Almost nobody still uses a Pentium III or Athlon XP, especially on POSReady or Windows 7. However, some people (including myself) have noticed the problem related to the recent updates on both operating systems if the computer hasn't a SSE2-compliant processor.
So, I suspect somewhere in the timeline, some updates required SSE. Perhaps .NET, I don't know.
Maybe your problem is related to .NET ? Depending on version, its hardware requirements are much higher than Windows XP itself.
According to Microsoft himself, Windows XP requires a 233 MHz processor and 64 MB RAM.

For .Net Framework 2.0, released in 2005, the official minimum is a 400 MHz processor and 96 MB RAM.

The last for XP, .Net Framework 4.0, released in 2010, is intended for a Pentium 1 GHz with 512 MB RAM.
I've suggested you reinstall Windows XP SP3 and the operating system hotfixes only. Do not install .Net Framework and keep the original versions of Media Player, Internet Explorer... Then, install other programs you want to determine why you experienced issue.

Finally, it's possible your problem is not related to SSE but any other instruction (AMD K6-3 can be seen as an enhanced 586 processor, and some P6 instructions can be missing in Cyrix MII-433. Perhaps you didn't experience any problem if you used an Intel Pentium Pro or a Pentium II, two i686 processors without SSE).
EDIT: someone has tested all system updates for XP SP3 on a Pentium 200 MHz MMX
Because some people had problems with the new XP updates on non-SSE-2 CPUs, I made a big test and installed WinXP SP3 and all up […]
Because some people had problems with the new XP updates on non-SSE-2 CPUs, I made a big test and installed WinXP SP3 and all updates (up to October 10, 2018 from catalog update) on my old 200 MHz Pentium-1 computer (P5 architecture with MMX support). .NET Framework 2.0 SP2 was installed, but not updated nor tested. Windows Media Player was not updated to v10 or v11 and Windows Search 4.0 was not installed.
The results are:
- Everything installed fine
- System booted up correctly
- Some updates failed to work due to SSE-2 requirement:
kb4340937 (august, 2018) - msi.dll (and may be msihnd.dll and msiexec.exe)
kb4343674 (august, 2018) - gdiplus.dll only
kb4458000 (september, 2018) - gdiplus.dll only
kb4462987 (october, 2018) - gdiplus.dll only
So the new gdiplus.dll and Windows Installer updates should be skipped on non-SSE-2 CPUs.
But not all installed files are executed by the system by default, so SSE(2) requirement of some of the other files is unknown. e.g. msvidc.dll, t2embed.dll, mf3216.dll, msxml3.dll, msxml6.dll, mrx*, MS JET files should be tested. MS JET seems to be compiled with MSVC12 (which is very uncommon for Windows XP files) - and most of (may be all) MSVC12 compiled applications I used required SSE-2.
