-MountUserDrive parameter description mentions wrong path

Prerequisites

• Write a descriptive title.
• Search the existing issues.
• I am reporting the documentation problem for version of PowerShell I am using.

Version

7.2

Link to affected document

https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.core/new-pssessionconfigurationfile?view=powershell-7.2

Description of the documentation error

-MountUserDrive describes that default path to be created is:
$env:LOCALAPPDATA\Microsoft\Windows\PowerShell\DriveRoots\
however that's likely false, the correct path seems to be
$env:SYSTEMROOT\System32\Microsoft\Windows\PowerShell\DriveRoots\<HOSTNAME>_<USERNAME>

I'm not sure if that applies to Windows PowerShell only or to PS Core as well?

I figured that out from another github issue below:
#5969

Suggested fix

Update -MountUserDrive description to point out correct default path for each edition of PowerShell.

The docs are correct.

For each user connecting to the endpoint, a folder is created with the name $env:USERDOMAIN_$env:USERNAME.

For computers in workgroups, the value of $env:USERDOMAIN is the hostname.

I also fixed the path difference between 5.1 and 7+.

I updated the article.

I'm sorry to reopen but there have been misunderstanding.

the issue is not $env:USERDOMAIN_$env:USERNAME but rather $env:SYSTEMROOT (correct) vs $env:LOCALAPPDATA (incorrect)

I tested path creation and it is created in SYSTEMROOT no in LOCALAPPDATA.

EDIT:
Ah it seems like your change is not immediatly pushed, all OK!
I was looking at old site it seems.

Investigating

[michaeltlombardi]

After investigation, I have discovered:

1. The described root path for the mounted user drive, $env:LOCALAPPDATA\Microsoft\PowerShell\DriveRoots, is accurate for Windows PowerShell 5.1 and all versions of PowerShell 7+.
2. The described per-user path after the root is incorrectly described for Windows PowerShell and incorrect for PowerShell:
   • For Windows PowerShell, it should be ${env:USERDOMAIN}_${env:USERNAME} as the listed $env:USERDOMAIN_$env:USERNAME will return only the username; the first component of the string will look for the environment variable $env:USERDOMAIN_, not find, and interpolate $null. For clarity, this should be updated.
   • For PowerShell, it is actually $env:USERDOMAIN\$env:USERNAME as a folder is created for the domain itself and then one for each user.
