Update Crisis !!

I used WSUS Offline to get all the XP updates after 2015 support ended. Somehow along the way I must have deleted the folder.
I did reinstall XP last week and used the work around to get automatic updates to work.
WSUS Offline can no longer download these updates and I wonder how much longer the work around will last.
Is there a way to get WSUS to work again?
I was thinking about going into Programs & Features click show updates copy the KB # and get them one at a time on microsoft update catalogue.
Is this a viable solution? Do I reinstall the updates in the order that they appear in Programs & Features?
Is there a global catalogue that can be bought on DVD or USB?
I would like to have both X86 & X64 global update packages.

there are a couple that still work for xp as of june 2022, fortunately for me, I had portup installed and saved the cache file so I can do a clean install and update offline,

 

I found WSUS UPDATE ISO on Internet Archives.
Windows XP Updates (WSUS Offline) : Microsoft : Free Download, Borrow, and Streaming : Internet Archive
I will test it tonight.

 

I'm not familiar with WSUS and only recently did my first clean install of Unofficial XP SP4 which came out great. Before I did all updates by hand.
Does the Unofficial XP SP4 not cover all the updates that WSUS offers?

 

I was wondering about SP4 myself and what all it actually updates.
I did find my copy of WSUS XP FILES on an old IDE HDD hiding in the closet.
WSUS still works for windows 7/ 8.1/ 10 but can no longer retrieve XP updates.
It generates all the global update packages and saves them as a file on your computer. It installs these updates according to the make & model of your PC without having to be connected to the internet.
WSUS Offline Update - Update Microsoft Windows and Office without an Internet connection
I have been using the same file for years on 2 really old machines that refuse to die.
I also have windows 7 & Office 2007 WSUS updates saved as well.
I will do the same for Windows 10 on its last day of life.

 

Thanks for the WSUS info. very interesting.
Regarding SP4 (And there are others on the forum more experienced and knowledgeable than me):

I gleaned the files form the archive.org site which offers different packages and individual files. Here's a copy of "COMPONENTS_REFERENCE.pdf" to compare.
