So I have a windows 10 dell laptop which is 64 bit and recently I was going to my C:\ drive to delete the windows.old folder but I noticed another folder called WCH.CN with another folder inside it called CH341SER and I wanted to delete this folder as I am not familiar with it and what it does so it is okay to delete WCH.CN folder?

You can safely delete that folder. It is the location where the setup program for the "CH341 (USB=>SERIAL chip) V3.4" driver is decompressed.

That driver is used for a USB controller commonly found on 3rd party Arduinos.
