If you have spent any real time on a Mac, Quick Look is probably baked into your muscle memory. Select a file in Finder, tap the spacebar, and you get an instant full-size preview — no app launch, no waiting. It works on images, PDFs, videos, Office documents, and more. Move to the next file with an arrow key. Dismiss it with another tap of the spacebar. It is one of those features that feels so obvious you assume every operating system must have it. Then you sit down at a Windows machine in 2026 and discover that, no, Windows Explorer still does not offer anything comparable out of the box. Fortunately, the situation is better than it used to be — if you know where to look.
TL;DR: Windows 11 has a built-in preview pane that is adequate but awkward. A free third-party app called QuickLook fills the gap almost perfectly, and it has been steadily improving for years. It is still the fastest route to a Mac-like spacebar preview experience on Windows.

Why Windows still does not have this built in
Apple introduced Quick Look in Mac OS X 10.5 Leopard back in 2007. That is nearly two decades ago. In the time since, Microsoft has shipped multiple major versions of Windows, rebuilt the Start menu several times, redesigned File Explorer's toolbar at least twice, and introduced an entirely new default browser. What it has not done is add a spacebar preview. The omission is genuinely baffling — it is the kind of small, high-frequency interaction that makes a real difference to daily productivity, especially for anyone working through large folders of images, PDFs, or design assets.
"Quick Look is a quick preview feature developed by Apple Inc. which was introduced in its operating system Mac OS X 10.5 Leopard. The feature was announced at the Worldwide Developers Conference on Jun. 11, 2007."
Microsoft's answer, when pressed, seems to be that the preview pane covers the use case. It does not, really. A narrow side panel that requires you to resize the Explorer window is not the same thing as a large, keyboard-driven overlay that appears instantly and disappears just as fast. The two experiences are not in the same league.
The built-in preview pane
If you cannot install third-party software — perhaps you are on a managed work device with strict administrative policies — the built-in preview pane in Windows 11's File Explorer is worth knowing about. It is disabled by default. To enable it, open File Explorer, click the View menu, and select Preview pane. A panel appears on the right side of the window showing a preview of whatever file you have selected.
It works, and for a quick sanity check on a single file it is fine. The limitations become obvious quickly though. The preview area is small unless you drag the divider across, which then squashes your file list. There is no keyboard shortcut to summon and dismiss it on demand. It renders some file types slowly. And it simply does not support the range of formats that a dedicated tool does. Use it if you must, but do not stop there.
QuickLook — the app that fills the gap
QuickLook is a free, open-source application available from the Microsoft Store. It was first released in 2017 and has been actively maintained and improved ever since. By 2026 it has accumulated a substantial install base, strong ratings, and a plugin ecosystem that extends its format support well beyond what ships in the base package.
Installation is straightforward. Search for QuickLook in the Microsoft Store, install it, and launch it once. It runs quietly in the system tray from that point on. Select any file in File Explorer and press the spacebar. A large, clean preview window appears immediately. Press the spacebar again, or hit Escape, and it disappears. Arrow keys move through other files in the same folder. It is, in short, exactly what you wanted Windows to do in the first place.
Out of the box, QuickLook handles images, PDFs, plain text, Markdown, HTML, audio, and video. The plugin system extends this to formats including Microsoft Office documents, EPUB ebooks, 3D model files, and more — each available as a separate install from the Store or via the project's GitHub page. This is actually one area where the Windows implementation now exceeds what macOS Quick Look does by default, since the plugin library has grown considerably in recent years and covers some niche formats that Apple has never prioritised.
PowerToys — a second option worth knowing about
Microsoft's own PowerToys utility suite, which has become a genuinely useful collection of power-user tools for Windows 11, includes a feature called Peek that was introduced specifically to address this gap. Like QuickLook, Peek lets you preview files without opening them, triggered by a keyboard shortcut. It integrates with the PowerToys ecosystem, which means if you already have PowerToys installed for features like FancyZones or PowerRename, Peek comes along for the ride at no extra cost.
Peek is a credible option and worth trying if you are already a PowerToys user. That said, QuickLook remains the more polished experience for most people — its preview window feels closer to the macOS original, its plugin support is broader, and it has had longer to mature. The fact that Microsoft felt compelled to build Peek at all is at least an acknowledgement that the spacebar preview gap is real and that people have been asking for a solution for a long time. It is just a shame it took this route rather than building the feature properly into File Explorer itself.
Which one should you use?
If you want the closest equivalent to macOS Quick Look with the least friction, install QuickLook from the Microsoft Store. It is free, it is actively maintained, and it works exactly as you would hope. If you are already running PowerToys, give Peek a try first and see whether it meets your needs — fewer installed apps is generally a good thing.
Either way, the core frustration remains: this should not require a third-party tool in 2026. Quick Look has been a defining feature of macOS for nearly twenty years. Windows users who have never used a Mac do not know what they are missing. Those who have used both platforms feel the absence every single day.
