If you try to access an SMB 1 share from Windows 10 you may receive the following error message:
You can’t connect to the file share because it’s not secure. This share requires the obsolete SMB1 protocol, which is unsafe and could expose your system to attack. Your system requires SMB2 or higher.
Enable SMB1 on Windows 10
- Press Windows Key + R to bring up the run dialog and type:
optionalfeatures
- Expand “SMB 1.0/CIFS File Sharing Support” and then check the box next to “SMB 1.0/CIFS Client“
- Click OK
- The installation will now proceed and you should be able to access shares using the SMB 1 Protocol again.
Enable SMB1 on Windows 10 with PowerShell
If you would prefer to do a command line installation, use the following command from an elevated PowerShell Prompt:
Enable-WindowsOptionalFeature -Online -FeatureName "SMB1Protocol-Client" -AllFor more information see:

Thank you for this tip, that made it possible for me to find all the “old” (known in win7) intranet server-candidates also on my new win10 PC.
I really appreciate!

Thanks for info. Didn’t really have time to move multiple shared folders from one server to a newer one just because of one user.

CP This has made my day.. I have been struggling for many hours to get my win 10 pc to recognise my WDMyCloud device attached to the home network, without any luck. This has been a real miracle. Many thanks

Lorenzo Cordini says
Thanks, but what if the SMB 1.0 isn’t included in the Optional Features window popping up?
David Q Romney says
Many thanks; it works. I had to reinstall Win 10, and forgot about the SMB 1.0 issue with my Drobo FS. I works now.
