Adding App path to the Windows path variable

I would like to retrieve the value of HKEY_CURRENT_USER\Environment\PATH from Win10XPE Build (Target folder) and append an app path to the end (if not appended), then write the new value back in to XPE registry.

How can we process it?

Any help please.

This is how I do it 

Code: [Select]

[Variables]
%AddPath%=c:\this\new\Directory
[Process]
RegHiveLoad,Tmp_System,%RegSystem%
RegRead,HKLM,"Tmp_System\ControlSet001\Control\Session Manager\Environment",Path,%CurrentPath%
RegWrite,HKLM,0x2,"Tmp_System\ControlSet001\Control\Session Manager\Environment",Path,"%CurrentPath%;%AddPath%"
RegHiveUnLoad,Tmp_System

This is how I do it 

Code: [Select]

[Variables]
%AddPath%=c:\this\new\Directory
[Process]
RegHiveLoad,Tmp_System,%RegSystem%
RegRead,HKLM,"Tmp_System\ControlSet001\Control\Session Manager\Environment",Path,%CurrentPath%
RegWrite,HKLM,0x2,"Tmp_System\ControlSet001\Control\Session Manager\Environment",Path,"%CurrentPath%;%AddPath%"
RegHiveUnLoad,Tmp_System

Thanks Malok the the answer. I needed this to add Python to system path and also put the same lines as you did

You are welcome,

Wow! Your information is very detail and includes almost all possible features.

My goal is to use the Core of Python so that it is enough to run python script from command line by using standard libraries.
So, to have a full support with all features of Python (dev, pip, docs, tcltk...) we need to add all your codes to.

Thanks again for your time to figure out the detail registry entries.
