limits / the four walls
It will never do these.
Not promises of politeness - refusals enforced by the code paths themselves, each one covered by tests. The stillness of this page is deliberate.
No. OutOS the OS is not released - no beta, no image, no dates. What you can download is a Windows guided installer that writes an Ubuntu 26.04 live USB safely. That is the first real artifact of the project, and the only one.
Because the scripts are unsigned - there is no EXE and no signing certificate yet. SmartScreen is doing its job. The trade: everything is plain text. Read the launcher and the PowerShell scripts before running them.
The writer refuses any disk Windows marks as boot or system, refuses non-USB bus types, refuses disks larger than the removable range, and refuses any serial that does not match what you typed. All four refusals are covered by tests, and the write path was validated on real hardware. Nothing protects against typing the serial of the wrong USB stick on purpose - read what you type.
Assume no. Pairing keys do not migrate from Windows to a live Ubuntu session. Preflight flags this, and the staged checklist repeats it: have a wired or 2.4 GHz keyboard ready before you restart.
An engineering build for testing the installation experience: no auto-update, no telemetry, no AI features, no signing. It also means these pages mark every capability as proven, in-build, or planned - and a claim without evidence does not get printed.
