-==== Computer memory ====
+==== The basics before starting ====
-FIXME
+Once you have verified that your Windows is recent enough, you should also:
+  * Install the [[other:win10apps#windows_terminal|Windows terminal]], because it will be one of the ways to open ''Ubuntu'' terminals, once ''Ubuntu'' is installed
+  * Have at least some basic knowledge of Linux...
+    * Get some [[other:newppl:starting#useful_documentation_for_beginners|basic Linux documentation]] if required
+==== Computer CPU and memory ====
+Contrary to other virtual machines, WSL is well integrated with the Windows operating system and the hardware drivers and has a very low default CPU and memory footprint!
+  * You should be able to play with WSL even with 8 Gb of RAM, but 16 Gb is recommended
+  * Of course, depending on what you need to do on your computer, a better processor will always help
+  * WSL+Ubuntu will use more CPU and RAM if you use it for running CPU and/or memory intensive processes! As would be the case with any Windows application... :-)

-  * The steps below will work if you have //Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11//
+  * The steps below (based on [[https://docs.microsoft.com/en-us/windows/wsl/install|Install Linux on Windows with WSL]]) will work if you have //Windows 10 version 2004 and higher (Build 19041 and higher) or Windows 11//
-    * If you have an older Windows version, follow the [[https://docs.microsoft.com/en-us/windows/wsl/install-manual|Manual installation steps for older versions of WSL]]
+    * If you have an older Windows version (at least //Version 1903, Build 18362//), follow the [[https://docs.microsoft.com/en-us/windows/wsl/install-manual|Manual installation steps for older versions of WSL]]
+  * Open a ''Powershell'' in //administrator// mode
+    * ''Start''=>''W''=>''Windows PowerShell'' then right-click on ''Windows PowerShell'' and select //Run as Administrator//
+    * Use a [[https://wiki.lsce.ipsl.fr/pmip3/doku.php/other:win10apps#windows_terminal|Windows Terminal]], if you have already installed it. Use ''CTRL''+<left click> on ''Windows Powershell'' in the pull-down menu to get a ''Powershell'' in //administrator// mode
-  * Follow **closely** the steps listed in [[https://docs.microsoft.com/en-us/windows/wsl/install-win10|WSL Windows 10 Installation Guide]]. <wrap hi>Open this [[https://docs.microsoft.com/en-us/windows/wsl/install-win10|WSL Windows 10 Installation Guide]] in another window, so that you can **read the useful hints below at the same time!**</wrap>
+  * Determine which Linux distributions are (directly) available for installation.\\ We will use the default ''Ubuntu'' distribution
-    * When you have to //Open PowerShell as Administrator//, go to ''Start''=>''W''=>''Windows PowerShell'' then right-clik on ''Windows PowerShell'' and select //Run as Administrator//
+    * ''Ubuntu'' will always automatically upgrade to the latest ''LTS'' release available (contrary to ''Ubuntu-<even_number>.04'' that will stick to the specified ''<even-number>'' release)
-    * FIXME At this stage, we could try to restore/clone a previously installed/customized/backed-up version of Ubuntu if we have one (see [[other:win10wsl#restoring_a_wsl_backup|Restoring a WSL backup]])
+    * We could specify a specific Linux version (or even [[https://docs.microsoft.com/en-us/windows/wsl/use-custom-distro|import any Linux distribution]], or [[https://docs.microsoft.com/en-us/windows/wsl/build-custom-distro|create a custom Linux distribution]]!)
-    * In the //Install your Linux Distribution of Choice//, we will use the very easy //install from the Microsoft Store// option
+    * <code>PS C:\> wsl --list --online
-      * Open the **Microsoft Store** with: ''Start''=>''Microsoft Store''
-      * In the **Microsoft Store**, just search //Linux// and select the //generic// **Ubuntu** (select the //Ubuntu// that has **no version number after the name**)
+  NAME            FRIENDLY NAME
-      * Select ''Get'' (''Télécharger'') to download the installer package. You can ignore (''No thanks'') the popups asking you to use a Microsoft account, if you are not using a Microsoft account yet on this machine
+* Ubuntu          Ubuntu
-      * Select ''Launch'' (''Lancer'') to start the installation, and give a user name (e.g. your LSCE login) and password (something that you can remember, but maybe not the same password as your LSCE account)
+  Debian          Debian GNU/Linux
-      * Type some basic Linux commands to check that things are working, e.g. check the available disks\\ <code>$ df -h
+  kali-linux      Kali Linux Rolling
+  openSUSE-42     openSUSE Leap 42
+  SLES-12         SUSE Linux Enterprise Server v12
+  Ubuntu-16.04    Ubuntu 16.04 LTS
+  Ubuntu-18.04    Ubuntu 18.04 LTS
+  Ubuntu-20.04    Ubuntu 20.04 LTS</code>
+  * Install the latest //Ubuntu LTS// version available\\ This step will run pretty quickly\\ <code>PS C:\> wsl --install -d Ubuntu
+Installation en cours : Plateforme de machine virtuelle
+Plateforme de machine virtuelle a été installé.
+Installation en cours : Sous-système Windows pour Linux
+Sous-système Windows pour Linux a été installé.

+Installation en cours : Noyau WSL
+Noyau WSL a été installé.
+Téléchargement en cours : Ubuntu
+L’opération demandée est réussie. Les modifications ne seront pas effectives avant que le système ne soit réamorcé.</code>
+  * Reboot the computer and be patient
+    * This step will take some time (make sure you have 15-30 mn available). Windows will install and configure what it needs for running //WSL+Ubuntu//, reboot, and install some more //stuff//
+    * The final installation step will take place when you open your Windows session. A terminal opens, displaying the final installation of Ubuntu, and asking you for a username and password, and giving you access to a ''bash'' prompt
+    * <code>Installing, this may take a few minutes...
+Please create a default UNIX user account. The username does not need to match your Windows username.
+For more information visit: https://aka.ms/wslusers
+Enter new UNIX username: stdu
