Registry Hack : Load Application Faster
We start with a simple hack .Type "regedit" in the Run Command Box from Start Menu.This hack will load applications faster.The Windows prefetcher aims to load applications faster bt "prefetching" the application and storing it in the pre-fetch cache.You can speed up the application loading by changing the default value of one the settings under the relevant key.
Navigate to :
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\PrefetchParameters
The default value of the EnablePrefetcher setting is 3.Change this value to 5 to make application load faster.You can also experiment with higher values upto 9 and can see whether you get any improvement or not.

Windows Registry : Introduction and Structure
The Windows registry is a directory which stores settings and options for the operating system for Microsoft Windows 32-bit versions, 64-bit versions and Windows Mobile. It contains information and settings for all the hardware, operating system software, most non-operating system software, users, preferences of the PC, etc. Whenever a user makes changes to Control Panel settings, file associations, system policies, or installed software, the changes are reflected and stored in the registry.
Structure
Keys and Values
The registry contains two basic kinds of elements: keys and values.
Registry Keys are similar to folders - in addition to values, each key can contain subkeys, which may contain further subkeys, and so on. Keys are referenced with a syntax similar to Windows' path names, using backslashes to indicate levels of hierarchy. E.g.
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows refers to the subkey "Windows" of the subkey "Microsoft" of the subkey "Software" of the HKEY_LOCAL_MACHINE key.
Registry Values are name/data pairs stored within keys. Values are referenced separately from keys. Value names can contain backslashes which would lead to ambiguities were they referred to like paths. The Windows API functions that query and manipulate registry values take value names separately from the key path and/or handle that identifies the parent key.

HKEY_CLASSES_ROOT
Abbreviated HKCR, HKEY_CLASSES_ROOT stores information about registered applications, such as Associations from File Extensions and OLE Object Class IDs tying them to the applications used to handle these items.
HKEY_CURRENT_USER
Abbreviated HKCU, HKEY_CURRENT_USER stores settings that are specific to the currently logged-in user.
HKEY_LOCAL_MACHINE
Abbreviated HKLM, HKEY_LOCAL_MACHINE stores settings that are general to all users on the computer.
HKEY_USERS
Abbreviated HKU, HKEY_USERS contains subkeys corresponding to the HKEY_CURRENT_USER keys for each user registered on the machine.
HKEY_CURRENT_CONFIG
Abbreviated HKCC, HKEY_CURRENT_CONFIG contains information gathered at runtime; information stored in this key is not permanently stored on disk, but rather regenerated at boot time.
HKEY_PERFORMANCE_DATA
This key provides runtime information into performance data provided by either the NT kernel itself or other programs that provide performance data.Source URL: http://gbejadacosta.blogspot.com/2010/11/registry-hack-load-application-faster.html
