10 Tips on How to Properly Maintain Your Computer

Steps that I did not notice on the guide include:

Running a scan disc before doing a defrag

Using Microsoft Security Essentials and Malwarebytes.

Making System Restore points, at least once a week

Makaing a system Image once a month (varies by user)

Not relying on your A/V common sense, should prevail. You know of many sites can cause a problem.

Do not use any reg cleaning or optimizing software.

Download and use Ccleaner about once every two months. Untick any registry entries.
Piriform - Download CCleaner, Defraggler, Recuva, Speccy - Millions of users worldwide!

If you follow these instructions, you will be trouble free for a long time to come.

Be sure to back up your hard drive about once a month (varies by user) and to keeep system restore points up to date.

I have not used MS Security Essential for a while, and am not familiar with many of them on your list.

first of all,
In advanced settings, i saw "create system restore point."
What is this?

System Restore is one of the best features of Seven.
If you have a problem you can go back in time with System Restore and everything will be just like it was then. It is a picuture of your Operating System and does not affect your personal stuff.

Holy moly, I'd die if my hard drive was 10 percent fragmented!

How Often Should You Defrag?

hummm......

and what is next one in the list "making system image"?

Still, but I do use my compulator all day everyday. In fact, early this month was the first time this year I've had it off for two nights in a row. I defrag every Saturday, but I don't use the Windows defragger, I use Ultimate Defrag. It even says so in the name, it's ultimate.

It looks like besides updating a BIOS recently, reloading my OS helped cure potential problems I may have had with conflicts about which Win files got updated in order; The System Readiness Tool had a pop up during the updates after restoring & seemed to cure those problems that may have occurred, but one of the 7 Forums awhile back had one of the facilitators talking about advanced ways to use stuff like SysTool, possibly going on to use a Reg Defragger that appears to be Windows 7 recommended. Unfortunately it sounds like the oversold ad I've heard and seen for PC cleaner, but I downloaded in case I think it might be useful in a crisis. I also have shortcuts in the desktop and taskbar for task manager, checkdisk and etcetera, and feel better about some of the things that can happen in a hurry these days. I could use more opinions about registry maintenance, though, because I see so many posts wherein registry entries supposedly start to have more potential for getting corrupted. I have stayed close to manufacturers hardware updates & software updates, and try not to use any outside apps, but I have experienced what seems like a little improvement with the third party stuff at times.

For most applications, Windows 7 built-in defrag is good enough. Just schedule it to run periodically, and forget about it. Once you have a mostly defragged system, all of the performance gains are very small, beyond a point.

I would also second richc46, and stay away from the registry. Very little (if any) measurable gain in performance, and much risk of things going wrong.

Thank you for agreeing about the Registry. I prefer not to engage in lengthy disagreements over subjective issues and was hoping that another would reinterate my position. That being said, I agree that the built in defrag is enough, but I and several others at this forum feel that one of the best is Auslogics; I and many others use it.
It is different, opinions, however that make a fourm a place to learn. Thank you for your opinion.
