Rust-native framing matters because keep-awake tools should not spin CPUs to pretend they are working.

If this sounds like your week
Low overhead is not a slogan—it is whether your utility silently burns watts doing nothing. keep screen awake per app windows 11 low cpu 2026.
Where tooling usually breaks
If keep-awake makes the machine feel busy, something is wrong.
Overhead contrast
Busy loop / fake input → watts + surprises Execution state API → ask OS honestly StayGreen → low-overhead keep awake posture
Where StayGreen lands
Rust-flavored ergonomics prioritize honest idle charts over fake activity loops.

What you get
Uses Windows execution-state calls instead of polling loops or fake input.
Auto-pauses when the charger is unplugged or the lid is closed for safer thermal and battery behavior.
Keep awake only when specific apps like `ms-teams.exe` are active.

Engineering Proof
StayGreen uses SetThreadExecutionState to request the awake state directly from
Windows. That means no fake mouse movement, no periodic wake pings, and no background loop burning cycles just to
pretend the user is active.
For technical buyers, this is the whole point: the operating system does the work, while StayGreen simply sets the appropriate execution-state flags and gets out of the way. In our idle tests, Task Manager reports roughly 0.0% CPU usage with a memory profile under 8 MB for the keep-awake path.
Screenshot evidence for the low-overhead runtime profile.
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.
Trusted by pragmatic desktop users
Real workflows: focus timers that stay visible, batches that never leave the disk, and renames you can rewind.

FAQ
StayGreen leverages Windows execution-state semantics with effectively zero synthetic busy loops—per-app targeting, lid/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—they spook SOC tooling, distract humans, waste watts. Execution-state semantics ask Windows plainly when attention is warranted.
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 uses Windows execution-state calls with effectively zero CPU overhead, smart lid/battery interlocks, and per-app targeting when you need the machine to stay present for real work.
