No cortana (warning: no start menu searching either), no modern apps (you can intergrate calc.exe), no store, defender, remove alot of telemetry, one drive, etc.
At some point you have to trust something, whether it be your software or your hardware.
Besides the telemetry stuff, it's not a trust issue. I just don't have a need for any of the packages I remove. I don't need cortana and search, I don't need Windows Defender and it's cloud features, I don't need onedrive, xbox, modern apps, etc. It's my choice, so I remove them.

There are issues such as no more start menu search because of removing cortana. It's all about what you personally need.
Thanks, but it's just a throwaway user name I won't use after this post.
