I don't think you have ever spent more than two seconds to read about what Pavan_N is talking about. This kind of answered me why for more than a decade the same bugs with Mircosoft Pinyin Input Method never get fixed.
At first, I thought that's because Chinese users not very good at English, so software engineers at Mircosoft didn't get the feedbacks. Apparently, the true reason is you don't even care AT ALL, for more than a decade.
Pavan_N is asking you about setting detail of MS pinyin, and you just copy and paste some **** about how to install MS pinyin.
I am so disappointed in you and your company.
The following configuration setting works for me getting a sticky ENG/CHINESE mode for Microsoft Pinyin input.
I added a Pinyin keyboard (may be it already was a default, if not, it is in Languages Options Add keyboard area).
Switch from ENG keyboard to Microsoft Pinyin keyboard, click the keyboard icon (which is labelled Touch Keyboard in the hoover balloon) (on the task bar); a virtual keyboard pops up, next to the space bar, there is an ENG/CHINESE toggle switch. Toggle it
to your preference. It seems to stick and survived switching from ENG keyboard to Pinyin keyboard back and forth.
By the way, this stickiness only applies within a particular application, e.g. notepad++, Word, Excel, PowerPoint etc. If you are switching language in the desktop, or inside a Google Search bar, etc., the default language becomes random, or elastic back
to ENG even if you tell it CHINESE is default.
The observation is, Pinyin keyboard behaves nicely in certain applications (Word, Excel) but it has a mind of its own in other applications.
Hope it helps.
