If you're using #Microsoft #OneNote, you will face disadvantages when you don't switch to #Windows11 soon:
You are forced to "One Note on Windows" which requires a #Microsoft365 account. If you want to keep your previous computer/OS, your synchronization speed gets reduced just to punish your disobedience: https://www.windowslatest.com/2025/03/24/microsoft-will-intentionally-slow-onenote-for-windows-10-so-you-ditch-it-faster/
For anything that requires a certain amount of privacy/security, for anything long-term (avoiding #lockin effects), OneNote was a bad idea in the first place.
People who started with the original OneNote already faced data loss when MS forced them into the then mediocre cloud version in 2018: https://karl-voit.at/2018/04/21/end-of-OneNote/
My recommendation: re-evaluate your requirements and switch to a much better long-term alternative, such as #Emacs #Orgmode & not yet another hip lock-in monster like #Obsidian, #Evernote or other closed source #cloud solutions: https://karl-voit.at/2021/01/18/tool-choices/
