Your trusted windows OS for your PC is stealing 20% of your net connection!
All that for just updates! Here's how to get it back.
The first thing you have to do is go to the start menu. Then use
"RUN" and type in gpedit.msc. On the left side of gpedit you will
see computer configurations. And under it you'll see Administrative
Templet's, click it. Now under that there should be more folders. Click
on the Network one. Now click the Quos folder.
In the main part of the window on the right look for the option
"Limit reservable bandwidth". Turn the feature on. By clicking the
properties box you will now enable this and change the amount from
20% to 0% or if you want to be able to reserve a little bandwidth for
the updates set it to 2 or 5%. Even if it says its not enabled it is.
Restart your computer and the change should take effect.
If you don't believe this run a speed test on you internet. When I
first did this it was at 4000KB/s which shocked me that really slow
for cable modems. After I put the reserved bandwidth to 0% i was able
to get it to a shocking 14000KB/s but its usually about 10000 which is
still good. Anyway hope you do it right and your system should be running the way it was meant to be.
