FWIW....
My lappy ( Surface Pro 3 -SSD- i5) goes a bit nuts with the I/O after startup. Always has, any Win version. 99.9999% of the time it's this process. MS loves to keep you synced. It will go on and on for 20-30 minutes and settle down. Next time, check Task Manager (if you can ) and see what this is doing.
