In addition to this, many products come preinstalled as bloatware. McAfee products (amongst a hoard of other programs) have come preinstalled on Windows laptops I've purchased from Dell and Lenovo.
The "Fresh Start" feature in newer builds of Windows 10 (1709-onwards if I'm not mistaken) will automatically remove these kinds of applications preinstalled on new systems.
Excellent feature in itself, but also a cludge around a broken economic system. OEMs shouldn't be prioritizing their profits at the expense of the users their business exists for.
