Steps to reproduce the problem:
1. Open Chrome/new tabs/new window
2. 
3. 

What is the expected behavior?
Background processes shouldn't stay open like this even after killing chrome.

What went wrong?
In the attached image, I can scroll down for 4 pages or so. I just open Chrome, and I think every time I open a new tab or window something processes slowly begin to accumulate. I have attached the command line in other comments below: every chrome are all of this format, with some codes at the end that vary slightly. These are all in background processes, and is unrelated to my extensions, none of which affect the outcome after having tested that disabling them does not change anything (PixivKit, Tampermonkey, uBlock Origin, and Viramate).

I have disabled background processes, so this is unrelated to that function.

I don't know how this started, but one day I opened up task manager when my computer started getting a bit slower and then I noticed this strange occurrence. Also, I believe that it has began to cause Chrome crashes if enough processes open up after a while, which may be related to even just opening up new tabs.

Did this work before? N/A 

Chrome version: 63.0.3239.132  Channel: stable
OS Version: 10.0
Flash Version: 

The command line is

"C:\Program Files (x86)\Google\Chrome\Application\chrome.exe" --type=crashpad-handler "--user-data-dir=C:\Users\***\AppData\Local\Google\Chrome\User Data" /prefetch:7 --monitor-self-annotation=ptype=crashpad-handler "--database=C:\Users\***\AppData\Local\Google\Chrome\User Data\Crashpad" "--metrics-dir=C:\Users\***\AppData\Local\Google\Chrome\User Data" --url=https://clients2.google.com/cr/report --annotation=channel= --annotation=plat=Win64 --annotation=prod=Chrome --annotation=ver=63.0.3239.132 --initial-client-data=0x1d4,0x1d8,0x1dc,0x1d0,0x1e0,0x7ffa33825720,0x7ffa33825760,0x7ffa33825738

All the processes most likely share this format. I checked a random assortment of the several background processes and they were all like that with some minor changes at the end.
