I would not do the one through windows update and go online with out the protection especially since you said you had a problem with it when doing it that way before. The stand alone file you simply select to download it to your pc, to like your desktop or where ever you choose, then once you have the internet connection disabled and have your security programs off then go to where you downloaded that file to and double click it to begin the install of it. Yes you can remove IE8 through add remove before you do sp3 and it will go back to IE6, then as soon as you are back online (with your security programs back on) from the install of sp3 go immediately to your windows updates site and get any other updates and you should be offered IE8. the guidelines link Windows XP Service Pack 3 (SP3) Installation Guidelines where to download the stand alone sp3 file from, click the download button and save to your pc, ignore any info there saying it is for IT professionals and not for single pc, this is the only download and is the one everyone uses when not doing it through windows updates. Windows XP Service Pack 3 as to foxit reader, it is a much better choice than Adobe but you do have to make sure it is always updated to the latest version because it also has been targeted by the bad guys. Opening pdf files online has always been a bad habit that is not something new but now more are hitting it with some bad exploits. So whether or not you choose to continue opening them online would be up to you. Since you have foxit now have you removed the Adobe Pdf reader? if not you do still need to keep it updated because having any program on the pc that has not been updated can be a security risk.

Outlook 2002 = Outlook XP. Currently Office 2002 or XP is up to Service Pack 3 or SP3 for short.

Jane no doubt it will be an Apple commercial if it is not already! I saw one last night that could have been about this reboot over and over situation, have to admit those commercials are funny. IF you have your computers fully updated with all the windows updates and you do not want to tackle this now you do not have to (totally up to you), this is not a super critical update like sp2 was, it is rated moderate. There are some additional changes it makes to the system itself which microsoft would like people to install. But I know a lot of people have decided to at least wait some time to see if there might be some hotfixes that come out to handle some of the issues that are cropping up and there has been discussion in the microsoft forums that this time they may actually put out a hotfix for some of the problems prior to pushing out sp3 in auto update. So waiting is not a bad idea at this point. I would suggest though that you uninstall your IE 7 through add remove before you do install sp3, because if you do not you will not be able to do so at any time in the future and it also affects the ability to try to do fixes on IE7 should they be needed. You can just take it out, put in sp3 when you decide to, then put IE7 back. Or just stay as you are and continue getting your other regular critical windows updates. It is your choice. At this point in time they will not stop you from getting your windows updates just because you do not have sp3, so don't be concerned about that.

XP SP3 is just under 350 megs in size. If you are into working on computers even in a modest way you should download SP3 and burn it to a CD for any future needs, I keep 2 copies in case one gets damaged and blank CDs cost mere pennies. You should have installed it first then gone looking for updates because many of the SP2 updates would be included in the SP3 file. After installing SP3 you should expect a minimum of 127 updates - that was the number I had when working on an XP macine a little while back. If I remember correctly the option to update to IE8 was offered after the updates were done.
