When Windows 7 came out, one of the quiet pleasures it introduced was "Aero Snap" — the ability to drag a window to the edge of your screen and have it tile neatly, or use keyboard shortcuts (Win + Left, Win + Right) to do the same thing.
It was such a small feature. And yet, once you'd used it for a week, going back to a computer without it felt tedious. Moving mouse, grabbing corner, dragging, releasing. The keyboard shortcut was so much kinder on the hands.
At the time, a lot of people were still on XP and Vista. Businesses, in particular, were slow to upgrade. So we built Win7Keys: a tiny background utility that added those keyboard shortcuts to older versions of Windows. Ctrl+Alt+1/2/3/4 to snap windows into quadrants. Win+Left/Right to tile. Basic stuff, done well.
This is a little retrospective on that project, and a note about why I still think small free tools matter.
What it did, exactly
Win + Left/Right: tile the active window to the left or right half of the screenWin + Up/Down: maximise or restoreCtrl + Alt + 1/2/3/4: place the window in one of the four quadrantsCtrl + Alt + Home: centre the window
It ran silently in the system tray, used almost no memory, and could be closed with a right-click. That was the entire product surface.
Why it worked
A few things made it more popular than we expected:
Scope was tight. We didn't try to be a "window manager." We tried to port five keyboard shortcuts. That clarity made the product easy to describe, easy to install, and easy to recommend.
Installation was one click. A single EXE. Double-click, done. No installer, no adware, no "also install this free toolbar." This was the Vista/XP era — people had been trained by shareware into deep suspicion. A tool that respected them was unusual.
It was free. We made no money from it. It wasn't even a "try it for free then pay." It was just a thing we built for ourselves and shared. This mattered more than we realised at the time.
It solved a specific, repeated annoyance. Every time you use a keyboard shortcut that doesn't exist, you lose a tiny bit of flow. Solving that hundreds of times a day adds up.
The distribution surprise
We put it on a simple download page, wrote about it on a developer forum, and then — nothing happened for two months. We moved on to other things.
Then a tech blog linked to it. Within a week it had been downloaded 50,000 times. Within a month, half a million. We got emails from all over the world saying "thanks, this made my old work computer feel modern." We got emails from Microsoft engineers saying "nice work." We got exactly one email from a lawyer at a big company politely asking us to confirm we weren't using any Microsoft code (we weren't; we'd written our own window-snap logic from scratch).
What I learned: there is always an audience for a small, free, focused tool that solves a real annoyance. The audience doesn't show up at launch. It shows up when someone with reach finds the thing useful and tells their friends.
Why I think about it often
I've been in this industry long enough to see the pendulum swing. For a while, "developer building small free tools" felt like a natural thing. Then the SaaS era made everyone think every piece of software needed a subscription. Now, between open source, personal projects, and the generative-AI wave making it cheap to build, I think the era of small, free, focused tools is coming back.
Not every piece of software needs to be a company. Not every company needs to be a venture-backed rocket. Sometimes you can just make a thing, put it online, and make a small corner of the world better.
Win7Keys was that, for us. It wasn't a business. It didn't change our trajectory. But a quarter of a million people used it happily for a few years, and we got to meet some of them through kind emails.
A small recommendation
If you've been in this field for a while and you've forgotten how good it feels to ship a small, finished thing for no reason other than wanting it to exist — consider building one. A utility you'd use. A script that solves a particular annoyance. A website about a hobby. Ship it. Put it online. See who shows up.
Win7Keys doesn't run on any modern machine, by the way. It's a historical artefact. Every version of Windows since has included the window-snapping shortcuts natively, which was kind of the point.
If you're building small, warm tools and would like to share them, tell us. We love this kind of thing.
