Here is one of the not so known method for free-up the RAM to make the Windows run faster.

When programs run in Windows XP, they frequently use what are called DLLs (Dynamic-Link Libraries).

These contain shared programming instructions and other files like icons, graphics, sounds, etc. that ifferent applications use in order to run. DLLs are stored in RAM whenever the applications load them; when ou quit a program, XP is supposed to release the DLL from memory. But some DLLs can get stuck.

Here is the method to mend this up.

Step 1: You can force Windows XP to release DLLs by adding a Registry key.
Step 2: Select Start > Run >Enter regedit >Hit Ok
Step 3: This will open the Registry Editor and navigate to
My Computer -> HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows -> CurrentVersion -> Explorer.
Step 4: Right click on EXPLORER in the Left Pane, Select New > Key.
Step 5: Name it as AlwaysUnloadDLL and double click & set the default value to 1.
Step 6: Restart Windows to activate the change.
