I am sticking with Kixtart. There is nothing to install, it allows a much faster logon than group policies which are so slow in comparision and I like the fact that its not a Microsoft virus prone scripting language.
The big one for me, is that the kixtart language is very user friendly. It is the perfect program for running logon scripts which is what I use it for.
Also a great advantage of kixtart is the very friendly environment on the kixtart board. Its a positive joy to come online onto korg.
