I finally had to set up a dual boot with Ubuntu so that I could browse the net in peace. The constant clicky-clack of my hard drive drove me nuts. Windows lately has not given it a rest. Ubuntu on the other hand hardly ever causes overuse of the hard drive. Windows needs to get a handle on this problem..
"It is not a bug, it is a feature."
Seriously, Windows has many tasks to improve functionality, which cause HDD activity, like indexing, superfetch, cortana/search, windows defender, smart filter, not to mention various logging being sent to MS to improve user's experience. You have to customize it the way you want it, like in Ubuntu, mine Windows is calm.
Mine is calm too after a while, maybe 5-10 minutes. Check your startup items and services.
For the record, this is my HDD's activity after startup. 10 only checks for updates and that is it.
You should look, which processes cause the activity and then you can do something about them.
