Retrocomputing has blasted off into a larger hobby as of late. I think it's a combination of COVID free time in 2020, plus the demographic that grew up with early Windows is now old enough to appreciate the OS more and wants to re-experience it with modern tools and knowledge.

I don't personally install Windows 98 nearly often enough to justify a tool like this, regular vanilla installs are fine with me. But some do a lot of benchmarking and testing on modern hardware, e.g. user "O_MORES" has a configuration to run Windows 98 alongside Windows 11 and frequently expands it.
