      [-Name] <String[]>
      [-Force]
      [-WhatIf]
      [-Confirm]
      [<CommonParameters>]

Description

The Remove-Module cmdlet removes the members of a module, such as cmdlets and functions, from the current session.

If the module includes an assembly (.dll), all members that are implemented by the assembly are removed, but the assembly is not unloaded.

This cmdlet does not uninstall the module or delete it from the computer. It affects only the current PowerShell session.

Examples

Example 1: Remove a module

Remove-Module -Name "BitsTransfer"

This command removes the BitsTransfer module from the current session.

Example 2: Remove all modules

Get-Module | Remove-Module

This command removes all modules from the current session.

Example 3: Remove modules by using the pipeline

"FileTransfer", "PSDiagnostics" | Remove-Module -Verbose

r.Management.dll')".

VERBOSE: Removing imported function 'Disable-WSManTrace'.
VERBOSE: Removing imported function 'Enable-PSWSManCombinedTrace'.
VERBOSE: Removing imported function 'Disable-PSWSManCombinedTrace'.
VERBOSE: Removing imported function 'Set-LogProperties'.
VERBOSE: Removing imported function 'Get-LogProperties'.
VERBOSE: Removing imported function 'Enable-PSTrace'.
VERBOSE: Removing imported function 'Disable-PSTrace'.
VERBOSE: Performing operation "Remove-Module" on Target "PSDiagnostics (Path: 'C:\Windows\system32\WindowsPowerShell\v1.0\Modules\psdiagnostics\PSDiagnostics.psm1')".

This command removes the BitsTransfer and PSDiagnostics modules from the current session.

The command uses a pipeline operator (|) to send the module names to Remove-Module. It uses the Verbose common parameter to get detailed information about the members that are removed.

The Verbose messages show the items that are removed. The messages differ because the BitsTransfer module includes an assembly that implements its cmdlets and a nested module with its own assembly. The PSDiagnostics module includes a module script file (.psm1) that exports functions.

Example 4: Remove a module by using ModuleInfo

$a = Get-Module BitsTransfer
Remove-Module -ModuleInfo $a

This command uses the ModuleInfo parameter to remove the BitsTransfer module.
