PrisnovaOS
Your desktop, cut from light
A prism-themed desktop shell for Windows. PrisnovaOS replaces the taskbar with its own dock, frames your desk with world clocks, weather, system vitals and quick notes, and splits light across live wallpapers in five inks from Spectrum to Verdant. A command palette finds any app in a keystroke, and everything runs on your PC with no account and no telemetry.
Previously released as HSX PrisnovaOS.
£11.89 on the Microsoft Store (UK), with a free trial firstPrice checked 22 October 2026. Prices differ by country; the Store shows yours.

Your first hour with PrisnovaOS
A short plan for getting to a real result while the trial is still running.
Start the free trial
Get PrisnovaOS from the Microsoft Store. The Store page shows how long the trial lasts, so you know your window before you begin.
Use your own work
Try it on your own PC and real tasks rather than a quick look around. That is the only test that tells you whether it earns its place.

Decide before it ends
If it earned its place, buy it on the Microsoft Store before the trial runs out. The purchase unlocks the copy you already have, so there is nothing to reinstall.

Who it is for
PrisnovaOS is built for people who want a Windows desktop that looks and works the way they choose, without a shell that reports on them.
It sits in the desktop shells & customisation part of the catalogue, and your documents never leave the machine to be processed. There is no server behind PrisnovaOS to send them to.
Local-first, by design
Plenty of the alternatives send your documents to a server to be handled. PrisnovaOS does not. Processing runs on your CPU or GPU, and the documents you open stay where you put them. The application keeps working with the network switched off.
That is not a setting you enable, it is how PrisnovaOS is built, which is why there is no account to create and no subscription to lapse. Full detail is in the PrisnovaOS privacy policy.

No. There is no registration, no sign-in and no online identity. You install the application and use it.
