Are you sure that it is Windows Live Mail that is using all the CPU, and not
something else? That is, have you run the task manager or a similar program
to see that Live Mail is using all the CPU?
I have seen cases in which starting a program will cause an antivirus
program to take over a PC. The problem is not the first program, but how
the antivirus reacts to it. This can be tested by first turning off your
antivirus, then opening Windows Live Mail. Of course, do not open any email
attachments, while your antivirus is off.
And, have you tried turning off all other application programs while you are
running Live Mail? How about all those background processes associated with
the other programs you have available on disk (e.g., antispyware, spam
filter)? Any one of them could be triggering an adverse interaction.
Another thought is whether you have multiple CPUs? If so, you should be
able to set the "affinity" for a program to use only one of them, instead of
all of them. Note that "affinity" is different than "priority", but is
usually set via the same method.
Finally, if a program is operating oddly, the usual wisdom is to
uninstall/reinstall. If that fails, replace it with another similar
program. There are many free mail programs. Take a look at the following
