Darvond: Opinion: Why bother at this point? By the time the support fee comes into play, the OS will be 11 years old by that point. Users have already been given excess time to consider other options, and driver support will be rapidly drying up for the system. Already, several CPUs are are outright incompatible.
That depends on the user. There are a lot of applications where platform stability is priority over everything. On the hardware side, "CSM" (Corporate Stable Model) versions of motherboards do exist that continue to be made 3-5 years after everything else. Eg, whereas B150/H170/Z170 motherboards are already end of line (and B250/H270/Z270 to follow next year followed by Z370 when Z390 comes out), it's still possible to buy H110 boards and even H81 (Haswell) boards for simple replacements that don't screw up an enterprise's unified deployment model.
On the software side, you have applications such as medical equipment, ATM's, security & defense computers, critical infrastructure (power stations, etc), which only upgrade to a new OS on a delayed cycle after that new OS has proven mature. All versions of W10 except for Enterprise LTSB have failed miserably at stability due to MS's constant messing about with forced bi-annual feature updates that consistently break more than they enhance even for those with brand new hardware. "But the software is +5 years old" is simply another way of saying "stable platform". The OS on my microwave, cooker, refrigerator, washing machine, MP3 player, DVD player, thermostat, radio, printer, etc, are also +5 years old too. But if the user's needs are static and don't require hardware changes, that's perfectly normal. It's artificial obsolescence that comes from "Software As A Service" that's the fake "upgrade".
As for consumers, if W10 Enterprise 2016 LTSB were the main consumer branch by default, "feature" updates were optional not compulsory and they dialled way back on the spyware (inc Cortana), telemetry and "Windows Store In Your Face", then many of us W7 holdouts would have switched already. As usual though, Microsoft fails to understand everyone else's needs except their own. Personally I find W10 so unpredictable and unstable from one year to the next that if all existing games ran under Linux, hassle free, and with no performance penalty, I'd have switched to that and ditched Windows already. We already made the MS Office to LibreOffice jump 2 years ago without regretting a single day.
