dont worry about it. I have messed up my computer many, many times. just a week ago i had to reinstall my os, again, because i misunderstood one of skuzzy's posting. but i called that a teaching moment
.
U gotta start by always backing up your computer. create a system restore point that way u can always undo your changes.
do only one change at a time. then reboot and see what happens. that way if you mess up u only have to undo one thing.
uninstall all those programs/games that you downloaded and your not using anymore.
I use iobit's advance care system. its free and there's an utility called start-up manager in the administrator tools. I managed to bring down my processes from 52 to 33 using it. there's a lot of junk that loads that you dont need but u need to figure out what it is first. again. do one change at a time then reboot. just do a couple of changes a day. that's way u wont get bored.
And then again if you are like me, you'll have to reinstall windows several times. but everytime u do you learn something new.
