• install-docker-ce.ps1 should install the Windows feature Microsoft-Hyper-V, not the non-existent Windows feature Hyper-V. See https://github.com/microsoft/Windows-Containers/blob/6ace4f158e85674df5a246f7173ecf1109234d74/helpful_tools/Install-DockerCE/install-docker-ce.ps1#L306
• Currently, if the following command is executed only in PowerShell 7,

Invoke-WebRequest -UseBasicParsing "https://raw.githubusercontent.com/microsoft/Windows-Containers/Main/helpful_tools/Install-DockerCE/install-docker-ce.ps1" -OutFile ./install-docker-ce.ps1
./install-docker-ce.ps1
docker run hello-world:nanoserver

• This will result in the following error log:

PS C:\Users\lingh> docker run hello-world:nanoserver

Inspect helpful_tools/Install-DockerCE/install-docker-ce.ps1 around line 306 and compare the Windows feature name used there with the issue's PowerShell command. Verify the installation flow in PowerShell 7, then run docker run hello-world:nanoserver; done means the script enables the required feature and the container starts without the reported error.
