Question before changing primary Email alias and its effect on Windows 10

[HotCakeX]

If i change my primary alias for my Microsoft account, will I lose the synced personalizations and data in Windows 10?

currently my Windows 10 is connected to my primary outlook alias and all my Windows 10 personalizations, app data (sticky notes, to-do etc) are connected to that alias, but for some reason I want to change my primary alias to something else so before doing that I want to make sure all my data will stay intact and i won't lose anything (app data, personalization etc)

Thanks in advance

Okay I went ahead and tested this myself, on Windows 10 1909 and it worked.

I signed into fresh Windows 10 installation using my other, non-primary, Alias and I still got all of my personalization and data on Windows.
