Disclaimer: I am not a tech expert So I was browsing some of the surface help sites (including this one) because my surface was getting slow. I believe it was due to the humongous error reports it was generating. I also was exploring the reliability report and found many many instances where backgroundtaskhost.exe has stopped responding. I'm talking about a dozen times a day. What is this? Are these failures a consequence of a problem or the problem itself? Are there any known fixes? My surface is always fast for a couple days, then runs on four flat tires. I feel like I'm doing a lot of maintenance. I'd very much appreciate any suggestions..
