Roommate's Laptop Using Too Much Bandwidth

I have a new roommate who just moved in and her HP laptop, running Windows 8.1, is consuming all the bandwidth in the house. When her laptop is off or the wireless is disabled, every other device in the house is fine (desktop, two iPads, Xbox360/PS3/Wii-U, five phones). Even with every device connected and people streaming, my desktop still shows a connection of around 25 Mb/s (Comcast). When her laptop connects, even on idle, with no browser open, it drops to around .5 Mb/s or so.

I've looked at Comcast's usage report on the bill and we went from around 25GB/mo to about 450GB/mo as soon as she moved in.

I've combed through the site to find an answer, but everyone's answers seem dismissive of people's complaints. Here's what I've tried so far:

1) I got a new router because someone suggested that might be the problem. It wasn't.

2) I got a new cable modem because it came with the router. It also didn't fix the problem.

3) Fiddled with QoS on the router and set my desktop to high priority and hers to low priority. It didn't fix the problem.

4) Turned on Win 8.1 metered connection settings and made sure that metering was turned on for just about everything I could find including Bing searches, back-up utilities, etc. (She doesn't have Onedrive enabled/running)

5) Made sure Windows Defender is on and ran a scan. The machine is clean.

6) Double-checked to see she isn't running a torrenting client. She's not. (She's completely technologically illiterate; when I first asked her about the problem and asked if she was torrenting/downloading, she had no idea what I was talking about. Her confusion led her to ask if her having a wireless printer could be the problem...)

7) Ensured her wireless adapter's drivers were up to date and that her laptop is using the default Windows configuration tools and not something third-party to manage the connection.

I'm completely out of ideas, guys... I don't know jack about Win 8 and I can't figure out anything else to try.

Just open the resource monitor on the PC and look at the network section. It should show each process and how much each is using where it is going.

If you still can't tell use wireshark and capture all the data the machine is sending and receiving.

Thanks, but see point 5. One of the first things I did was run a virus scan to see if that was the problem, but it appears to be clean. :\ Microsoft Security Essentials (Windows Defender on Win 8) seems to think the machine is virus free.
 
Hi

Since problem is extra download rather than uploads it is less likely to be sending out massive amounts of spam

Is the laptop downloading TV episodes using some sort of TV recorder
This would not be detected by av software
You should be using at least 2 different anti spyware apps if you are using only Microsoft or any free av software

Internet security would be more effective, integrating av , anti spyware & firewall software

If the amount of bandwith used is troubling you could always limit the amount she can use in a month, but that wouldn't fix the problem and will most likely just make her angry.
 
Where I work we had a lady that had an application on her laptop that downloaded movies and things in the background. She did not realize it was even doing it. It would max out our internet line every time she connected. It seems like it was some type of Kindle Fire app she had on the computer.

I appreciate all of the suggestions, everyone! I'll take a look again to see if I can find any of these, but I did previously try to find programs and it didn't look like any were running. I checked the task manager.

I'll update y'all as soon as I look into these (when I get home from work), but keep the suggestions flowing!
