text: how do i find out what someone has been doing on the computer? i know you can check the history or view archives in messanger but is there anyway you can still find out after they have deleted it? like in the registry or someother way? it's not good spying other's computer.but if you want to know if your husband or others do bad things on your computer,u can use the software just like keyboard recorder or something else,try to get them on the internet..    i don't think cookies have something to do ..
