Which of these optimized software is the best ?

I have searched a lot in the internet and i found these software were the most well-known software to optimized PC.
Tuneup Utilities
Advance system care pro
Window 7 Manager
Enhance my seven
Tweak 7
Glary Utilities free/pro

However i have tried tuneup but i see that sometimes it slow down my computer. So i don't know which soft is should used.
Any one have experienced about this problem? Can you give me the best software. Thanks a lot:)
My system info: Asus K56CM, Ram : 4gb, CPU i5 3317U, 1.7Ghz. Win 7 pro 64bit :

All those are almost identical and will do good to ur PC

Welcome to the Seven Forums

Windows 7 does not need any optimizing software. You will do more harm than good with any of them, then you will be back here asking questions why your computer is not working right.
Do not use any of them.

I personally wouldn't recommend ANY of them. Way too easy to mess things up with the so-called "optimizers". Windows 7 does a very good job optimizing itself. XP and Vista both could be benefited some by "optimizing" but imho at least Windows 7 does not need any 3rd party program to do what can be done in-house so to speak. Use ANY of those programs at your own risk!

Thanks. But after using for a time, what should i do to optimize my computer ?

Thanks a lot !

DON'T defrag your drive if it's an SSD. You will only put unnecessary wear on the drive. If you are not sure what kind of drive you have, you probably don't have an SSD.
