What's your definition of an "age"? I have an ancient Lenovo laptop (c2007) sporting 2GB RAM and it starts Win10 from a hard drive in 45 seconds to the log in screen and usable in less than 3 minutes. That's for a plain Win10 installation, not a laptop manufacturers installation.
You might want to look at all the extra crap Toshiba has lumbered you with loading at startup before you blame Win10.
FWIW Ubuntu is usable in 1:20 on the same laptop.
