Global insomnia is lazy engineering. Per-app models reduce forget-to-toggle-off debt—the classic Awake failure mode.

If this sounds like your week
Laptops left awake unintentionally become flat-battery surprises. per application screen awake control windows 11.
Where tooling usually breaks
Foreground-targeted behavior tends to match human intent better.
Scope ladder
Global insomnia → risky on laptops Session toggle → easy to forget Per-app foreground targeting → tighter intent match
Where StayGreen lands
Target the IDE, encoder, installer—whatever justified the vigil—rather than irradiating entire user sessions.

What you get
Holds a documented Windows power request and reacts to system events, instead of a polling loop or simulated mouse movement.
Auto-pauses on battery, when Battery Saver is on, or when the lid closes with no external display attached — and resumes on its own.
Keep awake only when specific apps like `ms-teams.exe` are active.
One-time purchase, perpetual license. Pay once, own it forever on the Microsoft Store.
Engineering Proof
StayGreen holds a Windows power request — created with
PowerCreateRequest and set with
PowerSetRequest — to ask Windows
directly for the awake state. No fake mouse movement, no periodic wake pings, and no loop burning cycles to
pretend the user is active.
It deliberately does not use the older
SetThreadExecutionState flag,
which is thread-affine: the flag belongs to the thread that set it. StayGreen changes its awake state from
several threads — the command handler, the timed-session task, and the Win32 event worker — and a thread-affine
flag produced inconsistent releases. The request API does not have that problem.
A single capture on one PC rather than a benchmark — we publish no averaged CPU or memory figure, because the app ships no measurement harness to produce one.
Product Interface
The StayGreen interface keeps the important decisions obvious: when to override sleep, how long to hold the state, and which app should trigger it. No command-line dance. No clutter disguised as enterprise UX.
Real workflows: focus timers that stay visible, batches that never leave the disk, and renames you can rewind.
PinPoint: Always On Top saves me so much time as I can organize all my report materials without having to flip between windows or tabs. I love the fact that it is straightforward and simple.
I used to get so frustrated when my Taskbar would freeze and disappear. Taskbar Sentinel has eliminated that pain without subjecting me to another subscription.
OpticBatch and MetaForge are a lifesaver for me as a person with a passion for photography. They give me the ability to stay organized and keep personal information confidential when I post pictures online.

FAQ
StayGreen holds a documented Windows power request instead of running a busy loop—per-app rules that follow the foreground window, lid and battery guardrails, and Microsoft Store licensing that stays purchasable instead of cloudy. Respect corporate power policies before rolling fleet-wide.
Hopefully not permanently. Prefer session-scoped posture and per-app rules so notebooks return to sane sleep curves once the risky window closes.
Simulated HID events read as spoofing—Windows flags injected input, so monitoring tools can see it. A power request asks Windows plainly instead, and generates no input at all.
StayGreen stays a straightforward Microsoft Store purchase—no metering tricks for fundamentals.
Use AutomataLabs.ca for narrative context, grab the SKU through Microsoft Store portals for corp billing alignment.
StayGreen holds a documented Windows power request — no fake input, no polling loop — with interlocks that pause on battery, on Battery Saver, and when the lid closes with no display attached, plus per-app rules that follow the foreground window.
