  2. I upgraded and it keeps using more and more memory, my disk usage is 100% live tiles do not workRuntime Broker.

    Hi,

    Welcome to the Microsoft Community.

    Runtime Broker is a Windows process in Task Manager that helps manage permissions on your PC for apps from Windows Store. It should only use a few megabytes of memory, but in some cases, a faulty app might cause Runtime Broker to use up to a gigabyte of
    RAM or more.

    If your RAM use is high and your PC is running slowly, an app may be the cause of the problem. Press Ctrl+Shift+Esc to open Task Manager and then, on the
    Processes tab, check to see how much memory Runtime Broker is using. If it’s using more than 15% of your memory, you probably have an issue with an app on your PC. To stop Runtime Broker from using so much memory, select
    Runtime Broker in the list, select End task to close Runtime Broker, and then restart your computer.

    Thank You.

  5. Here's a temporary fix I made myself. Note that while I have yet to find any consequences I'm sure there's some, however it fixes the current issue.

    EDIT: The method below eventually disables the start menu from opening. As I stated I knew it would cause issues, so I do not recommend it but will leave it for the curious.
    1. Go to C:\Windows\System32\
    2. Find RuntimeBroker.exe then right click and go to Properties.
    3. From there select the Security tab then click Advanced.
    4. At the top where it shows Owner (TrustedInstaller) click Change.
    5. In the window that pops up type in your full user name with spaces then click Check Names.
    6. If an error pops up you typed your user name wrong, if not press OK then OK again on the Advanced Security Settings for RuntimeBroker window.
    7. Now you should be back at the RuntimeBroker Properties window, again click the Advanced button to reopen the Advanced Security window.
    8. There will be around five items in the list on this window. One by one double click them and remove the check mark next to the Read & execute, leaving the others alone (this may automatically unselect some other check boxes, don't worry).
    9. After you have done this to all of them click OK back at the Advanced Security Settings window then OK on the RuntimeBroker Properties window.
    10. Finally go to the task manager and select the RuntimeBroker process and hit End task. Problem solved.

    Yeah, it manages security permissions for the Windows Store, modern/metro, apps.

    Try stopping the store apps from being allowed to run in the background.

    Go to: Settings->Privacy->Background Apps

    I assume this prblem with runtime broker and the fact that live tiles since upgrading do not work is no coincidence. will stopping the store apps from being allowed to run in the background mean i can not ever have live tiles? i would really like those to work

    With process explorer I discovered that buffer overflow accessing registry keys is the problem

    Rename :


    HKEY_CLASSES_ROOT\Extensions\ContractId\Windows.BackgroundTasks\PackageId\Microsoft.Windows.ContentD eliveryManager_10.0.102

    40.16384_neutral_neutral_cw5n1h2txyewy\ActivatableClassId



    to any other name, pe. adding a S to the end of the name.

    Problem solved.

    Hi,

    Yes, search for the key in registry editor ( ActivatableClassId ) and right buttom / rename to ( ActivatableClassIdS ) , the runtime broker stops its activity just after the change (tested in two machines)

    If yoy did that thing Nus suggested ("Try stopping the store apps from being allowed to run in the background. Go to: Settings->Privacy->Background Apps ) , then after the change in the registry I suggested you can Undo that Settings->Privacy->Background Apps change and Live tiles will work again.

    If not and there is another problem I dont't know the solution *Wink

    Just turn off 'Show me tips about windows'

    Setting - System - Notifications and actions

    My CPU usage dropped immediately from 30% to 0%

    Whatever the problem was it stopped. I think other people had the problem and microsoft sent an update
