Google released a Gemini desktop app for Windows on September 10, supporting Windows 10 and 11, rolling out globally and available for download at gemini.google/desktop. Pressing Alt+Space from any screen brings Gemini up as an overlay above whatever window is active, without switching to a browser. It's Gemini's second native desktop client, following the macOS version launched in April.
According to Google's blog post, the features include pulling information from connected apps such as Gmail and Google Drive; handing off multi-step tasks to the personal agent Gemini Spark; generating images with Nano Banana and videos with Gemini Omni; plus the usual editing, summarizing, and brainstorming. Google describes the app as lightweight and unobtrusive, saying it won't slow down the computer.
"This is just the beginning for the Gemini app on Windows, with more native desktop capabilities rolling out over time."
What's Missing Compared to the Mac Version
Compared with the Mac version's feature list, the Windows app currently lacks three native capabilities: feeding on-screen content to Gemini as context, cross-app voice dictation, and letting Spark access local folders to organize files. Google hasn't given a timeline for closing the gap.
The requirements for Spark haven't changed either: users must be 18 or older, have a personal Google account, and subscribe to Google AI Pro or Ultra; it's unavailable in the European Economic Area, the UK, Switzerland, and Nigeria. Work and school accounts can use basic chat if an administrator has enabled Gemini, but Spark isn't open to those accounts. On top of that, Windows still isn't listed among Spark's supported platforms on its help page, which doesn't match what the blog post says — whether it actually works should be checked inside the app itself.
The Same Shortcut Already Has Five Claimants
Alt+Space is crowded territory on Windows. According to third-party roundups, the combination was originally the shortcut for the system window menu (move, resize); PowerToys Run also uses it by default; Microsoft's Copilot app has set it as a quick-launch key since December 2024; ChatGPT's desktop companion window uses it too; and Google's own desktop search app, launched in April, bound the same combination. Gemini is the sixth.
Windows handles the conflict bluntly: whichever app launches first and stays running in the background claims the shortcut. OpenAI's help page warns that if the shortcut is already registered by another app, ChatGPT's companion window won't open. In a PowerToys issue report filed last December, users found Copilot and PowerToys Run both holding the same combination, with only one launching at a time depending on which grabbed it first.
Three Assistants, Three Different Footholds
Side by side, the three AI assistants sit in very different positions on Windows.
Copilot comes built into the system, has a taskbar entry, and many new laptops even ship with a dedicated Copilot key, so Microsoft doesn't need to fight anyone over Alt+Space. ChatGPT has to be downloaded and installed separately, and its edge is user base and habit. Gemini also requires a separate install, but its hand is Google services like Gmail and Drive that many people open daily, letting it pull data straight from them.
Seen this way, what Gemini is really after with the shortcut is frequency of use: Gemini in the browser requires switching tabs first, while the desktop app is just one key combination away. Whether it can pull users away from the Copilot key and the ChatGPT window depends on the native capabilities still to come — and on-screen context plus local file access happen to be exactly where Copilot has the biggest system-level advantage.
Gemini's download page marks Alt+Space as a "customizable shortcut." For users who have several assistants installed at once, the simplest fix is reassigning some of them to two-modifier-key combinations, rather than gambling every startup on which one launches first.
