I find today that I can no longer mount my Netgear ReadyNas drive because apparently it is using SMB1 and Windows 10 have disabled since release 1709. This is very problemaic because I need to access these files and because I have lost the admin password for the ReadyNas itself so I cannot login in order to update/reconfigure it to use SMB2 instead.
Microsoft refers me to https://support.microsoft.com/en-us/help/4034314/smbv1-is-not-installed-by-default-in-windows which in turn refers me to https://support.microsoft.com/en-us/help/2696547/how-to-detect-enable-and-disable-smbv1-smbv2-and-smbv3-in-windows-and if I really want re-enable SMB1
And I successfully did re-enable SMB1 by running
Enable-WindowsOptionalFeature -Online -FeatureName smb1protocol
from Powershell as Adminstrator.
However even after reboot I still cannot re-establish connection to my Netgear from Windows Explorer, it gives the same error
What else do I need to do ?
PS C:\WINDOWS\system32> Get-WindowsOptionalFeature –Online –FeatureName SMB1Protocol

Solution
Thanks Bob, SMB 1.0/CIFS File Sharing Support was enabled but within it SMB 1.0 Client was not enabled, checking that box and rebooting fixed the issue.

The problem was that although I had sucessfully reinstalled SMB1, the SMB1 client had not been enabled, so if you hit this problem there are two stages.
First Reinstall SMB1.0
Now re-enable Client Support
