It's been working well for me. I have Killer AX1650 in a desktop and a notebook. On 4 of 5 drives in these 2 PCs the program was run on clean Windows 10 x64 installations including 2 Insider Preview builds as soon as Windows completed installing. 1-Run Disable Killer from Windows Update 2-Restart 3-connect to The Internet and run Windows Update. On the other drive it was a 4 step process. 1-Scan for and then remove Killer Software 2-Restart 3-Disable Killer from Windows Update 4-Restart No Killer software has been installed when using Windows Updated.Preview builds get updates on a weekly basis and no Killer software is installed or offered for installation.
