My Windows 10 had suddenly entries of three Chinese languages in the language bar, without me having them installed.
They are not present in the keyboard layout, so I cannot uninstall them.
However, this may just be a side effect of other system options because in the MS Word language options, Chinese does not appear.
I have seen this and this old thread but I am not able to translate the suggested solutions into a Win10 environment. I was neither able to locate the mentioned registry keys nor the
Office 2010 installed IMEs in the corresponding Microsoft Word 365 environment.
I installed Chinese/Taiwan as a language option via
Windows display language - it appeared as a fourth Chinese language entry in the language bar, so uninstalling it afterward, did not solve the problem.
This thread was marked as a duplicate, alas it is not. The first method of the supposed duplicate answer does not work, as I explained because the Chinese languages are not listed as language options.
The second method looked promising. Indeed, under
HKEY_CURRENT_USER\Keyboard Layout\Preload (but not in the other three mentioned registries) were three Chinese keyboard codes listed. I deleted them and restarted. The Chinese keys are now deleted...
While scrutinizing the options in Setting, I noticed that the languages are also mentioned under advanced keyboard settings but you can only change here their hotkeys.
