A different system will read that registry key value. That being said, is there a way to read the value from a registry key and write that value into a different one?

For example

Read the value from CLIENTNAME

HKEY_LOCAL_MACHINE\SOFTWARE\ CITRIX\ICA\SESSION\CLIENTNAME

Write the vale to the Winlogon key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon

If Set-ItemProperty writes to the registry, I would look at Get-ItemProperty to read from it.

I find the docs are a great place to look for these things:

Can you execute that PowerShell script as the logon script for the user without local admin rights?

Set-ItemProperty -Path 'registry::HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon' -Name DefaultUserName -Value $env:UserName

I don't know. Try it and see.

Some registry values can be user updated and some need elevated permissions. I don't have a list of what is what.

You should be able to set up some login event at a system level that could probably run it when a user logs in. I'm not a Windows Admin so I can't tell you what your options are.
