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.
You can enable SMB 1 on Windows 10 using the steps below.
Time needed: 2 minutes.
Enable SMB v1 on Windows 10 with the GUI
- Go into Windows Optional Features Window
Press Windows Key + R to bring up the run dialog and type:
optionalfeatures
- Install SMB 1 Support
From the turn Windows Features on or off Window, 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.
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.
