The log is nothing more than a history of what has happened when
Windows/Microsoft Update attempts to update.
If you Download and install a Service Pack or update manually it will not be
in the log since Windows/Microsoft Update was not involved.
Normally nothing will delete entries on the log and nothing searches the log
for other update information.
