DLL files and slow computer

Imagine this. You are working in MSWord, close it, that work some in Dreamveawer and Photoshop, close both and than you turn on Winamp to listen some music and start surfing the Internet. All named programs have some DLL files loaded in your RAM until you turn of the computer. And working on computer will be slower and slower. To change that, and to make that DLL files unload after closing particular software, do next:

HKEY_LOCAL_MACHINE/Software/Microsoft/ Windows/CurrentVersion/Explorer

Make new STRING Value, name it AlwaysUnloadDll and give value 1 to it.

Than just restart your Windows.

BAD IDEA, WILL IMPAIR PERFORMANCE.

The author is displaying ignorance of how caching works in Windows. Windows retains program code, application data, and DLL's in memory after the application closes. This behavior is known as caching and it has a long and distinguished history in computer systems. Windows will always try to find some use for as much memory as possible in order to improve performance. Unused memory is wasted memory.

The Windows cache is dynamic. Windows has a complex and efficient system for reclaiming memory from cache when it is needed for other purposes. Nothing is ever locked in the cache. Premature freeing of cache memory serves no useful purpose and will almost invariably impair performance.

Windows designers know more about memory management than you do. Windows will perform best without amateurish tinkering.

The registry setting mentioned was intended for the use of software developers, not as a means of improving performance.
