some of my software lifetime license key purchases I did several years ago (usually more expensive) are starting to pay off since most stuff moving to subscriptions or 4-5x time more expensive. Was just recommending a software to a friend, I paied 19€ in 2016, it now costs 99€ + 19/year for updates. Luckily either many companies honour the free updates or Windows is stable enough with retro-compatibility.
