What a great thread, it's been so helpful!
I did a clean install of Windows XP, I have removed all the updates mentioned by ED_Sln, I'm not on a SSE2 CPU.
Updates not requiring SSE2, replaced by updates requiring SSE2: KB4087398, KB4463361. Is it safe to install these from the update catalog?
I didn't see any KB4487085-v2 update, only KB4487085, didn't install it, does it work without SSE2?
KB4493563 mentioned in another post, is this safe?
