DexTor OS for Windows v0.1.40

Fixes from the first round of testing, an end-user license that allows commercial use, and QEMU
from DexTor's own mirror.

Highlights

• EULA for the release builds. Using the official launcher - personally or commercially, by
  people and by organizations - is covered by EULA.md, attached to this release. The source code
  stays under the PolyForm Strict License 1.0.0. The installer links the EULA and asks you to
  accept it.
• QEMU from DexTor's mirror. The launcher now downloads Stefan Weil's QEMU for Windows
  installer, unchanged, from
  dextoros/qemu-runtime,
  with qemu.weilnetz.de as a fallback, and accepts it only with the same pinned SHA-512. The mirror
  release carries the corresponding source code, and THIRD-PARTY-NOTICES.md now includes a
  written offer for it.
• Remembers your language. The language picked in the launcher is used again on the next start.

Fixes

• Restarting from inside DexTor OS restarts it in the same window, behind the DexTor splash,
  instead of switching the virtual machine off and reporting that it stopped unexpectedly. A guest
  that keeps restarting (three times within a minute) is stopped and reported.
• Shutting DexTor OS down from inside it is shown as "DexTor OS was shut down", not as an error.
• Changing the language while DexTor OS runs no longer replaces its status card, and the main
  button keeps doing what it says.
• The Ready screen now describes both modes of DexTor OS: Guest mode erases data at shutdown;
  Secure mode keeps it encrypted on the USB drive. In all 10 languages.
• After an uninstall, the installer says the launcher was removed instead of "Setup complete".
• While the drive is written, the old edge of the progress card no longer stays drawn over the
  speed chart.
• The welcome screen gives the current download size, 1.8 GB.
• The launcher's window and its file have a sharp icon at every size.

Download

DexTorOS-Portable-0.1.40-win-x64.exe - one portable file, no installation and no separate .NET
needed. Requires Windows 11 x64. It was built from exactly the source code of this release
with build-portable.bat 0.1.40 and .NET SDK 10.0.401.

This is a beta build and it is not code-signed yet, so Windows SmartScreen warns about an
unknown publisher. Check the file before running it (see "Verify a download" in the README):

DexTor OS for Windows v0.1.39

The first public release of the DexTor OS for Windows launcher - and the first time its full
source code is published.

What it does

• Turns a USB drive of 8 GB or more into a DexTor OS drive that boots on a compatible PC and
  also runs inside Windows 11, in its own window.
• Checks this PC first and changes nothing while checking: Windows version, memory, disk space
  and virtualization.
• Downloads the latest DexTor OS image and resumes interrupted downloads. Before anything is
  written, it verifies the signature of the published SHA-256 with its release key and checks the
  image against that hash.
• Asks before erasing, showing the drive letter, model and size. Refuses system, boot, read-only
  and non-USB disks.
• Writes the image without the Windows cache, then reads it back from the stick and verifies it
  before the drive is marked ready.
• Starts DexTor OS inside Windows on a pinned, verified QEMU with the Windows Hypervisor Platform,
  sized to the computer. The boot is shown as steps behind a DexTor splash, and the window opens
  maximized on the launcher's monitor, at that monitor's resolution, once the guest has drawn its first frame.
• Gives DexTor OS one private data.img on the stick in both modes, for its LUKS-encrypted
  storage, and never runs two DexTor sessions on the same storage at once.
• Speaks 10 languages and hands the selected one to DexTor OS.
