Only to find it had installed cFoSpeed again, even though Dragon Center was supposedly not even running-and not only did it reinstall it, but turned all LAN settings to 'on.' Turned off all settings except for Mystic Light, and uninstalled cFoSpeed yet again. I installed Dragon Center again, this time from the MS Store, because I read some people had better luck with it there. I should have just left it, but the rainbow bothered me just enough that I decided to try to change it again. That worked, and luckily I made a system image to commemorate the moment, but after I booted from a linux partition and back again, the GPU was back to the default rainbow lights. So, I uninstalled it again, along with Dragon Center, again with Revo. I used Revo uninstaller to uninstall cFoSpeed, only to discover it had reinstalled itself 5 minutes later. Quite by accident, when trying to figure out how to get Dragon Center to open again to change my GPU lights (the only MSI product I have is a 2080 Super trio), I discovered the culprit was 'cFoSpeed,' which was installed by Dragon Center. Since I built my new PC a few months ago, I've suffered from intermittently bad internet speeds (it would range from 60mb/s down to 8kbp/s randomly throughout the day).
