Just did a clean install of Windows 10 (version 1511 build 10586.446).

I notice something weird whenever I try to shutdown or restart Windows. Just before shutdown or restart, Windows would flash brief messages about closing certain apps. They include, most commonly, DDE Server Window & Schedule Recover. The warnings flash only briefly and then Windows shutdown or restarts without interruption. This occurs even if I just did a reboot and then shuts down without opening any apps inside Windows.

Back in Windows 7 or Vista days, this usually signifies some apps or programs refusing to close and is hanging up forcing Windows to close them. Is this true also for Widows 10? What can I do to try to troubleshoot this?
