Enable SMB1 Shares in Windows 10 2004+

Just in case anyone is still dealing with this there does appear to be a functioning work around. It’ll at least get us by until we can finally and fully deprecate our SMB1 shares.

The trick is to add the registry key “ProviderFlags” as a REG_DWORD with a value of 1 (0x00000001) to HKEY_CURRENT_USER\Network

Then reboot or log on/off. It fixes the perpetual “reconnecting” status of the SMBv1 drive at logon and everything has been functioning normally and quickly for users we’ve added that registry key. Only needs to be added to the drive letters under Network that correspond to SMBv1 shares.
