What happens when you close your Electrum wallet? Are there any Electrum processes in the task manager then? Maybe you just opened it a few times and it didn't close properly or it could be a temporary bug.
Have you tried restarting your computer and opening Electrum after a fresh restart? Is there just one process after a fresh restart?
No, it always seems to be 2 processes, even immediately after a restart.
The offline Electrum, running on Windows 10, only seems to have 1 process showing in Task Manager.
I'll try installing a watching Electrum wallet under Windows 10, and report back
