The term 'Invoke-WebRequest' is not recoginzed as the name of a cmdlet

Question

I've got problem with executing Invoke-WebRequest cmdlet. I read that ~100% case of that scenario is PS version lower than 3, but it's not my case:

Name                           Value
----                           -----
WSManStackVersion              3.0
PSRemotingProtocolVersion      2.3
CLRVersion                     4.0.30319.34011
PSCompatibleVersions           {1.0, 2.0, 3.0, 4.0...}
BuildVersion                   10.0.10208.0
PSVersion                      5.0.10208.0
SerializationVersion           1.1.0.1

I can add that I'm using Windows 10 IoT Core version of OS. In fact my main purpose is execution of simple web request, but I am interested why this cmdlet is not working, especially if more of them won't be ;/ I suppose it can be some windows feature like switch to turn on, but its just my guess.

Update

As far as I compared available cmdlets for certain modules, and preloaded assemblies between my regular system and an IoT version, it looks like the latter version is cut somehow, but I still didn't see any docs for that.

Answer 1

I had this issue on a Windows Server 2008 R2 server, because it was running PowerShell v2. Upgrading to v4 fixed the issue.

Windows Management Framework 4.0 (includes PowerShell 4.0)

As of v5, Invoke-WebRequest is still documented.

Check your version with:

$PSVersionTable.PSVersion
