By cleaning DLL file that is not longer used by memory, computer can perform faster. So, how is the way to do this? Before I reveal the tricks, I’d like to explain a little bit about DLL file.

Windows has one “library” named Dynamic Link Library that we used called DLL. For specified purposes, usually this library is temporally placed in memory so processor just need to access memory to execute specified programs, not necessary move back and forth to harddisk that performance slower than memory. But, in some cases, DLL file that retains in memory is not erased although not even ones use it.

This cause memory wasted. If memory in computer limited, let say just 64MB, computer will going slowly. The way to overcome this problem is cleaning DLL file that is not used anymore. In order to that point, I suggests following tricks, the steps are :

1. Execute Registry Editor, I hope you are not forget the way to do this.
2. Enter to subkey My Computer\HKEY_LOCAL_MACHINE\Sofware\Microsoft\Windows\CurrentVersion\Explorer.
3. Click [Edit] > [New] > [Key] in Registry Editor window to create new subkey below Explorer key.
4. Named it with “AlwaysUnloadDLL”.
5. Click twice name [Default], then fill in the string value with 1.
6. Close Registry Editor, the restart your computer.
