I am following the general threads here and thought I would add my experiences. I have a W7 Home Premium desktop and a W8.1 that I bought in Australia. (US keyboard but that's OK) I am trying to set up a home network and have come into exactly the same problem with the error code 2147500037. I also hate IE and have used Firefox on everything for years. Still haven't worked out how to print to my HP printer though.
I also want to alert others to another cheeky MS download. I don't want to use a password of any kind to sign on to my computers that are used on a home network at HOME! A couple of months ago I found I was unable to enter my laptop because MS had downloaded a directive in one of their Optional Updates that now means I have to enter a password. Again - I know there is a work around by opening another account but it shouldn't be up to me to do a workaround. Who are you MS to direct me to use my computer as you think I should? You have given me software for me to download and that I trusted (secretly) that could be described as malicious. We abhor all malicious software so why did you MS do this? Your answer will be interesting.
Here's an intriguing answer: I'm going to go out on a limb here and say that they didn't do that. Your blame is misplaced. Networking without a password? More like a cached password you saved last year expired or was deleted. They won't ever dignify you with a response to these accusations by the way. This is a mostly user-to-user forum.
