I'm writing from home so I only have a pair of W10 laptops but both didn't have such an issue. These laptops had the stock W7 issued by their makers which I uninstalled any Antivirus to help avoid any conflicts prior to the W10 Microsoft upgrade.
Tell more.
Prior to upgrade to Windows 10 my download speed was 70Mbps. Now it averages 29Mbps.Using the same network router My son's laptop running win 8.1 gets the 70Mbps, my tablet gets the same.
Any suggestions??
