Free System Memory Quickly!

Free your system memory by using this simple trick.

Have ever you noticed that all your used system resources are freed up when you restart your computer? – Your system runs much faster after restarting that’s because it frees up all the system memory that was used in the last session.

Using the trick that you are about to be introduced, you can restart your system (“free system memory”) with just a single click and it only takes a few seconds.

Just follow the below instructions to get started:

  • Right Click anywhere on the empty desktop and Select – New -> Shortcut.
  • When prompted with a box to select a file,  Type or Copy/Paste the following: %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks
  • Then finally you can give your shortcut a name “Quick Restart” or anything you like.

In the end when its all said and done – all you have to do now is double click the newly created shortcut to free up your system / computer memory and you will notice your system being alittle more optimized.

You can also change your shortcut icon to make it appear different on the desktop 🙂

Try this out when you feel your computer is starting to run slow and you will see the difference.

Note: It would be best if you closed any open applications before attempting this trick (if possible).

  1. Thanks, it worked.

    I use many heavy applications, i thought to try this out after closing the applications such as AutoCAD and 3DSMAX.

    And it really helped for sure 🙂 keep up the good work!

  2. I must be doing something wrong with this shortcut. It is a great idea and a wonderful tip. I have created the shortcut but it says the location cannot be found.

    Anyway, great idea.

  3. That was so easy! Thanks for it worked brilliantly smooth! I use TuneUp Utilities for freeing the computer memory but I’m having trouble when using other programs along with it. The computer get’s stuck-up especially when it starts to defrag.

    Wonderful tip, you’re a genius!

  4. I’m running Windows XP. When I pasted in
    %windir%system32rundll32.exe advapi32.dll,ProcessIdleTasks
    and clicked next, I got a “file not found” error and could not proceed. I can browse for a file–can you provide the directory path? Thanks.

    1. @Jazzminjoy:
      This file resides in the system32 folder – the path would be “C:\WINDOWS\system32\“.

      Sorry you were having trouble though – But i just tried adding again by entering this and it worked:
      %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks

      Let me know if that helps

  5. Thanks alot – it worked smoothly indeed.

    i was having a issue – when i was copying and pasting the code:

    %windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTask

    it was for some reason adding a line break, right after rundll32.exe

    i copied the entire text first to notepad and then added it to the short-cut and it worked!.

  6. Pretty good post. I just found your blog and wanted to say
    that I have really enjoyed browsing your blog posts. In any case
    I’ll be subscribing to your feed and I hope you write again soon!

  7. does this work for vista as well? i tried to add shortcut and it said “The file “%windir%system32rundll32.exe advapi32.dll,ProcessIdleTasks” cannot be found.”

    1. @Abdul Rehman:

      sorry mate, but i don’t think it would work on Window Vista since i think they both have different files and structure.

      It might be possible maybe but that would mean to find the required files manually, and if they exist theres a chance it might work but can’t guarantee that since i haven’t been able to test it on Windows Vista.

  8. The author has misunderstood the function of this command. By default, Windows schedules a number of system maintenance tasks that are run during idle time every 3 days. These are the “idle tasks”. Running the command starts these tasks now, even if the system is not idle. This can impact application performance.

    The command does not free memory, as will be quite obvious if you have Task Monitor open while running it. Windows manages memory very well on it’s own without such hacks.

    In some unusual cases this command may appear to be beneficial. But that is not it’s purpose and will not be the normal case.
