How to refuse Sogou browser to change IE default search

Using IE browser, set the default search is baidu, but recently searched for something, incredibly automatically turned to use Sogou to search, which makes me puzzled, I have not set the default Internet Explorer tool Ah, why is this?

After a study, found that this is the Sogou pinyin in the tricks, usually play the news window I also endure, did not think will automatically change the default search engine. Sogou Input Method added an address bar search function, this function is opened by default, as long as you use sogou pinyin to type, then will automatically jump to search Sogou, just to find in the advanced settings of Sogou Pinyin input method to unlock the Address bar search "function can be."

Uncheck this option

If you want to avoid other software changes to IE's default search engine, in the search provider settings in Manage Add-ins, check that the blocking program recommends changing the default search provider.

Disable changing the default search engine
