We can tweak the windows 7 manual to accord ourself  custom.There are sevral samples .

Change the Power Plan To Maximum Performance

The Power settings in Windows 7 is not automatically set for maximum performance. By default the power plan in Windows 7 is set for a balanced performance with energy consumption on hardware. So you may not get the optimal performance from windows 7 if this is the case. So we need to change the power plan to High Performance Mode.

 1.Double click the Power Options in the Control panel.
 2.Click the down arrow showing Show Additional Plans to see the High Performance power plan.
 3.Now just activate the High Performance plan and that's it.
 4.Go for the advanced power settings.
 5.Go to Hard disk, then to Turn off hard disk after and set it to Never. This enables the GC to do its job while logged off.

2.Now type "msconfig" in there and press Enter Key to open up the System Configuration Window.

Turn off Unused Windows 7 Features

There are many feature in windows 7 that we often don't use.
Disabling these unused features in Windows 7 will really help in speeding things up.

1.Open up Programs and Features from Control Panel.
2.Click the Turn Windows features on or off from the left pane.
3.Now uncheck all the Feature that you don't use in Windows 7 [e.g. "Games"] and restart the system for the changes to take effect.

Speed up the Menu Show Delay Time

This will show you how to change the amount of time it takes for a menu in Windows 7 to pop, fade, or slide open when you run the mouse pointer over it.

1.Take the RUN option from the start menu or press [Win] + R
2.Now type "regedit" there and press Enter Key to open up the Registry Editor Window.
3.In regedit go to HKEY_CURRENT_USER\Control Panel\Desktop
4.In the right pane, right click on MenuShowDelay and click on Modify
5.Type in a number between 0 to 4000 [400 is default, I use 1] for how many milliseconds you want the Menu to wait before it opens
If you use an entry of 0, there is no menu display delay. However it is not recommended to use 0 though since the menus may be hard to navigate through at that speed.
