My primary computer is an 8 year old 2.4GHz laptop computer with the same 8Gb of RAM and it is at least 5 times faster than this Intel i5-4570 3.6GHz computer.  The only thing I can think of is there is a special BIOS running that hides the fact it's really 500Mhz Pentium II or that there is so much custom spyware that there is no CPU time for Windows. Every thing you click on has a 30 second delay before running (not new programs opening mind you, but elements of already running programs). I think I might have to pull the Windows 10 key out of the BIOS and try reinstalling it clean. I only hope it's a real copy and not running some sort of hack. It performs like a single core 1Ghz computer, I have never been so frustrated waiting for Windows to respond, even in 1998 Windows 95 on a 600Mhz computer was more responsive than this thing. 3 stars, because after all it's a mostly functional computer for $165, but my god, you may very well give yourself a stroke screaming at how horribly responsive it is.UPDATE:  I replaced the original harddrive with a SSD and reloaded Windows 10 on it and that fixed all the speed issues. I don't know if it was the pre-loaded software (who knows what they had loaded in it), misaligned partitions or just the old spinning 5200 rpm harddrive but it's speedy and working fine now. The OS key is burned into the BIOS so if you can download Windows 10 onto a USB drive it will let you reload it just fine.
