Hello @Gerard Schornagel ,
Thank you very much for taking the time to post this issue in Microsoft Q&A forum.
I do notice this issue and the similar feedback, kindly see this thread: Visual Studio BackgroundDownload.exe using all the system resources.
Not sure if you have tried to disable the task by following the steps which I mentioned in above thread, maybe this help to stop/reduce the running of BackgroundDownload.exe temporary.
I have tried to report this issue again. Would you mind also raising a new ticket on our Developer Community and directly reporting this issue to Visual Studio Product Team? If you do raise a new ticket, please share the ticket link here for better tracking.
Thank you again for helping us make Visual Studio better.
Wish you a wonderful day ahead!
Tianyu
