Hello,
Rtm = Release To Manufacturing [it is supposed that which will be
launched to publicly very soon]
SP1 = Service Pack1
Windows XP updates are distributed in service packs. Service packs help
to keep Windows XP current, and extend and update the functionality of
your computer. Service packs are cumulative. Each new service pack
contains all the fixes that are included with previous service packs and
any new fixes.
The service pack1 has already been released.Infact Microsoft updated XP
SP1 to version SP1a (Feb 2003) and the only change they made was to
remove the JVM [which provides support for running Java programs]
To know more,see:-http://support.microsoft.com/?kbid=813926
If you mean RTM for XP Service pack 2 then it makes a sense.As it is
about to release RC2 followed by RTM in the coming months.
