No matter if I am using 7zip or WinRAR, 20gb took me around 4 hours, Installing a game through a .exe setup file takes ages too, my friends extracted the said 20gb for abour 20-30min.

I tried putting exceptions on my defender, didnt work. Winrar is set on high priority, didn't work. I turned off Defender, also didnt work. Could it be HHD issue? Ive noticed that moving stuff to another folder also take a bit of time. My pc isn't that old, i bought it 1 year ago brand new.

I don't know if if its because i have an SSD but in the task manager, in the Process tab disk is 50% but on Performance its 100%, reading speed didnt rise more than 10mb/s, it was constantly some KBs.
