Download speed throttled in window 10

Ever since I upgraded to windows 10 from windows 10 Home premium, my download speeds have been very low. My internet speed is 2.5MBps and after upgrading to Win10 the speed couldn't go over 500-600KBps, so I contacted MS support and the agent after 2 hours was able to fix it to some extent. He used cmd prompt window and used "scannow" command and then optimized my window somehow which improved the speed upto 1.5MBps and said to wait for windows update and it might fix this issue. I have waited over a week now and feel that there might be some answers in this community. Any help would be greatly appreciated.

PS. I'm connected via wifi and checking my speed from Other PCs running windows 7 is showing 2.5MBps as usual but not this one. It was okay in windows 7 when I was running it.
I have also deleted the windows.old folder so I can't revert back either nor would I like to.
