At first, please note that this is not a duplicate question (to my best knowledge). I am not asking how to disable web search from with Cortana or the Windows 10 search bar, because there are a zillion tutorials about that. Instead, I have the following (somehow related) question:
A while ago, I have read somewhere that Windows 10 still transfers search terms to Microsoft / Bing, even if the web search is disabled in Windows search. That is, it was claimed that even after having followed the steps to disable web search as outlined here, it still transfers all search terms to Bing (for statistical analysis or other (more obscure) goals).
Since I am unsure whether I can trust the source and my memory, respectively, I'd like to ask if this is true. So my question is:
Does Windows 10 transfer search terms which are entered in the search box of the Windows Desktop to Bing / Microsoft even after you have disabled web search?
UPDATE: This question is not a duplicate
Since (as always) there seems to be a tendency to reflexively close this question, claiming it is a duplicate one, please note the following:
This question is not a duplicate to my best knowledge (and I did extensive research), especially not a duplicate of Can you completely disable Windows 10 sending data home?. Actually, it was me who wrote one of the answers to that other question.
Here, I explicitly do not ask how to prevent Windows from transferring data to Microsoft in general, which IMHO would be a silly idea anyways. Instead, my question is completely different and much more specific:
I would like to know if it is true that Windows Search transfers search terms to Microsoft or Bing, even if I have disabled the web search within Windows, and if is true, if there is a reasonable way to stop this (registry hack etc.). So this question is only and specifically about the secret transfer of search terms from the Windows Desktop Search to Bing despite web search being disabled in Windows.
