right-click action within windows 10, "AcroTray" (Acrobat Tray) keeps popping up

Hello DutchGlory

Sorry for the delay in response to your query and apologize for the inconvenience caused.

"AcroTray.exe" is the Adobe Acrobat Distiller helper application. It is used as part of the full Adobe Acrobat product to convert documents into PDF files. Its runs in the background as it provides your feature to convert files to files to PDF using other applications like MS office.

However, if you wish to disable/stop it, please refer and try the steps from the following KB doc what's starting acrotray.exe?

Or can edit the TWO registries by navigating to HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers and  HKEY_CLASSES_ROOT\Folder\shellex\ContextMenuHandlers

Go to the Adobe folder in both locations and modify the "value data" entry by adding a "-" in front of the bracket and it will disable it.

Hope this helps, and let us know how it goes.

Regards,

Anand Sri.
