These contain shared programming instructions and other files like icons, graphics, sounds, etc. that different applications use in order to run. DLLs are stored in RAM whenever the applications load them; when you 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 set the default value to 1.

 

Step 6: Restart Windows to activate the change.
