Creating a local network between two computers isn't just a way to transfer a few gigabytes of movies or photos, but also the foundation for organizing printer sharing, document collaboration, and even LAN gaming sessions. Windows 10 This process is significantly simplified compared to previous versions, but hidden security settings and network profiles often become an obstacle for beginners who find that computers simply "don't see" each other.
Before you move on to complex manipulations with the command line or the registry, you need to make sure that the basic conditions are met correctly. Physical level The connection must be stable: both devices must be within range of the router's signal or connected to the same access point. If you plan to use a direct computer-to-computer connection without a router, the steps will be different, but in this guide, we'll cover the classic Wi-Fi router connection, which is the most reliable.
The main difficulty users encounter stems from the network profile Windows assigns to the connection by default. The system, relying on maximum security principles, assumes you're in a private location, such as a cafe, and therefore blocks detection of other devices. Our task is to convince the operating system that we're in a trusted environment and configure the appropriate sharing settings.
Checking equipment and preparing for work
The first step should always be to troubleshoot the physical connection. Make sure both computers have the correct Wi-Fi drivers installed and are functioning correctly. It's common for one laptop to operate in the 5 GHz band, while the other, older one, only supports 2.4 GHz. This is normal; modern routers can handle traffic between bands, but both devices must be connected to the same SSID.
It's also worth checking whether your antivirus or built-in Windows firewall is blocking local detection. Sometimes third-party antivirus packages They may have their own firewalls, which are more stringent than the system settings. If you use complex corporate security policies or specialized security software, their settings may require special attention, but for home use, standard OS tools are sufficient.
⚠️ Attention: Make sure both computers are connected to your home network, not to a guest network if one is configured on your router. Guest networks are typically isolated from the main LAN, and computers on them won't be able to exchange data with each other.
For a successful connection, it is also important that discovery services are enabled on both devices. Windows 10 relies on protocols LLMNR And NetBIOS for naming computers on the network. If these services are disabled for optimization purposes, the system may simply be unaware of the existence of a network neighbor, even if the IP addresses are on the same subnet.
Setting up a network profile and discovery
The key is changing the network profile from "Public" to "Private." This setting dictates which ports to open and how aggressively Windows advertises itself on the network. To do this, open the network settings from the system tray or the Start menu, select your Wi-Fi connection properties, and switch the radio to the "On" position. Private.
After changing your profile, you need to enable discovery features. Go to "Control Panel" -> "Network and Sharing Center" and click "Change advanced sharing settings." Here you'll need to enable network discovery and file and printer sharing for the current profile. Without this step, your computer will be blind and deaf to external requests.
- 📡 Network Discovery: Allows the computer to see other devices and be visible to them in the list of network resources.
- 🖨️ Printer Sharing: Allows other network users to send print jobs to your printer.
- 🔐 Password protection: Determines whether you need to enter your account login and password to access files (recommended for security).
Be sure to save your changes by clicking the corresponding button at the bottom of the settings page. Sometimes, restarting network services or even a complete computer reboot is required for the new settings to take effect and apply to the network stack.
Setting up shared access to folders and files
Once the computers have "seen" each other, you need to determine what exactly they will share. You can share a specific folder or grant access to the entire drive (which is less secure). To do this, right-click the desired folder, select "Properties," and go to the "Sharing" tab.
Here you'll be offered two options: simple (quick access) and advanced permissions. In most cases, for a home network, simply click the "Sharing..." button and add a user. All with "Read and Write" permissions. This will allow any device on the network not only to read files but also to write new ones or delete old ones.
It's important to understand the difference between "Read" and "Edit" permissions. If you grant access to guests or children, it's best to limit access to read-only permissions to prevent them from accidentally deleting important documents or introducing viruses into the shared folder. Full permissions are required for administrative tasks or project work.
| Access type | Description of features | Recommended use |
|---|---|---|
| Reading | Viewing and copying files | Media libraries, document archives |
| Reading and writing | Full control over files | Work folders, data exchange between your PCs |
| Owner | Full control + change access rights | For network administrator only |
The path to the shared folder on the network will look like this \\Computer_Name\Folder_NameRemember the computer name; you'll need it for a direct connection if automatic detection fails for some reason.
Mapping a network drive for convenience
Constantly navigating network paths through the "Network" section in File Explorer is inconvenient, especially if you access shared resources regularly. It's much more efficient to mount the remote folder as a local drive, for example, by assigning it a drive letter. Z:Then the system will think that you simply have a new hard drive partition.
To do this, right-click "This PC" in File Explorer and select "Map network drive." In the window that opens, specify the drive letter and path to the folder in the following format: \\PC-NAME\ShareIf the system asks for credentials, enter the login and password for the account on remote computer whose folder you are connecting to.
⚠️ Attention: Accounts on both computers must have passwords. Windows 10, by default, prevents network access to accounts without a password for security reasons. If you don't want to set a password, you'll have to change complex security policies through
gpedit.msc, but this reduces the security of the system.
Check "Reconnect at logon" to ensure the drive remains accessible after a reboot. This will save you from having to reconnect each time.

Solutions to common problems and errors
Even with proper configuration, Windows can still exhibit behavior. One of the most common issues is the "Windows cannot access..." error, where the system reports that the device or path is unavailable. This is often due to a service Support SMB 1.0 disabled, and the old device or NAS requires this protocol, although it is not recommended to use it due to vulnerabilities.
It's also worth checking the "Function Discovery Resource Publishing" service. If it's stopped, the computer won't be visible in the list of network devices. Start it via services.msc and set the startup type to "Automatic." This is especially important for older versions of Windows 10 or after major system updates.
Sometimes resetting network settings helps. In the network settings, there's a "Reset network" button that will reinstall your network adapters and reset all settings to factory defaults. This is a drastic, but often effective, solution if all else fails.
What to do if computers see each other but don't connect?
Try disabling your antivirus software while performing diagnostics. Also, check if your router is blocking traffic exchange between clients (AP Isolation). This feature is often enabled by default on guest networks or hotspots.
Another important consideration is time. Make sure both computers have the same time and date. A time difference of more than a few minutes can lead to Kerberos authentication errors, and the system will simply not allow you to access resources.
Alternative methods of data transfer
If you're too lazy to bother with LAN setup or only need it occasionally, you can use built-in Windows 10 features like Nearby Share. This technology uses Bluetooth and Wi-Fi to transfer files between nearby computers without having to create shared folders.
To enable this feature, go to "Settings" -> "System" -> "Sharing" and toggle "Nearby Share." Now, when you send a file using the "Share" context menu, you'll see your second computer in the list of available devices. This is convenient for quickly sharing a couple of photos or documents.
- 🚀 Speed: Depends on the speed of Wi-Fi and Bluetooth, usually lower than SMB.
- 🔒 Safety: Confirmation of file receipt on the second device is required.
- 📱 Compatibility: Works only between Windows 10/11 devices.
Also, don't forget about cloud storage or creating a HomeGroup (although in new versions of Windows 10, HomeGroup functionality has been deprecated in favor of OneDrive and personal sharing). For continuous work with large amounts of data, a traditional local network remains the undisputed leader in speed and stability.
FAQ: Frequently Asked Questions
Is it possible to combine computers if one is on Windows 10 and the other is on Windows 7?
Yes, this is possible, but it requires additional configuration. On Windows 7, you'll need to enable SMBv1 support (which is insecure) or, better yet, configure access via IP address and ensure NetBIOS is enabled on both computers. You may also need to use the same usernames and passwords on both machines for easier access.
Why does the system require a password when I try to log in, even though I didn’t set one?
By default, Windows requires a password for network connections. You can disable this request in "Advanced sharing settings" by selecting "Turn off password-protected sharing." However, this leaves your computer vulnerable to attacks from any device within Wi-Fi range.
How to find out the IP address of the second computer for direct connection?
On the second computer, open the command prompt (cmd) and enter the command ipconfigYou are interested in the "IPv4 address" line. To connect, enter \\192.168.x.x (substituting the real address).
Does a router affect the speed of file transfer between computers?
Yes, directly. If your router only supports 802.11n, but your adapters support 802.11ac, your speed will be limited by the router. Furthermore, if both computers are connected to the same router via Wi-Fi, your traffic will go through it, which can reduce your actual throughput by half compared to a wired connection.
