Document usage of LSWITCHD TSR

[Lewis Rosenthal]

I have been using:

LSWITCHD.EXE /SH

in my AUTOEXEC.BAT for well over a decade. I have no recollection what the /SH switch is supposed to do. The TSR itself has no built-in help (e.g., LSWITCHD /? doesn't work), and apparently, there is no /U switch to unload it from memory (which isn't a big deal).

There is no mention of proper placement of the executable or how it works (it does nothing itself other than access lswhook.dll). It isn't very useful in DOS windows (but again, this isn't documented anywhere).
