This is the user shell, which we see as the familiar taskbar, desktop, and other user interface features. This process isn't as vital to the running of Windows as you might expect, and can be stopped (and restarted) from Task Manager, usually with no negative side effects on other applications
coincidence then that the usage of the line you underlined is the reverse the usage of chrome.exe (2nd line down) in network activity? I suspect the usage was chrome all along, though I don't know what its doing exactly
chrome (line 2) mirrors Explorer (line 3) of Network usage. Chrome sent 262, explorer received the exact same amount. Chrome received 34, explorer sent that amount.
but we talking bytes here, its not a lot. It shouldn't slow youtube down at all.
I told you it wasn't a virus in my 1st reply, i said it was the desktop.
I should have mentioned it was just lan activity but it was 7am here and I should have been asleep.
The amount of data being discussed isn't really going to be your problem. 296 bytes, not megabytes or gigabytes... that is literally the amount used by 296 letters in a text document, Its nothing, you have wasted more just writing this thread trying to fix it.
If YouTube is giving you problems, the 296 isn't going to be the cause. You chasing the wrong thing.
