You don't actually want to REMOVE them from the computer you want to stop them from running at Start up. To do this the easiest way is to use a Free program like CodeStuff Starter
Now when the program opens you will see three tabs:
Start ups, Processes (which is like Task Manager but gives more info), and Services.
Begin by clicking Start Ups
Take the check mark OUT of these:
AGRSMMSG
ATIModeChange
HP Software Update
HP Component Manager
ctfmon.exe
Next move to Services Tab:
Double click on each one of these. When it opens first Stop the service at the bottom of the box. Then go to Start Up Type and change Automatic to Manual. Do that with These:
Ati HotKey Poller.
InstallDriver Table Manager (IDriverT)
IviRegMgr - InterVideo
Close the program and reboot the computer.
The ones I haven't mentioned then leave alone. A couple have to do with your printer and for some reason if you get to fooling with printer files you end up having trouble with them.
You CAN also try this with those various LANDesk entries and see if the computer runs ok and goes online ok. If it does then leave them off. If it doesn't work ok then go back into CodeStuff and turn them back on at the next boot up and reboot.
