How to HanYuPinYin to input Traditional Chinese in Windows 10?
step 1: In Windows 10 , go to "settings"; "Time &" Language"; "Region & Language"; "Add a language"; "Chinese (Simplied)".
please note: the (Simplified) includes the Traditional words.
Step 2: under the "Language", select "中文（中华人民共和国）；Options； Keyboards；select Microsoft Pinyin；options。
Step 3：under Microsoft PinYin， selectCharacter sets， choose A character sets from (simplified Chinese) to (Traditional Chinese). The job is done!
Please note: Although you can use this method to input hanyupinyin and get the traditional Chinese characters, but if you need to switch to Simplified Chinese, you have to go to the step 3 again and change the Character Set from Traditional Chinese to the Simplified Chinese. I hope Microsoft or its developers can add some patch to fix it so that in the future, users can easily switch language from English or Chinese Traditional or Chinese Simplified modes.
Some other people suggested to use HongKong Traditional Chinese and bopomofo keyboard, but you can not select the candidite font （同音字）。I think Microsoft engineer may fix this bug in the future.
