OK cool, but if you disable the BITS service, I suppose this method doesn't work. Of course, the status of services should also be monitored, because otherwise malware can simply enable/disable certain services.
If you disable BITS on Win 10, you're going to bork a lot of stuff. Win Updates and other Microsoft processes use it to speed up downloads. Also some app software like AV software also use it for their downloads.
Yes correct, but I don't often update Windows and avoid using AV's. But most people should indeed not disable this service.
