Minimserver in Windows Explorer - normal flip-flop or clue?

[Charles7]

No, the flip-flop has ceased. Sometimes when I exit Minimserver, typically via the icon in the hidden tray of the taskbar, I cannot restart it with the Start button | Programs | Minimserver. Typically, I restart Windows 10 (I have an entry in C:\Users\user-me\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup). )

Java is up to date.
