Key Takeaways
- Check Gemini First: If the Gemini app for Windows won’t reopen, leftover processes can block a fresh launch, while Copilot or PowerToys Run can grab Alt + Space. Try Gemini in your browser with the same Google Account, then open the desktop app from Start.
- Restart and Update: End leftover Gemini processes in Task Manager, reopen the Gemini app for Windows, and select Restart to update if offered. Try the system tray, change conflicting shortcuts, accept the “Open Gemini?” sign-in prompt, and update your graphics driver if you see “GPU process isn’t usable”.
- Reinstall or Use Chrome: If the Gemini app for Windows still fails, ask your admin to check work or school access, or reinstall with GeminiSetup.exe. Screen sharing is Mac-only for now, but you can install Gemini’s website as a Chrome app and access your saved chats.
You close Gemini, press Alt + Space to bring it back, and get Copilot or a whole lot of nothing. If the Gemini app for Windows is not working, end any Gemini processes left running, open the app from Start, and install any update it offers. Then decide which app gets Alt + Space so the shortcut opens the one you expect.
Google released Gemini for Windows 10 and 11 on September 10, 2026. Since launch, some users report that Gemini won’t reopen after they close it, a work sign-in leaves them on the website, or the app fails to start on an ARM PC or a machine with integrated AMD graphics. Which of those sounds like your PC? You can usually narrow it down by trying Gemini in your browser and opening the desktop app from Start. If you get as far as a reinstall, your saved chats sync back when you sign in with the same Google Account.
What the Gemini App for Windows Needs to Run
Before you change a shortcut or reinstall Gemini, compare your PC and account with the requirements Google lists. Basic chat is free, while Gemini Spark and video creation with Gemini Omni require a Google AI subscription and are for users 18 and up. Use the table to check whether you can run the app and sign in.
| Requirement | What Google lists | What to check on your PC |
|---|---|---|
| Windows version | Windows 10 or later | Check the Windows version under About. |
| Processor type | x64 or ARM64 | Look for System type under About. |
| Memory | At least 8 GB of RAM | Check the installed RAM under About. |
| Storage | At least 200 MB free | Check the available space on your drive. |
| Internet | A stable connection | See whether Gemini loads and answers in your browser. |
| Google Account | A personal account or a work or school account with Gemini enabled | Check which account you selected at sign-in. Personal accounts generally require age 13 or the local minimum. Work accounts require an eligible edition and age 18 or older. |
Why Gemini Stops Working on Windows
The point where Gemini stops responding gives you a clue about what to check. Think back to the last thing that worked, whether that was opening the app, signing in, or using a specific feature.
The App Keeps Running After You Close It
Some users reported in September 2026 that they could open Gemini once, close its window, and then fail to bring it back. Task Manager still showed Gemini, GeminiCrashpadHandler, or Gemini Launcher even though the window had disappeared.
If Gemini opens after you restart your PC but gets stuck again after you close it, look for those processes before reinstalling. Ending them gives the app a fresh start and takes less time than downloading it again.
Another App Owns Alt + Space
On Windows, Alt + Space normally opens the active window’s system menu. Copilot, the ChatGPT companion window, PowerToys Run, and the experimental Google app for Windows can also use those keys.
Startup order and shortcut assignments can affect which app responds, so the same keys may behave differently after a restart. If Gemini still opens from Start, you can work on the shortcut with the app already running.
Your Account or Hardware Is Not Supported Yet
Your work or school account depends on the access your Google Workspace admin has enabled. A personal account can run into restrictions too, including age requirements or controls managed through Family Link.
Some users report that Gemini version 1.10.4 failed to open on ARM64 PCs or crashed on a PC with integrated AMD Radeon graphics. If the window disappears before you can sign in, check the app version and what happens at launch before spending time on your account.
The Feature Is Mac Only for Now
Screen sharing with Gemini and voice dictation into other apps are currently available on the Mac desktop app. The same goes for using Tasks to organize local files into Google Docs or Sheets and opening Google Antigravity with one click.
You can still use the Windows app to draft text, ask coding questions, or upload an image and ask about it. If the rest of Gemini works and you’re looking for one of those Mac features, you can skip the reinstall.
10 Fixes for the Gemini App on Windows
You can start with a browser check and move on to the app, shortcut, or account based on what happens. If you recognize your exact symptom, jump to the fix that deals with it.
1. Check Gemini in Your Browser First
Open gemini.google.com in your browser, sign in with the account you use in the desktop app, and send a prompt. If you get an answer, you can use the same account while you work through the desktop fixes.
If both versions fail, check your connection and account access before reinstalling. Some users reported Gemini web failures on October 9 and 10, 2026, and you can check the Google Workspace Status Dashboard for service notices. If Gemini says something went wrong, check whether the message follows the same account across both versions.
2. End the Leftover Gemini Processes
Press Ctrl + Shift + Esc to open Task Manager. Look for Gemini, GeminiCrashpadHandler, and Gemini Launcher, then select End task for each one you find.
Open the Start menu, search for Gemini, and try launching it again. If ending the processes doesn’t help or they keep coming back, restart your PC and try opening Gemini from Start after Windows loads.
3. Install the Latest Update
Open Gemini and look in the bottom-right corner for an update notice. If you see Restart to update, select it and let Gemini close and reopen so it can install the update.
This is worth trying if you’re still on version 1.10.4 and your symptoms match the reported ARM or Radeon crashes. If Gemini closes before you can reach the update notice, use the reinstall steps below to get a fresh installer from Google.
4. Open Gemini From the System Tray
Look for the Gemini icon in the system tray near the clock and click it to open the app. You can also open Gemini from its taskbar icon if you already have it there.
If you can open Gemini from Start, pin it to the taskbar so you have a way in even when Alt + Space fails. Try opening it from the pinned icon after you close the window to see whether the problem affects the shortcut or the whole app.
5. Change the Gemini Keyboard Shortcut
Open the preferences inside Gemini and look for the shortcut that opens the app. Some users report finding it by right-clicking the Gemini tray icon and opening the General page, so try there if you can’t spot it from the main window.
Choose keys that your other apps don’t use, then test them while you’re working in another window. Some users report that a custom shortcut can fail too, so keep the tray or taskbar icon handy if changing the keys gets you nowhere.
6. Turn Off Alt + Space in Copilot, ChatGPT and PowerToys
Open Copilot in full view, select Account, and look in its preferences for the Alt + Spacebar toggle. In ChatGPT, open the App preferences and find Companion window hotkey. For PowerToys, open PowerToys Run and change Activation shortcut.
Check whether you also have the experimental Google app for Windows, which uses Alt + Space. Restart the apps whose shortcuts you changed so they register the new keys, then test Gemini. If you’re still dealing with Microsoft Copilot not working or ChatGPT not working, open the affected app directly and see whether the trouble goes beyond its shortcut.
7. Fix a Sign-In That Ends on the Website
Some users report completing their work sign-in in a browser, only to land on the Gemini website. If the browser asks Open Gemini?, allow it to open the desktop app, then check whether your Google Account appears in Gemini.
If you keep landing on the website, sign out and start the sign-in again from the desktop app. You can also try temporarily making Chrome or Edge your default browser and repeating the sign-in. If the app opens with basic chat and your saved chats are missing, check whether you’re still signed out.
8. Ask Your Admin to Turn On the Gemini App
If you see Can’t access this service on a work or school account, ask your Google Workspace admin to check your access. Your admin can open Generative AI, select Gemini app, and check Service status for your account. Changes can take up to 24 hours to reach you.
For a work account, you need an eligible Workspace edition and must be at least 18. If the message appears on a personal account managed through Family Link, check with the person who manages the account to see whether Gemini has been turned off.
9. Update Your Graphics Driver
Some users report a crash on integrated AMD Radeon graphics with the message GPU process isn’t usable. If you see that message, check for a graphics driver update from your graphics manufacturer or through Windows Update, then restart the PC and try Gemini again.
If the crash persists, you can try a clean graphics driver install and send Google feedback with the exact error and your app version. If Windows Update itself gets in the way, follow the steps for a Windows 11 update stuck or failing before trying again.
10. Do a Clean Reinstall
Open the Windows Apps page, select Installed apps, and use the three-dot menu beside Gemini to uninstall it. Restart your PC, then get GeminiSetup.exe from the official Gemini download page. Google distributes the installer through that page.
Run the installer and follow its prompts. If SmartScreen or User Account Control asks you to confirm, check that you’re opening the installer you just downloaded from Google. Launch Gemini from Start and sign in with your usual Google Account to bring back your saved chats.
Notes for ARM PCs and Windows 10
Google lists both ARM64 support and Windows 10 compatibility. If you’re on an ARM laptop or an older Windows PC, check the details for your machine before deciding what to try next.
Snapdragon and Other ARM Laptops
Some users report that the launch build, version 1.10.4, wouldn’t open on Windows on ARM. Google now lists ARM64 alongside x64, so try the latest installer if you’re using an early copy on your Snapdragon laptop.
If you already have the latest app you can get and it still won’t open, try Gemini on the web with the same account. You can install the site as an app if you want a separate window while you deal with the desktop launch problem.
Windows 10 Machines
Google lists Windows 10 as a supported version for Gemini. Check that your PC has at least 8 GB of RAM and 200 MB of free space, especially if you’re installing the app on an older machine.
If an update is waiting in Gemini, let the app install it and reopen before testing the shortcut again. If it still won’t start, try Gemini in your browser to see whether you can keep working from there.
If Gemini Still Will Not Open
If the browser works and the desktop app keeps closing, you can give Gemini its own window through Chrome. You can also send Google the details of the failure while they’re still fresh.
Install the Web Version as an App
In Chrome, open gemini.google.com and select the three-dot More menu. Choose Cast, save, and share, then Install page as app. You can also use the install icon in the address bar if Chrome shows one.
Sign in with the same Google Account you use in Gemini for Windows. Your saved chats and memory sync across desktop, web, and mobile, so you can pick up the conversation from the web app.
Send Feedback to Google
Use the feedback option in Gemini or send feedback from the web version if the Windows app won’t stay open. Include your Windows build, Gemini version if you can see it, and what happens when you launch from Start or the tray.
You can also post in the Gemini Apps Help Community. Describe the point where it fails, such as after you close the first window or after your browser finishes signing you in, and include the exact error if you saw one.
How to Keep the Gemini App Running Smoothly
Once Gemini opens again, you can make it easier to tell which app will respond when you press a shortcut. Start with the apps that share Alt + Space, then check which ones load when you sign in to Windows.
Keep One App on Each Shortcut
Pick the app you want on Alt + Space and give any other assistants their own keys. Test each shortcut with another window active so you can see which app actually opens.
If the wrong app starts appearing again after an update, check the shortcut assignments in the apps you use. You can open Gemini from its taskbar icon while you sort out the overlap.
Control What Starts With Windows
Open the Windows Apps page and select Startup, then turn off automatic startup for any assistant you prefer to open yourself. You can also do this in Task Manager under Startup apps by selecting the app and choosing Disable.
The next time you sign in to Windows, try your Gemini shortcut before opening the other assistants. If it works until you launch one of them, check that app’s shortcut assignment.
