I removed FSDT KLAS, I delete the folders, I removed it in Addon Manager, I verified the SerialNumber key value is NULL and everytime I run the FSDT updater it installs a lot of KLAS files and creates the folder that it puts them in.
I have deleted the HKEY_CURRENT_USER\Software\FSDreamTeam\KLAS key. I don't know what else to do to stop this unnecessary action.
