Keep your Windows PC awake: every way that works.
Downloads that die at 2%, presentations that go dark, builds that pause when the lid stays open but the screen doesn't. Windows sleeping at the wrong moment has a dozen fixes — here are all of them, with the trade-offs stated plainly, including the free ones.
1 · Windows power settings (free, built-in, blunt)
Settings → System → Power & battery → Screen and sleep, set “put my device to sleep after” to Never.
- Good: zero software, works forever.
- The downside: it's global and permanent until you change it back — and nobody changes it back. Your laptop now never sleeps, ever, including in the bag on Friday evening. This setting is for desktops that should genuinely never sleep, not for “this afternoon's download”.
2 · powercfg (free, for scripts and admins)
From a terminal: powercfg /change standby-timeout-ac 0 disables sleep on AC power (use standby-timeout-dc for battery). Same effect as method 1, scriptable. Same downside too: it's a switch you must remember to flip back. Useful in deployment scripts; clumsy as a daily driver.
3 · Presentation Mode (free, laptops, presentations only)
On many laptops, Windows Mobility Center (or running presentationsettings.exe) offers “I am currently giving a presentation”: screen stays on, notifications quiet down. Built for exactly one scenario and fine at it — but it's manual, easy to forget on, and desktop PCs often don't have it at all.
4 · PowerToys Awake (free, Microsoft, manual)
Part of Microsoft's PowerToys suite: a tray icon that keeps the PC awake indefinitely, for an interval, or until a set time, with an optional keep-screen-on. If your need is occasional and manual, this is the best free answer — we say so in detail in StayUp vs PowerToys Awake. What it doesn't do: react to why (no per-app rules, no daily schedule, no stay-active), and it comes as part of the full suite.
5 · Keypress simulators (free, old, with side effects)
A family of small old tools keeps Windows awake by simulating a key press (typically F15) every minute. It works — but simulated keypresses go to whatever app has focus, which can interrupt games, remote desktops and full-screen apps in surprising ways, and many of these tools haven't been updated in years. If you go this route, prefer tools that use the Windows power API instead of fake input.
6 · StayUp ($8.99 — when awake is part of how you work)
StayUp uses the documented power API (no fake input in its main mode) and adds the layer all the above lack: intent.
- Durations that match real life: forever, 30m, 1h, 2h, or “until 18:00” — one tap, then the PC goes back to normal by itself.
- Per-app rules: awake while Zoom, OBS or your backup tool is running. Stands down when they close.
- A daily schedule, including overnight ranges for night jobs.
- Stay active (optional, off by default): a 1-pixel nudge when you're idle keeps idle-based status dots accurate while you step away. It's synthetic input, which Windows flags as such.
- A hotkey and a tray icon that glows while it's holding the door open.
Which one should you use? Desktop that must never sleep → method 1 and done. Occasional manual need and you like free → PowerToys Awake. Keeping the PC awake is part of your daily work — meetings, recordings, downloads, presence — and you want it automatic and reversible → that's the job StayUp was built for. $8.99 once, 2 PCs, 14-day refund.
