In Windows 10 it seems like a lot of people including me are having a problem with Runtime Broker using a LOT of CPU and slowing down the computer.
Anyone here having problems with it?Not me. Windows 7 Pro 64 bit upgraded to Windows 10 pro. At this time Process Explorer show it having 0.00% CPU and 11.5 MB memory.

"Runtime Broker high CPU usage"

Issue:

A process called Runtime Broker has a high CPU usage in Windows 10 (final release version).

Cause:

Unknown, there seem to be multiple causes and multiple solutions. May be related to OneDrive, permissions for metro apps, Background Task Infrastructure Service, Windows spotlight thingy, windows tips and a number of other apps.

Solutions that work for some:

    Registry hack: run regedit.exe, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\TimeBroker, change "Start"=dword:00000003 to dword:00000004. This will affect parts of Cortana, like NEW apps not showing up and you can't set reminders. After a while, I set the value back to 3 and it's still fixed.
    Switch your lock screen background (Settings -> Personalization -> Lock Screen) from Windows Spotlight to Picture. Preferably but not necessarily a picture of a ninja cat on a dinosaur ;-) Additionally disable the live tile of your photo APP by right clicking on it.
    Settings -> System -> Notifications -> Disable "Show Windows Tips"

If these don't work, your odds of finding a fix have dropped considerably, but you could try:

    Deleted Groove music using powershell. Used these commands: Get-AppxPackage -name "Microsoft.ZuneMusic" | Remove-AppxPackage     Get-AppxPackage -name "Microsoft.Music.Preview" | Remove-AppxPackage    (To bring up powershell, press win+r and type powershell. Hit enter, copy and paste one at a time).
    Disable/delete OneDrive / SkyDrive
    Disable Google Drive if you use it
    Close all programs and restart them one by one to try to find the culprit, uninstall the culprit. Yes, we're in the desperate stage.
    Do a full refresh of Windows 10. But note: many people have the problem persist, even after a vanilla install of Windows 10.
    Send MS an angry e-mail. Wait for them not to respond. Throw a brick through the Windows(R) of your local MS office. Won't fix the problem, will fix your frustration for a while.
