DLLs (Dynamic Link Library – Dynamic Link Library) are parts of a software load in Windows memory as required. This mechanism is supposed to optimize the use of memory, the DLL is loaded but also unloaded as and when situations. In reality, when you quit an application, Windows sometimes keeps some DLLs in memory, which reduces the performance of the PC. To force the system to eliminate DLL memory when no longer used, modify the registry.

Run Regedit and open the hive HKEY_LOCAL_MACHINE.

Open the HKEY_LOCAL_MACHINE / SOFTWARE / Microsoft / Windows / CurrentVersion / Explorer.

Create value (Edit, New, DWORD Value and then right click to rename) AlwaysUnloadDll. Give it to 1.

Once Regedit closed and the computer restarts, you should see a performance gain.
