win7Computer speed is one of the most discussed topics here at Web Talk. There is no limit to the quantity of tricks to increase the performance of your PC. That’s why I decided to write another article on the subject. This time I want to share with you guys a nice hack which will force your Windows operating system to unload and delete all of its cached, unused and resource eating  DLL files (Dynamic-Link Libraries)  which slow your system down. 

  1. Click Start.
  2. In the Search box, type regedit and press Enter.
  3. Locate the following registry folder: HKEY_LOCAL_MACHINE \SOFTWARE\Microsoft\ Windows\CurrentVersion \Explorer
  4. Now, right-click on the right pane and from the menu, click New – DWORD.
  5. Name the DWORD AlwaysUnloadDLL and give set its value to 1 (one).
  6. Restart your Windows for the change to take effect!

    Just goes to show that old web myths never die – they just get rehashed and flogged off as “great ideas”

    For goodness’ sake:


    Do so and it’s patently obvious the tweak should not have been published here…

    this tweak is a myth and has no effect

    this registry key is only for windows 95, 98 and ME, and it is about unloading the explorer shell extensions when not used. it never made Windows faster, in fact it made it slower by having to reload them. It didn’t ‘t free dlls from any other program than Windows Explorer.

    that registry key is never read by windows 2000 and certainly not windows 7

    According to Microsoft, this doesn’t work on Win 2000 and later.

    Please correct me if I’m wrong, but this “tweak” is primarily for Windows versions and systems that substantially pre-date the “modern” (XP and newer) era. For those reading along:

    1) This former registry entry affects the removal of inactive information from active memory (it does not actually delete DLL’s from a system). Most “new technology” computers won’t be noticeably impacted…

    2) Implementation will not render a computer useless; instead, affected applications will simply have to fully *re*-load when *re*-started…

    FYI – I am a Web Talk RSS subscriber and novice computer geek that just happened to recognize this advisory…
