That's standard - two updates a year.
I too had doubts about Win 10 & hung onto Win 7 with a laptop. Then had to get a new desktop, which came with Win 10 of course. Found that I liked it. Granted, there was the occasional glitch but nothing major.
The only big problem was an update that hung up in v1709, for 45 days! Rebuilt the OS, updated to v1803, & it's been smooth sailing ever since. Did the same to the laptop.
Even at work they have gone from 7 to 10, & you know how conservative institutional IT departments are.
