Connecting a laptop to a desktop PC can be a useful solution when you need to share files, extend your display or access one device remotely from the other. Whether you are a student working across two machines or a professional setting up a dual-system workspace, there are several simple ways to establish a connection between a laptop and a PC using either a wired or wireless method.
In this guide, we will explore the main ways to connect your laptop to your PC. We will also explain when each method is useful and how to set it up step by step.
Why Connect a Laptop to a PC
You might want to connect your laptop to a PC to transfer files quickly without needing USB drives or cloud services. It is also helpful if you want to use one machine to access or control the other remotely. For example, you might use a laptop to control a more powerful desktop when working on resource-heavy applications. You can also use your laptop as a second screen for extended display purposes.
Using a Local Network to Share Files
One of the easiest ways to connect a laptop to a PC is by sharing files over a local network. First, make sure both devices are connected to the same Wi-Fi network or linked by Ethernet. On each device, open the Settings app and go to Network and Sharing Centre.
Enable File and Printer Sharing and then select the folders you want to share. Right-click a folder, choose Properties then go to the Sharing tab. From here, click Share and choose who you want to give access to.
On the other device, open File Explorer, go to Network and you should see the name of the other machine. Double-click to access the shared folders and start transferring files.
Using Remote Desktop Connection
If you want to control your PC from your laptop, you can use Remote Desktop Connection. This feature is built into Windows Pro editions.
On the PC you want to control, go to Settings > System > Remote Desktop and enable Remote Desktop. Take note of the PC name listed under this setting.
On your laptop, search for Remote Desktop Connection in the Start menu. Enter the name of the PC and click Connect. You will need to enter the login credentials of the desktop to gain access.
Once connected, your laptop acts as a window into the PC, allowing you to use it as though you were sitting in front of it.
Using a Laptop as a Second Monitor
If you want to use your laptop’s screen as an extra display for your desktop PC, Windows 10 and 11 offer a feature called Projecting to this PC.
On your laptop, go to Settings > System > Projecting to this PC and enable the option to allow your PC to project to it.
On your desktop PC, press Windows key + K then select your laptop from the list of devices. Choose to Extend the display so your laptop becomes a second screen.
This feature uses Miracast, so both devices must support it. Wired alternatives using HDMI are not supported for using a laptop as a monitor since most laptop HDMI ports are output only.
Using a USB Transfer Cable
For a fast and direct file transfer, you can use a USB transfer cable. These cables include a special chip that allows data to be shared between two computers. You will also need software, often provided with the cable, to manage the transfer.
Plug the cable into both the laptop and PC then open the software. You will see the file systems from both devices and can drag and drop files between them easily.
This method is particularly handy if you do not have access to a Wi-Fi network or want to transfer a large number of files quickly.
Final Thoughts
There are many practical reasons for connecting a laptop to a PC and several straightforward methods to do so. Whether you want to transfer files, extend your display or take remote control of a device, Windows offers built-in features that make it simple. Choose the method that fits your needs best and always make sure both devices are on the same network or securely connected.
