Hopefully this will be popular enough that Steam and Mozilla and others won't drop Win10 support for several more years.
compared to buying a new machine that's actually not that bad. i am not a windows user but spending $180 to extend the life of a fairly new machine by another three years may just be worth it.
It's the same situation as last time with Windows 7. You can get three years of extended support for the monthly cumulative update, which I assume is being done given it is fairly inexpensive. The US government gets favorable pricing from Microsoft.
The consumer price for Windows 10 ESU is $30/$60/$90 for the first/second/third year.
