How to access files on network devices using SMBv1 on Windows 10

Server Bulletin Block (SMB) is a networking file share protocol included in Windows ten that provides the ability to read and write files and perform other service requests to network devices. Unremarkably, y'all'll exist using SMB to connect to devices that don't run Windows, such as a router with file sharing capabilities, Network-Attached Storage (NAS), or other computers running Linux.

Although there take been three major releases of the protocol, there is a gamble that you may notwithstanding have devices running the original version, such as SMB version ane (v1) which is old and insecure, and Windows 10 no longer installs it by default starting with the Fall Creators Update and April 2022 Update. As a outcome, you'll become error messages like "You can't connect to the file share considering it's not secure;" "The specified network proper name is no longer available;" and "Unspecified mistake 0x80004005" when trying to access your files.

All the same, if you take a networking device that yous can no longer access because of this issue, you can even so temporarily enable the protocol to retrieve files.

In this Windows 10 guide, nosotros walk you through the steps to temporarily enable the SMB protocol to regain access to files stored in the network. So, we'll as well explain the procedure to disable it to keep your computer protected.

How to temporarily re-enable the SMBv1 protocol on Windows 10

If you don't have straight access to the device running the SMB service, yous can temporarily enable the SMBv1 protocol for the purpose of retrieving your files using these steps:

Open Control Panel.
Click on Programs.
Click on Plough Windows features on or off link.

Afterwards completing these steps, you'll in one case over again be able to see and connect to network devices running the old protocol on your local network from your Windows 10 computer.

Of class, you lot should only use these steps as a temporary solution to regain admission to your files stored on the network. Ideally, if you're saving your data on a bulldoze connected to a router with file sharing capabilities or NAS, you should contact the device manufacturer for specific instructions to update the device to a version that supports SMBv2.02 or later.

If the manufacturer can't provide an update, you should consider getting a network device that includes support for the more than secure version of the network protocol.

After you lot've either migrated your data off the network or you updated the software that supports the more than secure version of the protocol, we recommend disabling SMBv1 on your computer. You can easily do this following the aforementioned steps mentioned higher up, but on Step No. 5, brand sure to clear the SMB 1.0/CIFS Client option.
