For years, dual-booting Windows and Linux felt like the only sensible way to have the best of both worlds. Windows was still the default for gaming, certain professional software, and hardware compatibility, while Linux was the environment many developers and power users preferred for its tooling, flexibility, and open ecosystem.

The problem was that dual-booting always comes with friction. Besides needing a full reboot to swap operating systems, the potential for the bootloader to be overwritten by Windows Updates combined with the juggling of partitions meant dual-booting was a rather frustrating experience. Windows Subsystem for Linux, or WSL, removed all that friction, and provided what I needed from Linux without me needing to leave my Windows desktop.

WSL gives you the full Linux experience (almost)

All without leaving your desktop

While the original version was more of a compatibility layer than a true Linux environment. WSL2 introduces a real Linux kernel running inside a virtual machine so light, you barely notice it's there. From a terminal perspective, it behaves almost exactly like a normal Linux system: you can install your favorite distribution from the Microsoft Store, use a familiar package manager, and run most command-line tools without needing any further modification.

It also integrates with Windows pretty seamlessly, allowing you to access files directly from within the Linux environment, launch applications, open project directories, and more. It feels like using two different operating systems that are linked extremely well in file structure, and that's something that dual booting can't really provide.

WSL allows you to dodge the headaches that come with dual-booting

Windows and Linux can live in harmony

One of the biggest downsides of dual-booting is the time that it takes to switch between the two operating systems. It might not seem like a lot the first time, but waiting up to a minute every time you want to swap over gets really old after a while, even with a fast SSD.

Speaking of getting old quickly, having your bootloader overwritten by Windows update is another massive headache that using WSL dodges completely. I can't tell you how many times I've had to repair GRUB when dual-booting, but I can tell you it's too many.

Networking and hardware passthrough are not seamless

I'd still use bare metal for these applications

Despite how capable WSL has become, it still behaves like a virtualized environment in a few important ways, particularly when it comes to networking and hardware access, where it's actually worse than regular virtualization.

Networking is the most noticeable example. By default, WSL runs behind a virtual network adapter using NAT, which means it doesn’t behave exactly like a normal machine on your local network. Services running inside WSL often need additional configuration before they can be accessed from other devices, making anything that needs port forwarding, firewall rules or specific IP addressing quite annoying to set up.

Hardware passthrough is another pain point for WSL. GPU acceleration works for certain workloads, and USB devices can sometimes be forwarded, but it’s not the same as running Linux directly on the hardware. Low-level access to devices, kernel modules, and specialized drivers can be restricted or behave differently compared to a native Linux installation.

You can get hardware passthrough and networking to work well

It's possible, just not super practical

One of the biggest improvements to WSL networking in recent updates is mirrored networking mode. The NAT interface WSL runs behind a NAT interface, which means the internal IP address assigned could change frequently, making hosting anything from it a huge pain. If you wanted to get around this, you usually have to set up port forwarding through Windows or manually configure firewall rules. And that's before VPNs get involved. Once you start playing with those, it's basically not even worth your time.

Mirrored mode changes that by making the WSL instance share the host machine’s network interfaces instead of sitting behind a virtual NAT. In practice, this means services running in WSL can be accessed through the same IP address as your Windows system, just like any other application running on the host. It also improves compatibility with things like VPNs, multicast networking, and basically anything that previously struggled with WSL’s virtual network layer.

Hardware access in WSL isn’t traditional passthrough in the way you’d see with a VM or a native Linux install. Instead, WSL relies on Windows to expose certain devices to the Linux environment through virtualization layers and drivers. That means access is possible, but it usually requires specific tooling and only works for supported device types. One common example is USB device passthrough. With the usbipd-win tool, you can attach USB devices from Windows to a running WSL instance. After installing the tool and listing connected devices with usbipd list, you can attach one to your Linux environment using the usbipd-win attach command. GPU passthrough is better, and much more straightforward if you have a card with CUDA, but it's not designed for full desktop use, and there are strict limitations.

Dual-booting is no longer the only option

Dual-booting used to be one of the only ways to bridge the gap between Windows and Linux. If you wanted access to Linux tools without giving up Windows completely, it was either that or running a heavy hypervisor. That was simply the price of doing business. With WSL, it doesn't have to be that way. It certainly has its warts, but it lets Windows and Linux coexist on the same machine with surprisingly little friction.
