Since windows update 1803, on my two computers a sub menu appears randomly.
The text for that menu is located in the system32 folder in a temporary file created by applicationframehost.exe
I believe that file is named applicationframe.exe.mui It contains the text of the small menu that randomly appears in the left top corner
of the desktop or a running program. The items print and share do nothing... the settings brings up a blue dialog box on the left side of the screen that is entitled SETTINGS. This box is empty.
This behavior started when 1803 was installed. The little sub menu disappears when I end task on windowsframehost.exe process. Due to the random nature of its appearance, I am suspicious that fences or start 10 is sending out the system call. The MS Answer desk has not
seen this problem and suggested that the applicationframehost is tightly tied to the menuing process.
Anyone have any thoughts or that experience? as seen below...
