Win10 20H2 fixes the issue.

Previously when 2004 broke smb1, I rolled back.

There was no registry change or any other modification made to the system.  After Win10 20H2 upgrade was installed via Windows Updates;  SMB1 worked as it did before the upgrade.

Thank you Microsoft.

    Updating to 2H04 did not fix the SMB issue for me - still needing to disconnect/remap drives from a ReadyNAS using SMB 1.0 on each reboot.

    "Still can't access after reboot"

    1. in the 'Type here to search' box next to the start menu search for "Windows Features' click 'turn windows features on or off' go down to 'SMB 1.0/CIFS...' click the plus in front, uncheck any checked box in front of the 3 sub item

    reboot when prompted.

    1. go back into 'Windows Features' and put a check in front of 'SMB 1.0/CIFS Client' (only)

    reboot when prompted

    1. after reboot remove(disconnect) all mappings see:

    https://support.microsoft.com/en-us/help/890413/you-may-receive-the-the-local-device-name-is-already-in-use-error-mess

    "To resolve this issue, remove the existing network mapping. Then create a new network mapping for the share."

    That article is regarding connecting to shares on xp or before computers.

    1. Remap your shares.
    2. Reboot-test, Reboot-test  (it stayed working for me on various systems)

    NO registry editing or other settings where changed.

    What are you trying to map to (a linix box, windows box, network storage device, etc)?

    This is not the solution. I tried 20H2. Still can't access after reboot

    you're right friend .... nothing this with new versions of win10 after 1909 always appears the same problem with smb !! "

    is the best solution with reg ProviderFlags

    Windows Registry Editor Version 5.00

    [HKEY_CURRENT_USER \ Network \ K]

    "ProviderFlags" = dword: 00000001

    for K drive
