Win 8.1 Enterprise Edition IE11 often stops responding

Q: win8.1 Enterprise version IE11 often stop responding to the need to restart IE, including Microsoft's Web pages (such as this forum) open also often! This is too much trouble! Another anomaly, turn off IE open again, have been logged in the microblogging and forums such as the need to log in again (select the automatic login option)? seems to " AutoComplete feature does not work. There is also a poor compatibility of IE. Reset ie several times, invalid! win8.1 Professional version of the IE11, there is no such problem, this should be how to solve it?

A: About IE stop response may be caused by the add-in, try to use no load ie: in the run input Iexplore-extoff open without add-on ie. If no add-in is normal, it may be caused by an add-in. Manage Add-ins: Click the gear icon in the top right corner of IE to select "Manage Add-ins". Use the exclusion method to determine the problem add-in by disabling the add-in.

Q: As for the absence of response and re-entry, there is a little improvement. The reason is also strange: there is a forum when you are prompted to run a control that is incompatible with enhanced protection mode, "Windows Media Player extend" (as it is described), has been canceled, and this time it ran. As a result, the forum's automatic login incredibly good, and links to open the Forum link sometimes abnormal situation is also good. Even more fascinating is the discovery ie unresponsive situation also has some improvement, into the management add-in, see the installation control. Once again shut down IE, reopen, the forum can be used all the time! IE no response needs to restart the phenomenon is also less! But once again into the admin add-in, you don't see the install control!? (Note: Weibo still needs to be logged in again.) )

Inspired by this, temporarily shut down the enhanced protection mode, ie back to normal, microblogging and other forums can be automatically logged in.

The question is: is IE11 not automatically disabling incompatible plug-ins, and why is there no response? And why win8.1 Professional Edition does not have this phenomenon?

Running Iexplore-extoff, seems to have no obvious effect, if you turn off enhanced protection mode, you can still see the control enabled in the admin add-in with this command. It is better to turn off the enhanced protection mode directly.
