HP Desktop 5082vS3 (750-114) really sluggish now, mostly due to Chrome and Edge, Firefox somewhat. Really bogged down. 12 GB RAM, 64-bit PC, Windows 10 (OS 17134.523). 1.7 TB storage free ... PC probably 3 years old.
Lots of Windows / tabs open, but I do the same at work, and my no-brand gov't desktop runs fine and CPU, Memory, and Disk are all good.
I don't do anything fancy, how can I clean this up? See attached. Not sure what "Disk Usage" is and why it's often at 100% or pretty high.
