Force Windows to Unload DLLs from Memory to Increase PC Performance
You can increase PC performance by forcing Windows to Unload DLLs from Memory. Windows Explorer caches DLLs (Dynamic-Link Libraries) in memory for a period of time after the application using them has been closed. This can be an inefficient use of memory on low memory systems, and may cause problems or delays for programmers developing with Windows DLL files. Using following method you can force Windows to unload DLLs from memory to free some more system resources.
Open your registry and find the key
Create a new sub-key named ‘AlwaysUnloadDLL’ and set the default value to equal ‘1’ to disable Windows caching the DLL in memory.
Restart Windows for the change to take effect.
System Key: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\AlwaysUnloadDLL]
Value Name: Default
Data Type: REG_SZ (String Value)
Value Data: (1 = enable)
