Google Put Gemini on Every Windows PC Thursday. Decide Which Account Signs In.

Google released a Gemini desktop app for Windows 10 and 11 yesterday, and it went out worldwide, not a slow rollout to a few countries first. You hit Alt and Space and Gemini opens in a little window sitting on top of whatever you're already looking at. A quote, an invoice you're second guessing, a spreadsheet, a customer email you've been avoiding since Monday. It looks at what's in front of you and answers about it.

The Mac version has been out since April, so the app itself isn't new. What's new is that it just landed on the operating system almost every office around here runs on.

The screen people click past

The download takes about a minute and nobody has to ask permission. That part's fine. The part worth paying attention to comes right after, where it asks which Google account you want to sign in with, and whether it can get at files stored on your computer.

That's what somebody at your shop is going to click through at 8:40 in the morning while they're still holding coffee and half listening to a voicemail.

If the account they pick is the business Gmail, Gemini now has a line into whatever is sitting in that inbox and that Drive. Customer lists. Old quotes with your real margins on them. The W-9s you asked people to email over. A payroll spreadsheet somebody named "final final." None of that got put there with an assistant in mind, because back when it got filed there wasn't one.

I'm not telling you to block it

I've been running the Mac version since spring and the Alt Space thing is useful, especially for anyone who lives in email all day. Pull up a customer thread that's gotten forty messages long, hit the shortcut, ask what they're actually asking for and what you still owe them. Thirty seconds. Do that four times a week and you've got an hour back.

What I'd do is get out in front of it before somebody installs it on their own and makes the call for you.

1: Decide which account it signs into. If you've got a personal Gmail and a business one, this is the week to keep them apart for real. 2: Decide whether it gets to see local files at all, because most of what people want out of it day to day works fine without handing over a look at the whole hard drive. 3: Tell your team out loud that it exists. The ones who don't hear it from you are the ones who'll go searching and install something that looks close enough.

That last one isn't paranoia. Every time a big free tool launches there's somebody putting up a fake download page and buying ads against the name. Go to Google's site, grab the real link, and send it to your people yourself so nobody has to guess.

You may end up with two of these

Microsoft has been pushing Copilot on Windows for a couple of years and most small businesses I sit with either ignore it or forgot it was on the machine. Google just walked onto that turf with something that's easier to reach than Copilot is. So you could wind up with two assistants installed on the same computer, signed into two different accounts, both quietly holding whatever the person at that desk has been working on.

Messier than most owners realize, and a lot cheaper to sort out now, while it's one app on a few machines, than in eight months when everybody's got their own setup and nobody remembers what they clicked yes to.

Take twenty minutes this week. Write down which assistant your shop uses, which account it signs into, and what it's allowed to look at. One page. It's the same thing I have people do in every workshop I run, and it's still the cheapest hour a business owner can spend on this stuff.
