I recently also used IE10, but feel the speed of opening the Web page slow, sometimes open the page need 10+ seconds, even open baidu.com also slow.
It's a tangle?
To query some information, groping for a moment, found that the IE10 enabled the protection mode, promoted the so-called security level and lead to!
In fact, this so-called "Enable protection mode" does not have a great effect, to the system security, or to rely on security and other professional software!
As shown above, turn on the IE10 setting option-------security-------Remove the "tick" selection in front of "Enable protection mode"-------application--------OK, after the reboot, the speed of opening the IE10 is fast!!!
