Windows 10: Download speeds not meeting actual internet bandwidth

Hi,I am currently experiencing issues with download speeds on my desktop. Internet speeds have been a problem for quite some time now, and I figured it was due to my PC being connected via WI-FI.

The weirdest part of it all is that I have no issues with upload speeds, as they are actually over what I am subscribed to.

Windows 10 uses high internet bandwidth

After installing windows 10, I see decrease in internet speed. I am aware that it uses lots of graphics. But still it is high. Any steps to reduce the bandwidth will be appreciated

 

Slow Download Speed

Prior to upgrade to Windows 10 my download speed was 70Mbps. After upgrade, averages 30Mbps. My son's laptop running win 8.1 gets the 70Mbps, my tablet gets the same. I have tried suggestions found on the internet,turning off automatic upgrades, changing
reserved bandwidth in Qs Packet Scheduler. Didn't help. Any suggestions??
