Why did it take such a long time for windows to boot up back in the day compared to today’s operating systems?

I understand that processing power was lacking but surely the os of yore must have had much smaller requirements. Also let’s assume we are booting up offline and no updates are indicated. What was Windows doing for 3 – 5 minutes that my android phone manages to zip through in 15 seconds?

Spinning hdds were not very fast when accessing data files. Your phones and most computers now days boot entirely from ssd or ram so they have very fast boots compared to old machines. I reduced my boot times from 35-45 seconds to 5 seconds when changing my hdd to a ssd.

Also, older machines tested every bit of ram during the post, which slowed the boot significantly. Many modern motherboards can skip to ram test to reduce boot times.

Don’t forget, win 10 and 11 don’t “shut down” when you click shutdown in the menu, they suspend for fast booting.
