Okay, reinstall it
Nothing says you can't run DOS, WordPerfect, dBase, Lotus 1-2-3, and Harvard Graphics. Bill Gates has never held a gun to someone's head and forced them to buy a new version of Windows. Yes, Microsoft discontinues support for products, but that doesn't mean those products quit working. It means new hardware and software probably won't run your old OS, but if you're happy with your old apps, that shouldn't be an issue. Your skill set will get out of date, but that's also beside the point.
Don't buy the new bloatware; lots of companies haven't. Feature creep isn't unique to Windows software; it's basic marketing. How many people used their VCR to record 12 programs over 21 days, can adjust the timer on their sprinkler system, or use the "Reheat" setting on the microwave? "If you're happy with it, why upgrade?" asked the man who works where Office 97 is still the default suite.
