Additional XP patches

[RentedMule]

Hello,
I have been setting up a legacy development virtual machine running XP for maintaining old projects. To ease the update process, I grabbed WSUS Offline Update 9.2.1 and made an ISO.

Now, the updates it installs are not all of the updates available. It especially doesn't include the post-2014 POS 2009 updates.

Is there something more automatic to adding these additional updates to the WSUS Offline Update iso, rather than opening Windows Update and manually catalogging/downloading everything additional? I have memory problems that are making this exceptionally tedious.

Thank you
