Windows 10: Weird devices, high upload usage, slow internet speeds

Version: 1909

So for the past few weeks I've had a bunch of weird problems.

1. My data upload usage went through the roof (16 gigs!) on a day I am certain no device on the network was conceivably uploading anything
2. My internet speeds on this PC in particular are often 1/10th what they should be
3. As soon as I power on the PC, Bluetooth turns itself on and makes the PC discoverable, something called a "Bluetooth USB Module" enables itself, a "Bluetooth (Personal Area Network)" device connects itself (shown paired simply as "Device" under PC Settings), and multiple "Microsoft Wi-Fi Direct Virtual Adapter"devices (sometimes numbered between #1-9) show up as hidden devices in Device Manager
4. Even when the PC is idle there are constantly dozens of Service Host tasks running 24/7, and "NetworkService -p" is constantly sending/receiving data to several multicast IPs
5. In Services, there are several services enabled with underscores and letters/numbers after them, a lot of them seeming to deal with things like connected devices and internet connection sharing

One other weird occurrence was that, a few days ago when watching the YouTube app on PS4, a laptop on the network which has never once cast to/from or logged with the associated YouTube account (and vice versa) showed up in the bottom corner of the screen as having "signed on," despite the fact that no one was using it at the time.

Does any of this sound like...anything?

Brevity can be a virtue but it can also be counter-productive.

• Which application demands excessive CPU resources?
• What would you like to ask?

 

slow internet speed through ethernet(high speed internet connection), and disk usage as high as 100 percent

i have an ethernet connection for using internet. i have 2 windows 10 , version 1607 laptops. When i plug the ethernet cable in one laptop, i can use internet at the speed promised by my service provider(2mbps). I have checked this speed in task manager.

but when i plug in the same ethernet cable in other laptop, internet speed in task manager shows very little speed near about 50 kbps. and this too doesnt remain constant. the speed varies very rapidly between 0-100 kbps. suppose first i saw 20kbps, then
in next second it goes as high as 100 kbps..and then in the next second it shows 0kbps..remains 0kbps for a few seconds, and then again speed picks up for a few seconds.

One more key observation, whenever internet speed grows, my disk usage grows as high as 100 percent. And then internet speed slows down.

Whenever i connect this laptop(the one i am using ) to internet either through ethernet/wifi...even with higher speed connection, though i get a bit higher speed, but i have observed a lot of fluctuations in speed in task-manager, performance tab, the graph
rarely stays straight(constant), it just forms a triangular shape, it as if a connection loss is taking place every 4-5 seconds.

A month ago, this PC was working well.
