As an I.T Professional I’m often asked to assist family members and friends with PC issues. Of course the skill level often differs and it is sometimes difficult to get accurate answers to questions such as OS, Browser version etc.
Point the person you are trying to help at www.supportdetails.com and they will see a page with info such as Operating System, Screen Resolution etc. This will be quicker than asking the person you are trying to help depending on their skill level of course. Would also be useful for seeing which public IP address your traffic is seen as coming from.
