Windows 10 operating systems come with pre-loaded apps and many of these apps run in the background. This may also cause your machine to run slower.
To see what apps run on your machine, search "background apps" and select the first option you see.
You will go to System Settings > Background Apps and can see what apps are running in the background on your machine. Here you may also turn off and on these apps.
Personally, I have most of them turned off.
