It's quite obvious: you don't have an executable `egrep' (egrep.exe,
egrep.bat, egrep.cmd, etc.) anywhere on your PATH.

If you don't have GNU Grep installed, that's the problem.  If you do
have it installed, I'm guessing that `egrep' there is a Unix shell
script, and Windows doesn't know how to run it.  I suggest to write a
batch file egrep.cmd, with these two lines:

@echo off
grep -E %*

put it somewhere on your PATH, and then M-TAB should work for you.
Did it?
