Core memory unlocked... When I was ~10-12, I asked my dad (who knew nothing but thought he knew everything about computers) how to make programs for Windows because I couldn't in QBasic. His answer was "with C++!". He came home with a book Learn C++ In 24 Hours that had Turbo C++ on a single 3.5" floppy disk. Naturally, that did not work, but I still had fun failing to compile every program I attempted to write.

"Software I install" is a different metric than the "software that is part of the operating system itself".

Maybe I have the timeline wrong but here's at least a quick source to show I didn't just make it up (I question myself sometimes, joys of aging) https://www.nbcnews.com/news/all/u-s-says-chinese-telecom-gi...

Huawei has been under US export restriction since 2019 IIRC because they were violating US sanctions against Iran, which is why they could not continue licensing Windows, and I presume is why they went down the path to create their own desktop operating system.
