I've use RyanVM's Windows XP Post-SP2 Update Pack with my nlite install and now get a right click option of "who lock me ? ..."

What does this do? and how can i remove it?

Very useful when you get the "Error Deleting File or Folder, ... There has been a sharing violation. The source or destination file may be in use." message. Integrated into the shell and select the program!

I'd rather have the program stand alone (with a nice gui) instead of having it integated into the shell. Very usefull tool but it just clutters things up and I only rarely need it.

RyanVM has a forum for his pack and it's answered there on how to remove it.

You can always use the Lite pack as well if you don't want any frills.

And like Smeeeprig, please take questions like that to my forums to keep discussion in one place instead of many.
