How can I remove Windows Path from Ubuntu Path ?

~/.bashrc or other file does not contain it.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss = "AppendNtPath"=dword:00000000HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Lxss{....} = "AppendNtPath"=dword:00000000

It has no effect.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Lxss{GUID}\Flags

Change flags from 7 to 5, has reset my Ubuntu eliminating everything I had.
