I have autell diagnostic gear that is expensive and need xp to load diffent software for different car models onto it using xp 32 bit also peugeot plannet and citroen lexia, all needs 32bit xp, i had csm mode enabled but no go.
I am in a similar boat. I have several XPs / Win7 dual/multi boot PCs and laptops, all with spare MBs etc. Full images of all of them. Luckily, never had a failure.
I have developed many dozens of emulators / dev tools / UPC / MPC / programmers, many machine code level, even modified some kernels, 10s of $1,000s worth.
Happy to retire them once I croak :-) .. Keep ONE win11 laptop for rare cases, rarely need it, there's usually always a way around :-)
