If I open a new Powershell 7 session and run get-command Get-Website
the response I get is
Get-Command: The term 'Get-Website' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
If I then run import-Module WebAdministration and again run get-command Get-Website, this time I get the expectefd output of
CommandType Name Version Source
----------- ---- ------- ------
Function Get-Website 1.0 WebAdministration
If I close the Powershell 7 session, open a new one and run get-command Get-Website, the new session does not recognise the command.
If I run a session of Windows Powershell, I do not have to import the module, the command is already there.
Anyone able to explain what is going on?
Thanks
You are not the only person having this problem. Unfortunately, I can't speak to whether any of the solutions there work, as neither the asker or anyone else has confirmed them.
Note: I had originally suspected this might be a problem with automatic importing through the WindowsCompatibility module, but it appears that it does not interfere with auto-importing of modules. In addition, as of PowerShell 7 the WindowsCompatibility module features are baked into PowerShell itself.
For whatever reason, WebAdministration may not be able to be automatically imported in PowerShell Core. There are a few reasons for this but they are mostly on the module side, and you can't change the behavior without modifying the module.
You can try setting $PSModuleAutoLoadingPreference = 'All' in your current PowerShell session, but generally that doesn't need to be changed from the default value of ModuleQualified. More information on $PSModuleAutoLoadingPreference can be found here.
If that doesn't work, you'll have to manually import the module in every session.
Fortunately, manually importing modules isn't required for the vast majority of them. For the ones which can't be automatically imported, you must use Import-Module MODULENAME in each new session. You can simplify this by adding the Import-Module cmdlet to one of the following profile locations:
$profile.CurrentUserCurrentHost
$profile.CurrentUserAllHosts
$profile.AllUsersCurrentHost
$profile.AllUsersAllHosts
For scripts, Import-Module should generally be done inside the script to prevent needing profiles in scenarios where profile loading is desired to be disabled such as when PowerShell is invoked in the following way: powershell.exe -NoProfile ....
In your case, it would like like so:
Import-Module WebAdministration
Here is some additional information about the $profile variable.

I'm trying to update a PS5 script to PS7, mainly because the script does work that requires a PS Core module.
Part of the script involved updating IIS bindings to use a different SSL Certificate. The cert is in the store and ready to be used - I just need to change the thumbprint on the binding.
My PS5 script used Get-WebConfiguration to get the bindings and then just looped through, calling RebindSslCertificate on relevant bindings.
I've tried using Set-WebConfigurationProperty and Set-WebBinding; neither errors but neither actually updates the binding with IIS - example:
Set-WebConfigurationProperty -Name 'certificateHash' -Value $newCert.Thumbprint -PSPath "IIS:\\" `
-Filter "/system.applicationHost/sites/site/bindings/binding[#protocol='https'][#bindingInformation='*:443:hostname']" `
Could anyone help point me in the right direction for what I'm missing?
Thanks,
Mark.
P.S., Apologies if this is a repeat question but all I can find is old stuff that doesn't work or relates to "-Set-Item IIS:\SslBindings" Maybe there is someway to get the IIS drive working with remoting?
Ran into this on 9/10/2021 using Powershell 7.1.4.
As of date of writing, this is an open issue on github for PowerShell.
Link for reference: https://github.com/PowerShell/PowerShellModuleCoverage/issues/14
Issue is that PowerShell 7 is based on .NET Core and the PS module WebAdministrator is based on .NET Framework.
When you run
Import-Module WebAdministration
WARNING: Module WebAdministration is loaded in Windows PowerShell using WinPSCompatSession remoting session; please note that all input and output of commands from this module will be deserialized objects. If you want to load this module into PowerShell please use 'Import-Module -SkipEditionCheck' syntax.
Notice the mention of 'WinPSCompatSession' in the warning. If the module manifest doesn't indicate that the module is compatible with PowerShell Core, then it gets loaded via the Windows PowerShell Compatibility Feature.
It seems this module partially works in compatibility mode, however if you try to work with IIS:\ then you start getting errors.
Alternatively, if you run the parameter in the warning you get this.
Import-Module -SkipEditionCheck WebAdministration
Import-Module: Could not load type 'System.Management.Automation.PSSnapIn' from assembly 'System.Management.Automation, Version=7.1.4.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'.
A quick test in PowerShell 7.1.4 will show you that you can't access the IIS connector.
PS C:\Windows\System32> Import-Module WebAdministration
WARNING: Module WebAdministration is loaded in Windows PowerShell using WinPSCompatSession remoting session; please note that all input and output of commands from this module will be deserialized objects. If you want to load this module into PowerShell please use 'Import-Module -SkipEditionCheck' syntax.
PS C:\Windows\System32> cd IIS:\
Set-Location: Cannot find drive. A drive with the name 'IIS' does not exist.
However, if you open up PowerShell 6 you can do this no problem.
PS C:\WINDOWS\system32> Import-Module WebAdministration
PS C:\WINDOWS\system32> cd IIS:\
PS IIS:\> dir

My next step is trying to get this to work by loading the .NET assembly directly. Will update with the solution
[System.Reflection.Assembly]::LoadFrom("$env:systemroot\system32\inetsrv\Microsoft.Web.Administration.dll")
I have a custom PowerShell module with two cmdlets. I have it successfully, but manually, deployed on my machine. However, I deployed it by placing the binary file and module manifest in a location, and then registering the module. I also had to manually write an Import-Module command into my 'all users' profile.
Now I am sure I can deploy this module with Publish-Module, but how do I get the Install-Module to write the Import-Module statement to the profile file?
As of PowerShell 3.0, a module is automatically imported when a command from the module is invoked. This was a brilliant on Microsoft's part; however, it did require that modules are located in a location where PowerShell looks for modules by default. Makes sense. You can see those locations by running the following command:
$env:PSModulePath -split ';'
Is there a reason you'd rather not use one of the paths stored in the above environmental variable? That said, I'd keep your code out of the "C:\Windows\System32..." path. The other options are better: "C:\Program Files\PowerShell\Modules" (AllUsers) and "C:\Users\tommymaynard\Documents\PowerShell\Modules" (CurrentUser). Depending on your PowerShell version/OS, those path could be different. You won't need to write an Import-Module command into a $PROFILE script if you get the module into a preferred location. Maybe you already know this, but maybe not.
You're not going to get Install-Module to write to any of the $PROFILE scripts.
$PROFILE | Select-Object -Property *
Well, not by default anyway. You could write your own Install-Module function, that runs PowerShellGet's Install-Module function, and includes writing to various $PROFILE scripts. The problem is that you'll need to include logic so you don't blow away the contents of someone's $PROFILE script if it's not empty, and only append to it.
Seriously though, this is turning into a lot of work, when you could drop the module into a location where PowerShell can find it on its own.
Edit: It just occurred to me, you can add a value/path to the $env:PSModulePath environmental variable. It's a single string with semi-colon delimiters:
$env:PSModulePath.GetType().Name
Therefore, it'd look like this:
$env:PSModulePath += ';C:\Another\Path'
That's great and all, but again how might you stage this, right? It takes you back to the write-to-all-the-$PROFILE-scripts problem,... although you may be able to update the variable via Group Policy Preferences. Again, probably better to just relocate your module.
Environment
I have the following folder structure where I keep powershell modules:
C:
PsModules
...
util
util.psm1 (this contains implementation of 'Test-Function')
util.test.ps1
ftp
ftp.psm1
http.test.ps1
...
There are about 50 folders and modules in c:\PsModules.
I have set environment variable PSModulePath to include c:\PsModules. This seems to meet the conditions for "well-formed modules" described in Microsoft's documentation and this answer.
Symptoms
Sometimes Test-Function is not found automatically when calling it from ISE. In fact, on any given fresh launch of ISE, there are always some (seemlingly unpredictable) modules that are not found automatically. The failure to automatically find Test-Function, for example, looks like this:
PS C:\> Test-Function
Test-Function : The term 'Test-Function' is not recognized as the name
of a cmdlet, function, script file, or operable program. Check the
spelling of the name, or if a path was included, verify that the path is
correct and try again.
...
+ FullyQualifiedErrorId : CommandNotFoundException
At first glance, this seems to indicate that util.psm1 is not "well-formed". If it were not "well-formed", then ListAvailable shouldn't work. But it does work:
c:\> get-module -ListAvailable util
Directory: c:\PsModules\util
ModuleType Version Name ExportedCommands
---------- ------- ---- ----------------
Script 0.0 util
PS C:\> Test-Function
...
+ FullyQualifiedErrorId : CommandNotFoundException
Furthermore, after calling Get-Command for the module, the commands in the module are available for general use:
c:\> Get-Command -Module util
CommandType Name ModuleName
----------- ---- ----------
Function Test-Function util
c:\> Test-Function
Call to Test-Function succeeded!
Questions
Is automatic discovery and module auto-loading supposed to be reliable and predictable?
How do I troubleshoot why powershell is sometimes doesn't find a command until a call to Get-Command -module?
Is it bad practice to rely on powershell to automatically load modules? If so, what is the good practice for automatically loading modules?
I can't speak to whether module auto-loading is intended to be reliable, but I personally do not rely on it in finished code.
If I'm writing a script or module, I always use Import-Module TheModule -ErrorAction Stop, and often use #Requires -Module AciveDirectory,TheModule,SQLPs to ensure that the modules are available.
For interactive use in the PowerShell console or ISE, I do generally rely on auto-loading, but if it fails I just Import-Module manually for the session.
In situations where I always want a specific module loaded for an interactive session, I load it in a profile. To see the various profiles run this (from both ISE and Console):
$profile | Get-Member -MemberType NoteProperty
You can decide where you want to place the code for importing the module based on which user(s) and in which host(s) you want the module to be available.
So far I only do this for posh-git, but it seems like it would fit your use case well.
In case this is helpful to anyone else, I think this may be a problem exclusive to ISE. I could not repro but recently went around with MS on inconsistent ISE workflow behavior and after some effort the issue was closed without a solution, with the official answer being to not use ISE which is not approved for production and instead use the native shell. It was a realistic answer for us, never saw the issues in native shell. I wonder if it's the same on this symptom?
I have found that the FunctionsToExport section in the module manifest cannot be set to *
THIS IS BAD:
# Functions to export from this module, for best performance, do not use
# wildcards and do not delete the entry, use an empty array if there are no
# functions to export.
FunctionsToExport = '*'
THIS IS GOOD:
# Functions to export from this module...
FunctionsToExport = 'Test-Function, Test-Function2'
Windows 8.1, PowerShell 4. I'm wanting to use PS to manage the GAC. I find lots of references to Get-GacAssembly for reading a list, getting detailed info, etc.
But running PS as administrator, and PS ISE, I get an error:
>
The term 'Get-GacAssembly' is not recognized as the name of a cmdlet
Do I need to CD to somewhere? How would I discover where to go to find the cmdlets?
The general answer to your question is that you must first install the module (by adding relevant files to Documents\Powershell\Modules or Windows\System32\WindowsPowershell\v1.0\Modules. Then, you should use Import-Module to load the cmdlets. Cmdlets in Windows\System32\WindowsPowershell\v1.0\Modules should be loaded by default. Script modules (e.g., modules that export functions) require at least RemoteSigned execution settings to run.
I'm learning PowerShell and I'm trying to build my own module library.
I've written a simple module XMLHelpers.psm1 and put in my folder $home/WindowsPowerShell/Modules.
When I do:
import-module full_path_to_XMLHelpers.psm1
It works. But when I do:
import-module XMLHelpers
It doesn't work and I get the error:
Import-Module : The specified module 'xmlhelpers' was not loaded because no valid module file was found in any module directory.
I've checked that the environment variable PSModulePath contains this folder. As it is a network folder, I've also tried to move it to a local folder and to modify PSModulePath but without success
$env:PSModulePath=$env:PSModulePath+";"+'C:\local'
Any idea on what could cause this issue?
The module needs to be placed in a folder with the same name as the module. In your case:
$home/WindowsPowerShell/Modules/XMLHelpers/
The full path would be:
$home/WindowsPowerShell/Modules/XMLHelpers/XMLHelpers.psm1
You would then be able to do:
import-module XMLHelpers
1.This will search XMLHelpers/XMLHelpers.psm1 in current folder
Import-Module (Resolve-Path('XMLHelpers'))
2.This will search XMLHelpers.psm1 in current folder
Import-Module (Resolve-Path('XMLHelpers.psm1'))
I think that the Import-Module is trying to find the module in the default directory C:\Windows\System32\WindowsPowerShell\v1.0\Modules.
Try to put the full path, or copy it to C:\Windows\System32\WindowsPowerShell\v1.0\Modules
I experienced the same error and tried numerous things before I succeeded. The solution was to prepend the path of the script to the relative path of the module like this:
// Note that .Path will only be available during script-execution
$ScriptPath = Split-Path $MyInvocation.MyCommand.Path
Import-Module $ScriptPath\Modules\Builder.psm1
Btw you should take a look at http://msdn.microsoft.com/en-us/library/dd878284(v=vs.85).aspx which states:
Beginning in Windows PowerShell 3.0, modules are imported automatically when any cmdlet or function in the module is used in a command. This feature works on any module in a directory that this included in the value of the PSModulePath environment variable ($env:PSModulePath)
I had this problem, but only in Visual Studio Code, not in ISE. Turns out I was using an x86 session in VSCode. I displayed the PowerShell Session Menu and switched to the x64 session, and all the modules began working without full paths. I am using Version 1.17.2, architecture x64 of VSCode. My modules were stored in the C:\Windows\System32\WindowsPowerShell\v1.0\Modules directory.
Some plugins require one to run as an Administrator and will not load unless one has those credentials active in the shell.
My finding with PS 5.0 on Windows 7: $ENV:PsModulePath has to end with a . This normally means it will load all modules in that path.
I'm not able to add a single module to $env:PsModulePath and get it to load with Import-Module ExampleModule. I have to use the full path to the module. e.g. C:\MyModules\ExampleModule. I am sure it used to work.
For example:
Say I have the modules:
C:\MyModules\ExampleModule
C:\MyModules\FishingModule
I need to add C:\MyModules\ to $env:PsModulePath, which will allow me to do
Import-Module ExampleModule
Import-Module FishingModule
If for some reason, I didn't want FishingModule, I thought I could add C:\MyModules\ExampleModule only (no trailing \), but this doesn't seem to work now. To load it, I have to Import-Module C:\MyModules\ExampleModule
Interestingly, in both cases, doing Get-Module -ListAvailable, shows the modules, but it won't import. Although, the module's cmdlets seem to work anyway.
AFAIK, to get the automatic import to work, one has to add the name of the function to FunctionsToExport in the manifest (.psd1) file. Adding FunctionsToExport = '*', breaks the auto load. You can still have Export-ModuleMember -Function * in the module file (.psm1).
These are my findings. Whether there's been a change or my computer is broken, remains to be seen. HTH
try with below on powershell:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted
import-module [\path\]XMLHelpers.psm1
Instead of [] put the full path
