Litestep is a replacement shell for windows, when you do the initial installation litestep changes your system.ini file, primarly the line that use to say shell=c:EXPLORER.exe and now is changed to point to litestep and says shell=c:\litestep\litestep.exe. It is a good idea if you go over to: http://lsdocs.shellfront.org/index.php

and take a look at the documentation that they have written, This will help you understand the change that has been made, how to correct it, and also warn you about making changes to the themes before you understand the structure of the litestep resource file. Litestep is a fantastic and stable shell replacement, and I have been running it a years without a single conflict, but I do recommend you read the manual before making changes.

In addition to what my esteemed coleagues have said, all I can say is: RTFM. Don't blame the devs for your negligence.

When all else fails, you can go back to your regular WIndows shell by editing the system.ini file.

If your reference to 'XPerience' means you are using XP, then system.ini will not help you. XP is NT based, as is Win2000...and all three of these access the shell via the registry settings, not via sys.ini.

If this is your case, simply use a shell loader such as ShellON, which will handle the reg settings for you, and enable simple and easy switching between LiteSTEP and Exploder [if you must].

There is no need to burn servers, etc, nor is there a need to re-install Windows....just RTFM, listen and learn....
