I uninstalled every single network adapter in device manager, restarted, connected to wifi, reinstalled wifi card drivers, installed cfosspeed and then uninstalled cfosspeed again, then it correctly uninstalled, removing it's driver and everything worked very smoothly after this, I was finally able to reach the same internet speeds I was seeing on my smartphone and macbook.Īlso if you play over wifi, you should run the tcpoptimizer tool and read about disabling nagle's algorythm using tcpoptimizer. To do so, a simple uninstall of cfosspeed wasn't enough since I had multiple kinds of network adapters (due to my virtual machines) and it wasn't able to delete it's own adapter correctly. I just don't trust it anymore, I've noticed huge gains after finally successfuly uninstalling it completly. I uninstalled it tonight after discovering it was responsible of my wifi upload speed issues I have been having for the past few years.

When I uninstall and restart it re-appears. (spd.exe) Recently I've noticed CForSpeed running on my PC, Does anyone know where this comes from or what it does I think it might be being installed by some gaming component driver. Sorry to necro this but I used to be a licensed user of cfosspeed that I paid once nearly 2 decades ago. What is cForSpeed Service and why is it Mysteriously running on my PC, Reinstalls itself.
