I have a Compaq laptop from windows XP and I’m not sure how to delete things permanently from my PC. If I go to Start, All Programs, Accessories, System Tools and Disk Cleanup then I cleanup C Disk, does it take it off permanently? I’m kind of iffy about going to websites and downloading things to erase things, because it ends up getting half way there and you have to pay for it. So I’m just wondering about the Disk Cleanup, And also if your a great computer Wiz what does a disk defragmenter do?

My husband and I don’t have a home phone because we have cellphones. We do have cable though and I am curious if I should get the computer hooked up through my cable(would this still require a phone?) or should I go with wireless internet? How much is wireless, how do I have it installed, and what accessories do I need? Any help would be greatly appreciated. While I know how to work a computer, I certainly am not a computer wiz. Thanks!
