Optimise Boot Files

Can reduce boot time to an extent because of defragmenting them at start up

Go to

HKEY_LOCAL_MACHINE\Software\Microsoft\Dfrg\BootOptimizefunction

Set the value of enable int this key to Y .
Reboot.

For application Stability

Can make each application more stable by launching in a separate process thread and also increases the load time

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl

Set the DWORD value for Win32PrioritySeperation to anything in 27,28,37,38.You can experiment with other values.
After doing this go to tools->view menu in the explorer and check 'launch folder window in a separate process'.
Reboot.

Values Used In The Registry

Do You Know About The Structure Of Registry?

It has a structure similar to the structure of the windows explorer where we have drives there we can create folders and then sub-folders in the folders and sub-folders may even contain some files or any other data, Similarly in registry we have six Hives which may contain keys,sub-keys ... so on and which in turn may have some values.

For Processes Stability

Xp runs all the 16 bit applications in a single process, run in individual processes to increase stability.

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WOW

Set the DefaultSeperateVDM string value to Yes.If its not there create it with the value Yes.

Fast Up Memory

This can be done by unloading unused dlls's which xp leaves in the memory after an application is closed, which cause a lot of problems.

Go to
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AlwaysUnloadDLL

If the Dword valuse AlwaysUnloadDLL is not there create it,if its there change the setting to 1.

Tricks (Can Be Applied At Ramdom) :-

1. Fast Up Memory

2. For Processes Stability

3. For Application Stability

4. Optimse Boot Files

Explanation :-

-> If any changes are made to the system by users,o.s,software,hardware, are all updated in the registry the changes can also be seen in the registry.

-> Using the registry only the computer starts at the time of startup windows uses the registry for the information about hardware,software,and other newly made changes.

-> Our system always maintains a backup copy of the registry with which it successfully started up last time so that it can use that information during startup failures.

-> Some of the information stored in the registry is restricted to a particular startup session.

-> Windows will make changes to the registry according to the situation and user preferences, for example when a user installs a software, windows will make the changes to registry either system-wide or user specific or in some cases both. It may also provide the user the option to choose from.

-> In some special cases registry is not available as in the case of boot process where boot.ini file is used for the process.

-> Usually the registry information is stored in c:\windows or c:\WinNT (in many files in \system 32\config folder).

-> Registry can be accessed by typing regedit.exe or regedit32.exe in run which in located at the start menu.
