If you use the Computername Parameter of this Funktion please registry service of one Computer connect to (many) other Computers even If you use PowerShell Jobs with this Function.
This is very slow!
If you like to query many Computers use this Funktion with PowerShell remoting so that it is executed on the target systems!
See Invoke-Command Example in section Examples
.PARAMETER Computername
Specifies the target computer for the operation.
The local machine registry is opened if Computername is an empty String "".
Default is an empty String "".
.PARAMETER IncludeEmptyDisplaynames
Returns even Software Objects with empty Displaynames
Default is to NOT return Software Objects with empty Displaynames
.EXAMPLE
Get-Software
Retrieves the Installed Software from the locale System
.EXAMPLE
Get-Software -IncludeEmptyDisplaynames
Retrieves the Installed Software from the locale System include Software with empty displaynames
.EXAMPLE
Get-Software -ComputerName 'Server1'
Retrieves the Installed Software from the remote System 'Server1' out of the registry
In order for a registry key to be opened remotely, both the server and client machines must be running the remote registry service, and have remote administration enabled.
