Steps to reproduce

PS C:\test> cmd.exe /c "powershell.exe -command ""New-TemporaryFile"""

Expected behavior

Command to success and return a temporary file path

Actual behavior

Error of "The term 'New-TemporaryFile' is not recognized as the name of a cmdlet, function, script file..."

Environment data

PowerShell 7.1 on Windows 10 x64 version 2004 (for pwsh.exe)
Windows PowerShell 5.1 (for powershell.exe)

Note

When callingPS C:\test> powershell.exe -command "New-TemporaryFile" the command works as expected. It seems that when passing through cmd.exe or ::CreateProcess() the Microsoft.PowerShell.Utility assembly somehow is loaded differently and a few commands, including New-TemporaryFile end up missing.

New-TemporaryFile is available both on PowerShell 7 and on Windows PowerShell 5.1 so this is quite an interesting behavior
