Mouse jiggler for Windows 11: stopping the lock screen
Windows 11 locks the screen on a timer your IT team set, and the usual fixes are greyed out. The gap is not power settings — it is input.

Why the usual fixes are greyed out
On a managed laptop the screen timeout and the lock timer come from Group Policy, so the sliders in Settings are missing, disabled or quietly reset minutes later.
Power settings hold the screen, not the input
Even when editable, power options only decide when the display sleeps. Trackers and Teams or Slack presence read the input stream, so a lit screen with no keystrokes still counts as idle.
- Screen timeout: the display only.
- Lock and idle timers: input events.
- Presence: time since the last input.
What simulated input does instead
A presence app supplies the events: smooth mouse paths, navigation keys in a living rhythm, scrolling and window switching. No policy is touched — the machine simply stops going quiet.
Reaction
Mouse jiggler
- Starts only when the computer is idle.
- Gives control back at your first mouse move.
- Varied timing, not a fixed loop.
Where the limit still is
If your policy blocks installing software, that restriction holds: Reaction is an ordinary desktop app and installs like any other. It changes what the computer reports, not what your company permits.
In short
The lock timer watches input, not the screen — and input is the one part still in your hands.
Let Reaction hold the number for you
Set your activity band, turn on hidden mode, and Reaction keeps a natural, human-like level while you are away — and hands control back the moment you return.
FAQ
Why is my mouse jiggler not working on Windows 11?
Single-pixel loops are often filtered out by pointer settings or a remote session.
Can I change the lock screen timeout myself?
On a personal machine yes; on a managed laptop Group Policy overwrites the value.
Does keeping the screen awake stop the idle status?
No, those timers measure time since the last keyboard or mouse event.
