This tutorial will really help you lot.. i think so if this already exist... mods can delete it

If you want your computer to load faster on startups I really recommend you to clean your desktop. If you have many icons and stuff on your desktops it takes much longer to load than if you only have a few things.
So my tip to you is to clean off nearly every icon. It doesn't take much longer to go to the start menu and find the program you want to use.
As well as if you have folder and files on your desktop. Put them somewhere else.

.%temp%

The %temp% is not hard at all to clean and in some cases it can make your computer faster.
Here is how you clean it:
Go to Start > Run and then you type %temp% and hit the enter button.
A new window will pop-up, in that window delete everything and then close it.
If you can't delete everything just leave it then.


Disk Defrag

If you want your harddrives to go faster then I recommend you to disk defrag.Windows already have a disk defrager but I recommend you to use Auslogics Disk Defrager.


Uninstall Programs Correctly

Many people use Windows Remove and add programs, but the bad thing about it is that It doesn't delete the registry files after you uninstalled a program. This could accually make your computer a little slower so how can you delete the registry files?
The answer is very easy. It's a tool called revo uninstaller wich cleanes up everything after you uninstalled a program and it uninstalles programs aswell for you.


Startups

If you want your computer to go faster on startup you can clear your startup programs. What you do is simple. You just tell the program to not start att the startup. And how to do it is also simple:
Go to Start > Run and type msconfig and hit the enter key.
Go to Startup and clear the programs you don't want to start when your windows starts.
If you don't know if you need the program to start up or not you can check it out here, aswell as you can check if there is a trojan or any other unwanted stuff that startup.
