Steps to reproduce

Environment :

I am currently using Windows 11 Professional and Enterprise (FR-fr) 25H2, a fully up-to-date version.

Explain :

After migrating from version 7.5.4 to 7.6, I received the message "Get-WindowsOptionalFeature class not registered" (french message in my case) when my script tried to retrieve the list of offline options from an image mounted by DSIM.

So I first tried running the script on version 7.6 to verify the command directly on the online version. It executed correctly, but after a while, it returned absolutely nothing. Then I uninstalled version 7.6 and installed version 7.5.5 instead, which correctly retrieved the data.

To Reproduce in administrator mode :

Note: I have restricted the list of options here to reproduce the case (this command take a time), as I normally load them all.

Get-WindowsOptionalFeature -online -featurename Hyperv*
