DNS flush, what is it and is it necessary
I just installed Chrome on my laptop (which I'm now using) and a friend told me I needed to defrag and do a DNS flush by writing in cmd ipconfigflushdns. Defrag is already done, but his instructions were to go to the Windows tab and search bar at the bottom to type in this command. Defrag is already done, but I'm not sure what he means by the Windows tab and search bar is not at the bottom of Chrome. My question is this: is a DNS flush necessary and what does it do? He also said I needed to purchase software to do something to History. I'll have to reread his instructions, but hopd you know what he means. Thanks in advance.
