Answer 1

This is for Chinese user only. This is because of the Sogou Pinyin (搜狗输入法）occupy this shortcut system wide. And it won't release if you just uninstall it.

Go to here to disable it: Language->Advanced settings->Change language bar hot keys

Uninstall it is not working, you need disable that setting then uninstall it.
