Need to download WIndowsXP Sp1a, SP2 and SP3 to flashdrive so can load it to stand-alone PC needing update for printer.

If you have Service Pack 1a already installed on your computer, you may go ahead and install Service pack 3

Else, you will have to download and install Service Pack 2.

And later you will have to install Service pack 3.

Service pack 2 has Service pack 1 and Service pack 1a integrated in it.

Here are the links where you can download and install Windows XP SP.

Service Pack 2: http://www.microsoft.com/en-us/download/details.aspx?id=28

Service Pack 3: http://www.microsoft.com/en-us/download/details.aspx?id=24

Hope this helps.

I'm the first "Me too",  tried the (appreciated) links but they both say for Networks and IT Pro's. 

Aren't  there  two  more  for  rank and file amateurs who don't Network? 

I'm XP Home, SP3, just used CNET'S  uninstaller (cleanup) download because Automatic Updates  kept saying  .NET framework 3.5 and I think part of version 2,  can't be installed.  Did a lot of searching before finding this site, and, looking for the Reinstall  links you probably know of,  while waiting  I'll  Probably check again at CNET, have a couple of Tracked discussions on this subject there.  Thanks in advance if you have the links, for novices. 

A  printer program is asking for  .NET 2 or higher, keeps saying my HP 28 color cartridge is incorrectly installed, but I've been installing for  almost two decades,  and after all  it's  printing, just has that annoying error message, needs the .NET.   Hope this helps  somebody  else besides myself.   

Give this a try.

Cameron's answer didn't work directly, but got me to the right area (microsoft and download).  DId a bit of trial and error ( a little counter-intuitive--have to say you want to download to computer you're using and then it allows you to save elsewhere) and got the downloads successfully to my flash drive, installed and updated my windows and my printer works great!

For anyone who must use XP, despite the fact that it hasn't been supported by Microsoft since April 2014 and is therefore increasingly vulnerable to malware.

You don't need Service Pack 1 or 1a.

If your version of XP has no service packs, you can install SP 2 and then SP 3.

If your version of XP has SP 1, SP 1a, or SP 2, you can install SP 3.

Once you have SP 3, all of the post-SP 3 updates issued up to April 8, 2014, should be available through Windows Update, although this could change.  Alternatively, see http://xdot.tk/

Several weeks ago, Microsoft pulled the old links for XP SP 2 and XP SP 3.  However, at least as of today, these are available through the Microsoft Update Catalog:  http://catalog.update.microsoft.com/v7/site/Home.aspx

If you use "XP Service Pack" (without quotes) as your search term, you will find:

• Windows XP Service Pack 3 (KB936929) 316.4 MB
• Windows XP Service Pack 2 266.0 MB

Unless you have Windows XP Professional x64 Edition, these are the files you need.  If you do have this rather rare version of XP, there is a SP 2 available.  There never was an SP 3 for this version of Windows.

If your PC is an HP Pavilion, Presario or Media Center and has an AMD processor, you need to install this patch before installing SP3 -->
