Good news, and about time too, but with Office 2019 perpetual licence no longer being able to edit files, is this completely stuffing up the entire suite, or removing the ability to edit files from within OneDrive? Sounds stupid to have a kill switch like that, and they could totally fine a way to update the certificate if that's the reason behind it..
Hmmm i don't think they do as such, and centralizing and making them recurrent was the point, because they are scattered randomly in time and from several different channels.
The post-installation disk footprint hasn't changed much. In version 0.99.1, it was 979 MB. Now, it is 959 MB. That's just 2%. Also, PowerToys fills the disk with logs like crazy. Just look inside "\AppData\Local\Microsoft\PowerToys".
