Windows.Storage.Search.dll high CPU usage


I am observing this behavior from several days, when I use my PC after sometime of inactivity, Runtime Broker start using high CPU usage. When I check it using process explorer, there are two threads that caused high CPU usage.



Windows.Storage.Search.dll!GetGatherAdmin+0xd2e0
windows.storage.dll!SHGetNameFromIDList+0x1c0



But I don't understand what these are and how to stop this issue? Any advice?


Answer



The Runtime Broker tries to read a thumbnail windows.storage.dll!CFSFolder::_GetThumbnailCacheId and this casues a high CPU usage. But I can't see which process/app triggers this call. Close all of the Store Apps (Microsoft.Windows.Photos is a good candidate) and see what happens.
