Boosting upload speed and improving Windows' TCP stack

Yeah, Windows 7's speeds with single connections are very, very slow. It took me years to figure out the reason were bad TCP settings, because it worked fine when I used a multiconnection downloader. What fixed it for me was running these 3 commands in a CMD with admin permissions:

    netsh interface tcp set heuristics disabled
    netsh int tcp set global autotuninglevel=normal
    netsh int tcp set global congestionprovider=ctcp

Thanks for the tips.

I tried, and the first two lines helped the speed bump to 2.5MB/s! The third one doesn't seem to have any immediate effect.

Still not OneDrive level, but I'm more than happy.

Good to know which actually take any effect, since it's been so long since I cobbled those commands together that I didn't really remember either!

I probably took them from Win7 forums or some stackoverflow spinoff, the TCP problems on Win7 are not entirely unknown.
