    Windows 10 is fully capable of clearing memory caches and buffers when necessary or desirable, and it will do a far better job than even the most expert user. There is no benefit in attempting to do so manually and this will in fact impair performance.

    The author of the statements made in the article linked to in post #1 clearly has no understanding how memory is managed in a modern operating system.

    The command:
    "%windir%\system32\rundll32.exe advapi32.dll,ProcessIdleTasks" as shown in the article linked to above does not in fact clear memory. It was never designed to do so. This is a myth that has been passed around the Internet since the early days of XP. I don't know where the idea came from as the official documentation made no mention of clearing memory. I have tried the command in XP and Windows 7 and can confirm this. Memory usage actually increased.

    This explains what the command really does:
    https://social.technet.microsoft.com/Forums/en-US/83e1d0cb-ca82-4703-afe0-9b23d97d3df6/what-does-rundll32exe-advapi32dllprocessidletasks-do?forum=mscomops


    The original Microsoft documentation is no longer available.

    The command mentioned in post #2 will in fact clear memory. But this is a thoroughly BAD idea which will impair performance. Windows is fully capable of clearing unused memory when needed.

    My advice would be to let Windows manage memory as it wishes. That is what the real experts do.

    I searched and ask because I use a few memory intensive programs and it would be extremely beneficial if I could flush the memory since there are a few minor issues in Windows, particularly screen savers that won't activate that typically would and when I do a reboot, everything works like a charm since rebooting flushes memory it's fairly obvious where the problem lies but rebooting all the time may not be needed and can be a bit of a pain. If I could do this manually it would be extremely helpful but it is mentioned that is it no helpful. There must be a advanced solution to this problem that is a fair balance.

    Rather than assuming your problems are due to a lack of free memory after closing memory intensive program it would be a good idea to check this in Task Manager. I strongly suspect that this is not the case at all.

    When I close all the memory intensive programs and, for example, the screen saver continues not to activate, then it can only be a memory flush is needed, you could say one or two of the memory intensive programs is not releasing the memory even after closing but that doesn't help much if I can't do it manually in Windows.

    You are making assuumptions not supported by the evidence.

    There is no assumption or evidence, only a question; that is if there is a memory leak how can I retain that memory so that, such things such a the screen saver activate ?

    Memory leaks must be solved at the source. But I have seen no evidence of a memory leak.

    What is the cause why after using memory extensive programs, the screen saver fails to start without manually activating and only when I restart does this problem disappear ?
