I recently posed this comment in Feedback Hub, and I thought I would bring it up here as well. For the past week or so, I have had a persistent notification in Action Center that Runtime Broker is downloading pictures to my PC. Every time, I have clicked "cancel download", and it automatically resumes. Every time, I have gone into the OneDrive folder where the pictures are being downloaded and clicked "free up space", and it automatically resumes. I have hundreds of GBs of pictures intentionally left in the cloud and it seems that Runtime Broker wants them on my PC.
This is detrimental to productivity as I have no idea if storage space will be full when I need to save something. I cannot close OneDrive or pause syncing because I need to use OneDrive files for my job. This is a serious issue, in my opinion, and numerous people have been having this problem as I have seen from their other forum posts, but there is no real solution.
