Though not necessarily a microsecond *precision*-- beware!

A tool already exists that can do this; it's called `sed'.  It's a
little complicated, but probably something like this will work:

sed "s/^Wallpaper=.*/New Contents Of Line/" <win.ini >new-win.ini

This translates as:  Read contents of `win.ini', replace occurences of
["Wallpaper=" at the beginning of a line followed by anything] with "New
Contents of Line", and write the result to `new-win.ini', which you can
then rename over `win.ini'.

Those who do not understand `sed' are doomed to reinvent it.  (--Some
