PowerTip: Turn Off PowerShell Module Autoload

Summary: Learn how to turn off Windows PowerShell module auto-loading.

Hey, Scripting Guy! Question I want to disable the Windows PowerShell 3.0 module automatic loading of modules. How do I do this?

Hey, Scripting Guy! Answer Set the value of the $PSModuleAutoloadingPreference automatic variable to none, as shown here.

$PSModuleAutoloadingPreference = "none"

Note   I do not recommend you make this change except in very specific situations and for very specific reasons. The number of Windows PowerShell cmdlets and functions in Windows Server 2012 and Windows 8 would make knowing which module a particular command resided in extremely difficult; with this change in place, you have to specifically load the module prior to using any commands.

    SG; Love your blog! I’ve been following for a long time and no matter how my skill progresses I still find relevant material here! Here’s something I hope can add value to your post. It’s real handy to have modules automatically load, like when I’m looking
    around for a cmdlet. I just start typing get-somenoun and hit tab until it shows me something close, it’s great! But I have tons and tons of modules on my management workstation where I do more administrating and less hunting and pecking (that is, by time
    I’m on my management machine I usually already know what I want to do). When auto loading is enabled it really slows down tab completion. Sometimes it even hunts for a module when I’m running custom functions, slowing them down, also. So I wrote this function
    to make it easy to configure (that is, I don’t have to come to your page because I can never remember the variable name $PSModuleAutoloadingPreference, and I already have plenty of reasons to come visit your blog). I put this in my PS profile and now changing
    the setting is as easy as typing set-au 🙂 Anyway, here’s the code! I put the other possibilities in a ValidateSet so the Mode param will tab complete, too. I hope someone else finds it useful! # set autoloading modules function set-automod { param([ValidateSet(
    "All","None","ModuleQualified" )] $mode = "None") # All, None, ModuleQualified: mymodulecmdletname $PSModuleAutoloadingPreference = $mode $outObj = new-object psobject -property @{ PSModuleAutoloadingPreference = $PSModuleAutoloadingPreference } $outObj }
    function get-automod { # All, None, ModuleQualified: mymodulecmdletname $outObj = new-object psobject -property @{ PSModuleAutoloadingPreference = $PSModuleAutoloadingPreference } $outObj } Here’s what the output looks like: PS C:> get-automod PSModuleAutoloadingPreference
    —————————– none PS C:> set-automod -mode ModuleQualified PSModuleAutoloadingPreference —————————– ModuleQualified
