As i said in Post#9, the layout.ini sometimes also conatins info. abou programs that are un-installed and these simply take extra place in the layout.ini file.
So even the layout.ini file has to be cleared after sometime.
And to aviod the slow boots till it is re-created, you can use the commnad in Post#9 to immediately re-create it.
The first command worked but the second didn't?
