Moreover, going back to Win98 wouldn’t help, unless you also went back to an ancient version of NPP. NPP hasn’t supported Win9x for many versions, and is even moving away from supporting XP.
And in all good conscience, I cannot do anything but strongly recommend not going back to an operating system so old and insecure as that. From my experience, Win10 isn’t significantly different from Win7, and anything that I cannot intuitively do via my Win7 methodologies, I can easily accomplish after a quick web search.
