I have three programs that are supposed to run on startup - an encryption program, Skype, and a backup utility. All are set to run on startup using their internal settings, which I guess means thy run from Registry settings. They are all shown as Enabled in the Start-up tab of Task Manager. Apparently randomly, they fail to start perhaps 40% of the time when Windows starts, and I have to run them manually. They all run or none does. It seems to go in waves, with the problem seeming to go away for a while then returning. I am running Windows 8 on an HP desktop PC, and I have Norton 360 running (which starts with no problems). UAC is on. Fast Start-up is Off. There is nothing in my global or user Start-up folders other one script, which runs with no problems. Any suggestions gratefully received!
