Hermès Bélusca-Maïto b299049410 [USERINIT] livecd.c: Change default actions in unattended mode, or if the installer cannot be found (#9363)
- Just after initially caching the path to the ReactOS installer, check
  whether an unattend.inf file can be found in its directory; otherwise,
  fall back to an unattend file in the current ReactOS directory.

- If this unattend.inf file specifies to run an unattended setup
  (`UnattendSetupEnabled` value set to `"yes"`), automatically start the
  ReactOS installer -- instead of starting the live environment desktop.

- If the user presses Ctrl+Shift+F10 however, disable unattended setup
  (suggestion to override the behaviour with a keypress from Whindmar Saksit).

NOTE: in the `WM_INITDIALOG` dialog handlers, use `SendMessageW`
to simulate the button presses. This also allows the invocation
of `EndDialog()` (from the button command handlers) while the
`WM_INITDIALOG` message is handled, so that the USER dialog manager
can then directly close the dialog without showing it first.

========================
ReactOS™ Version 0.4.x
Updated October 9, 2021
========================

1. What is ReactOS?
-------------------

ReactOS™ is an Open Source effort to develop a quality operating system that is
compatible with applications and drivers written for the Microsoft® Windows™ NT
family of operating systems (NT4, 2000, XP, 2003, Vista, 7).

More information is available at: https://reactos.org


2. Relationship with the WINE project
-------------------------------------

ReactOS has always intended to work with the WINE project to share as much
programming effort as possible. This mainly concerns User Mode DLLs and
still happens to a degree today. Other areas of cooperation lie in
applications and testing suites.


3. Future compatibility
-----------------------

The ReactOS project, although currently focused on Windows Server 2003
compatibility, is always keeping an eye toward compatibility with
Windows Vista and future Windows NT releases.


4. Supporting other System Applications
---------------------------------------

The Windows NT architecture allows for subsystems, as does the ReactOS
architecture. A subsystem is an implementation of the APIs of another
operating system, allowing ReactOS to run applications from other systems.
We are already looking at subsystems for: Java, OS/2, and DOS and possibly
others in the future.


5. Is ReactOS legal?
--------------------

Yes we are.
All the code of ReactOS has been written from scratch by our developers.
We go to great lengths to ensure that the code our developers create is clean,
same applies to the variety of methods we use to understand Windows internals,
including clean room reverse engineering, using existing documentation freely
available both in books and on the web, using extensive tests (tens of millions)
which apply black box engineering methods against both public and private APIs
exposed by the operating system.


6. Tutorials
------------

Developer and User Tutorials: https://reactos.org/wiki

The tutorials contain more information on the project, compiling and testing
ReactOS - amongst other topics. Contributors to the project are always welcome.


7. Frequently Asked Questions
