I have the same specs in my work machine.

Task manager takes 10 seconds to load the list of processes. Right-click on the desktop takes about 1.5-2 seconds to show the 'new' context menu. Start menu is actually fast to start drawing but has a stupid animation that takes about half a second to fully load.

I sort of understand how the anti-consumer 'features' (ads) get added to a piece of software. But I have no idea how they manage to continuously degrade the experience of existing parts of the system for seemingly no one's benefit.
