Windows XP Service Pack 3 (XP SP3) is available for download from the OSL SupportFTP server.
This is the full 324 MB "Network Installation Package for IT Professionals and Developers" file. Using this file allows you to download SP3 once, and then install it on multiple computers. This local download minimizes Internet bandwidth usage, because the server is inside the OSL network. (E-mail Rick for the FTP login & password).
It takes about 15 to 30 minutes per machine to upgrade to SP3, using the full network installation package.
(The "web download" of SP3 is available from Microsoft Update, but takes longer to install on each computer - typically 40 to 60 minutes - and you have to download it for each computer that is upgraded.)
SP3 is the first service pack for XP since 2004. It is also the last service pack that Microsoft will release for Windows XP.
I am available to do SP3 upgrades. Just send me an e-mail to set up an appointment.
