On Windows 10 CU I can still run Soloway's Task Scheduler for one. (I always loved that program, totally configurable and command line accepting. I use it to schedule a time to fire up some Flash Timers and counters (Full Screen) I made on XP. General File Finder for two. And some Windows 98 screensavers pop out better than ever now. I'm sure there are others in storage and on the net that I haven't tried yet but if they are still useful with no serious memory leaks, and Windows will let it, I still like running those 98's on modern systems.
