As with most versions of Windows, it depends on what processes and services you leave enabled / Auto.
Win10 wants to have a lot more forced to auto than a lot of previous versions, and setting some to manual or disabling them is very difficult without hacking the registry or taking ownership of files/folders/services.
Bear in mind I'm talking about Home version, and not other version(s) that allow for group policy settings (gpedit is disabled on Home versions).
I'd take a peek of all the processes and services. Set to manual if possible, any that look unlikely to be used by you. If they want to kick in, they can. If not, they don't use resources needlessly.
Also appreciate that Win 10 is more hungry than previous versions, and with automatic updates / monitoring etc it's likely to be using your network connection more, and especially after a period of downtime.
As a result of all this activity, a system built in 2015 might see more activity compared to a system built in 2019. Faster storage, faster RAM and a faster CPU will minimise that effect. No idea how new your system is, but my Win10 system has an NVME C: drive, and it's mighty fast. From POST to desktop is under 5 seconds. My 2015 SATA SSD (fast for its tech) takes about 20 seconds on Windows 7.
