Keep Slack active on Windows
Slack's green dot is meant to tell your team you are around. In practice it tells them whether you have touched your PC in the last ten minutes. Read a long doc, take a call on your phone, or think something through on paper, and the dot goes hollow.
Here is how Slack decides, why the obvious fixes do not hold on Windows, and what does.
How Slack decides you are away
Slack sets you to away "after 10 minutes of desktop inactivity", and on mobile as soon as you leave or close the app (Slack Help Center: Set your Slack status and availability). Slack's developer documentation says the same from the server side: after 10 minutes with no activity in the client, the user is automatically marked as away (Slack developer docs: User presence and status).
"Activity" on Windows means keyboard and mouse input. Slack cannot see you reading; it sees the Windows idle timer climbing. This is the same whether you use the Slack desktop app from the Microsoft Store, the installer from slack.com, or Slack in a browser tab.
Why "Set yourself as active" does not hold
Under your profile picture, Slack offers Set yourself as away and Set yourself as active. Away is a manual override that holds. Active only switches you back to automatic mode, where the 10-minute rule applies again. Slack's developer docs put it plainly: "there's no way to force a user status to active" (Slack developer docs).
That is also why browser extensions or cloud services that keep Slack "active" through the API cannot pin you either. They can only keep you on automatic, and automatic still depends on activity on your PC.
Why PowerToys Awake and power settings do not help
PowerToys Awake keeps your PC (and optionally the screen) awake, but it does not create input (Microsoft Learn: PowerToys Awake). Longer screen and sleep timeouts under Settings > System > Power & battery (Windows 11) or Power & sleep (Windows 10) do the same (Microsoft Support). Your screen stays on, and Slack still marks you away at ten minutes, because nothing reset the idle timer.
The free fixes worth trying first
- Use a status instead of the dot. A Slack status like "Reading the Q3 spec, back in 20" or "On a call", with an expiry, tells people more than a green dot.
- Keep Slack open where you type. Slack counts activity per client. Your phone will not hold your status on its own, because mobile goes away as soon as the app is in the background.
- Lengthen screen and sleep timeouts, if your workplace allows it. That stops the PC from locking or sleeping on you, but not the 10-minute rule.
What actually keeps Slack active
Something has to reset the Windows idle timer. Free input tools such as Caffeine for Windows and Move Mouse do that, and so do USB jigglers, each with trade-offs. We compare them honestly in a mouse jiggler alternative for Windows.
Full disclosure: Stay Green is our app. It lives in the system tray on Windows 10 and 11 and only steps in once you have really been idle for a few minutes. Then it sends one F20 keypress, a key standard keyboards do not have and that does nothing visible. Windows counts it as input, the idle timer resets, and Slack stays active. So do Teams, Zoom and Discord, since they read the same timer. Your cursor never moves.
It pauses itself outside your work hours (9 to 5 by default, adjustable) and during an optional lunch break, so you do not show as active at midnight, and it relaxes when it notices you are on a call. Nothing about what you type or do leaves your PC: the only network traffic is an update check and a license check.
There is a 14-day free trial, no card needed, and one license works on a Mac or a PC. The installer is not code-signed yet, so on first run Windows may show "Windows protected your PC"; click More info, then Run anyway.
Honest caveats
- A locked PC shows you away in practice, because there is no input reaching Slack. Leave your company's lock policy alone.
- Slack on your phone does not help. Mobile goes away whenever the app is in the background.
- Check your workplace policy. Some employers have rules about activity simulation. Use any of these tools to cover genuine work away from the keyboard, not to appear to be working when you are not.
FAQ
How long before Slack marks me away on Windows?
Ten minutes without desktop activity (Slack Help Center). Teams is stricter, at about five minutes; see Teams goes Away after 5 minutes on Windows.
Can I make Slack always show me as active?
Not through Slack itself. "Set yourself as active" returns you to automatic presence, which depends on activity (Slack developer docs).
Will PowerToys Awake keep me active in Slack?
No. It prevents sleep but creates no input, which is what Slack checks.
Does the same apply on a Mac?
Yes. See Slack shows you inactive after 10 minutes and keep Slack green on Mac.
