Manual means that the process starts when, say you launch a program, it means that it doesn't automatically start when you start your computer.
Disable... stops it cold, won't launch.
Please correct me group if I am wrong.
Yes there a bunch of "things" in the Systems on your computer... that's just the way it is, your not doing anything different on a basic level than anybody else.. no worries.
You are just going to have to route out the ones that are system hogs as in the url that I mentioned, those are the ones that get added when you installed new devices, or progams.
As mentioned by another person you can go to run--> msconfig and then see your start ups that may be slowing down your computer.. I use this free program
[windowsstartup.com...] it shows and explains things a bit more than msconfig.
For example... when ever you install a new device or maybe a program, use task manager, and or the above program, to see whats running or got place into "startup"... then G--gle it... for example, I installed a sound card... it came with all kinds of stuff.. and on investigation half of the stuff that it loaded I didn't need.. and one app had a known memory leak.
What you do whenever you have an app that you want to know what it is doing... just G--gle it.. you will find a bunch of "helper" websites that are set up specificly to investigate and evaluate every app know to mankind. You'll get the hang of it.
You can also use your task manager to see all the muck running.
I prefer this free task manager program
from the guys that put out a rootkit evaluation program...
which you should also download and just check your computer for a rootkit once in a while.
I hope I haven't violated any forum rules posting those links...
Unfortunately I am quite a bit of a novice so I can't answer about the touchpad.. but g--gle the apps and you will find if it's junk or need to have. Sorry I took so long to check the forum and respond... I didn't anticipate your questions.
p.s. you first started this question with now your computer is running slower and IE crashes.. Personally.. I think you should be running Firefox.. many would agree. Also... I know my desktop computer gets dirty as Pig Pen in Charlie Brown.. and I'm cleaning out that puppy every three months. For my new laptop that I purchase recently, I bought a cooling fan deck that it sits on, and I went to the hardware store and bought a furnace filter, cut it out of the cardboard case and down to size of the bottom of the laptop between the cooling deck fan and the laptop. I don't travel with the laptop much at all so this is practical for me, especially as I know how dusty my destop gets. My laptop is really a "desktop" laptop.. 17 inch screen, full keypad, etc... What I am saying here is that an over heating motherboard (processor chip) will slow down the computer and Crash it.. and dirt and dust will cause the overheating. I've never cracked open a laptop... but I'd imagine it's no different.
