[[Microsoft Windows]] 2.0 first introduced a window switcher in 1990. Using {{key press|Alt|Tab}}, users could see a flattened view of all open windows. Every version of Windows since then has also provided this window switching functionality. Vista and Windows 7 provide an additional feature called [[Windows Flip 3D]], which has a broadly similar purpose. Flip 3D allows a user to flip through all open windows with a three-dimensional perspective. A downside to this method is that the front-most window covers a significant portion of the other windows, unlike Exposé. On the other hand, this allows the user to see the contents of the front-most window, while this can be difficult in Exposé, especially if the user has a large number of windows open. Vista's [[Desktop Window Manager]] exposes a public [[API]] that allows any application to access the same thumbnail representations that Flip3D uses, and so there are a number of third party add-ons that are able to provide Exposé-like functionality in Vista. A very few third-party applications, such as the Emcee Desktop Organizer, provide Mission Control-like organization of similar windows into visual "stacks," or support Windows 8's "Immersive" Apps. [[Windows 10]] adds a very similar feature called [[Task View]] which also includes multiple-desktop support.

Microsoft's Intellipoint Software for Microsoft Mice has a feature similar to Exposé<ref>{{cite web|url=http://www.microsoft.com/hardware/mouseandkeyboard/docs/instant_viewer.html |title=Instant Viewer |website=[[Microsoft]] |url-status=dead |archive-url=https://web.archive.org/web/20110306083514/http://www.microsoft.com/hardware/mouseandkeyboard/docs/instant_viewer.html |archive-date=March 6, 2011 }}</ref> as it also works with live images of windows, rather than static representations.

Microsoft's Windows 7 introduced a feature called "peeking" that allowed a user to hover their mouse over an icon in the taskbar to reveal a small thumbnail depicting the contents of the application's window or windows.[10]

[[Compiz]] and [[KWin]] are compositing window managers for systems using the [[X Window System]]. Both include plugins similar to Exposé - the scale plugin in Compiz and the present windows effect in KWin. [[Skippy (X)|Skippy]] also performs similar functions to Exposé.

Starting with version 3.0, the [[GNOME]] desktop environment has gained a new mode called "Overview", which is used to launch applications and manage workspaces. In this mode, windows are scaled and arranged in an Exposé-like fashion for quick switching.

For Classic or Legacy Macintosh systems, the free Finder Workspaces<ref>{{cite web|url=http://mac.softpedia.com/get/System-Utilities/Finder-Workspaces.shtml |archive-url=https://archive.today/20140319170632/http://mac.softpedia.com/get/System-Utilities/Finder-Workspaces.shtml |url-status=dead |archive-date=2014-03-19 |title=Finder Workspaces 2.2 }}</ref> offers functionality similar to Spaces.
[[ChromeOS]] has a window overview mode<ref>{{cite web|title=The New Overview Feature in Chrome OS|url=http://www.omgchrome.com/chrome-os-adds-overview-mode-mac-style-expose/|website=OMG! Chrome!|date=August 30, 2013 }}</ref> that shows a thumbnail of all open windows, available by pressing the 'window switcher' key or swiping up with 3 fingers on the trackpad. Windows in overview mode can be closed by clicking an associated close button, or selected by clicking on the window thumbnail, which also closes overview mode and brings the selected window to the foreground.
