New-PSSession and Path consistency

PowerShell Help
1

I’m trying to understand why $env:path is inconsistent when I enter a new PSSession.

Consider this very simple example:

PS E:\> $env:path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;E:\Oracle\Database\db11204\oracle_db1\bin
PS E:\> Enter-PSSession localhost
[localhost]: PS C:\Users\user1\Documents> $env:path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\

I’ve found that $env:path in the new session matches that in the ControlSet002, but why?

PS E:\> (Get-ItemProperty -Path 'HKLM:\\SYSTEM\CurrentControlSet\Control\Session Manager\Environment').Path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;E:\Oracle\Database\db11204\oracle_db1\bin
PS E:\> (Get-ItemProperty -Path 'HKLM:\\SYSTEM\ControlSet001\Control\Session Manager\Environment').Path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;E:\Oracle\Database\db11204\oracle_db1\bin
PS E:\> (Get-ItemProperty -Path 'HKLM:\\SYSTEM\ControlSet002\Control\Session Manager\Environment').Path
C:\Windows\system32;C:\Windows;C:\Windows\System32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\

Any help is appreciated!

if you find a difference, for process this can be from powershell profile, for user - from user env and machine should be the same.
