Gemini App for Windows: Install, Alt+Space, Requirements

If you have spent the last year hunting for the browser tab where you left Gemini, that habit can end. Google has shipped a desktop Gemini app for Windows, so the assistant now opens on top of whatever you are already working in. This guide covers the requirements, the install, and the one shortcut conflict that catches most people on day one. Information is current as of September 11, 2026.

The short answer: the Gemini app for Windows shipped on September 10, 2026

Google announced on September 10, 2026 that the Gemini app is available for Windows 10 and Windows 11, rolling out globally in every country and language where Gemini is already offered. There is one place to get it: gemini.google/desktop. Once installed, Alt + Space summons Gemini over your current window.

That single shortcut is the whole point of the app. Instead of switching to a browser, finding the tab and pasting context in, you call Gemini where the work already is — a half-written email, a spreadsheet, a PDF open in a viewer.

Installing it does not mean everyone gets everything, though. There is a CPU requirement worth checking, several features sit behind a Google AI subscription, and Alt + Space has belonged to Windows itself for decades. Each of those is covered below.

Gemini desktop requirements at a glance: OS, CPU and account

The official desktop page spells out the requirements, and they are short. Three things decide whether the app will run for you: the operating system, the processor architecture, and the Google account you sign in with.

Operating system and CPU: Windows covers both x64 and ARM64

The Windows app runs on Windows 10 or later, on both x64 and ARM64. That ARM64 support matters in practice, because it means Snapdragon-based Windows laptops are included rather than left out. The macOS app is narrower: it requires an Apple Silicon MacBook running macOS Sequoia (15.0) or later.

Account, sync and the subscription line

Sign in with a Google account and your chats and memory sync across desktop, web and mobile. A question you start on the PC continues on your phone without re-explaining anything, which is the quiet benefit most people notice in week two.

Google also states plainly that some features require a Google AI subscription and are limited to users 18 or older. The official notes name Gemini Spark and Gemini Omni among them. So a free account can run the app and still find that specific buttons do nothing — that is licensing, not a bug.

If you are still deciding which plan to buy before rolling anything out, our guide to Google Gemini for business, including setup and pricing, lays the tiers out side by side.

How to install Gemini on Windows 11 and Windows 10

1. Open gemini.google/desktop. Visiting from a Windows PC offers the Windows installer. Use this page only — installers for popular AI apps are a favourite target for look-alike download sites.
2. Download and run the installer. Google describes the app as lightweight so it does not slow the machine down, which is the relevant claim for something you intend to leave resident all day.
3. Sign in with the Google account you actually use for Gemini. Choose deliberately here. If work and personal accounts are both in play, the one you pick is the one that owns your history and memory from now on.
4. Press Alt + Space to confirm it works. Gemini should appear over your current window. If nothing happens, open it from the taskbar or system tray icon instead — and then read the troubleshooting section below, because the app is probably fine.

What you can actually do with Alt + Space

Everything Google lists for the desktop app shares one assumption: you are mid-task and do not want to leave what you are doing. The published capabilities are:

• Summarise long documents, polish drafts and brainstorm — the bread-and-butter work, done without leaving the document.
• Image generation with Nano Banana — visuals for a deck or a post, generated in place.
• Video generation with Gemini Omni — video, which is a separate model from the image work above.
• Multi-step automation with Gemini Spark — Google describes Spark as a round-the-clock personal AI agent that handles a sequence of steps from one instruction.
• Pulling information from Google apps such as Gmail and Google Drive, so "find what we agreed with that supplier" does not become a manual search.
• Working with files stored locally on the PC — the capability that makes this more than a browser tab, and the one with the biggest policy implications.

Windows vs macOS: what the Windows app does not have yet

Honestly: the macOS app shipped first and currently does more. Google's desktop page says so directly, listing native macOS capabilities — screen context sharing, dictation, editing content across applications, and Gemini Spark's local folder integration — and notes that more native features are planned to reach Windows over time.

In practice this bites mixed-hardware teams. A Mac user demonstrates something in a meeting, the Windows half of the room cannot reproduce it, and everyone concludes the rollout is broken. If you write an internal how-to, split it by operating system from the start rather than patching it later.

"Alt + Space does nothing" — what to check, in order

This is the day-one problem. Alt + Space is a long-standing Windows shortcut that opens the active window's system menu — Move, Size, Close. And if you run Microsoft PowerToys, PowerToys Run claims Alt + Space by default too. So "a menu appeared" or "a search box appeared" usually means something else got the keystroke first, not that Gemini failed.

1. Open Gemini from the taskbar or system tray. If it opens that way, the app is healthy and the problem is purely the shortcut.
2. Watch what Alt + Space actually produces. A window system menu or PowerToys Run means you have a conflict. Reassigning the PowerToys Run hotkey is the practical fix; whether Gemini's own shortcut can be rebound is not something Google documents, so we will not invent a procedure for it.
3. Check you are signed in. Without a signed-in Google account there is nothing for the app to show you.
4. Check the OS and CPU. Windows 10 or later, x64 or ARM64.
5. Check whether the feature is subscription-gated. Gemini Spark and Gemini Omni are named as requiring a Google AI subscription, 18+.
6. Allow for the rollout. Global availability still arrives at different moments for different accounts and environments.

At Mihata we spend most of our AI consulting time on exactly this layer — not the install, but deciding who uses a new tool for what, and writing the two or three rules that keep it safe. If your team has stalled somewhere between "installed" and "useful", we are happy to take a look.

Before you roll it out to a team

A desktop app is not just the browser version with an icon. Because it can reach files stored locally on the PC, the questions change. Four decisions, made before the install rather than after an incident, cover most of it.

1. How far into local files does it go?

A normal working desktop holds quotes, payroll spreadsheets and signed contracts. Agreeing one line — "personal data and contracts are out of scope" — before anyone starts removes most of the risk for almost no effort.

2. Which account does everyone sign in with?

History and memory follow the account. Months of work conversations under a personal Gmail address are unrecoverable when that person leaves or swaps laptops. For business use, standardise on company accounts.

3. What is the policy on what people paste?

Someone should check how submitted content is handled, and the answer should be written down rather than assumed. Our notes on preventing AI data leaks and setting a workplace AI policy cover the settings and the short policy that goes with them.

4. When do people use the app, and when the browser?

The split we see most often: the desktop app for quick questions and anything involving what is on screen right now, the browser for long, deliberate document work. You do not have to choose one. If your team also runs other assistants, our comparison of ChatGPT, Claude and Gemini for 2026 covers where each one fits.

Bottom line

The Gemini app for Windows has been available from gemini.google/desktop since September 10, 2026. The requirements are short — Windows 10 or later, x64 or ARM64, a Google account — and Alt + Space is how you reach it.

If something goes wrong, it is almost certainly one of three things: a shortcut conflict, a subscription-gated feature, or a capability that only macOS has so far. Check the requirements table first, and when Alt + Space is silent, open Gemini from the tray to tell a broken app apart from a stolen keystroke.

Where teams genuinely get stuck is the next question: which parts of our actual work does this improve? If you would rather work that out with someone who builds AI into day-to-day operations for a living, get in touch.
