You are Ace!

Good man, thank you

Thank,good guy

thanks so much for this workaround - since months it maddened me to do the unnecessary work or reconnecting manually mapped drives.
it's really unbelievable that microsoft since generations of its operating system is not willing to do the job itself!

UPDATE: your automatic script in the startup folder does a wonderful job.
but windows 10 (version 2004) keeps disconnecting during every session - therefore i have to activate your script several times a day.
i can't express how furious i am ...

Can simplify Cleanup: Closing Explorer windows using following in place of 185-187:
"C:\Program Files\nircmd-x64\nircmd.exe" win close class "CabinetWClass"
