 ===== What is WSL ? =====
-Useful reading:
+//Windows Subsystem for Linux// (**WSL**) lets you **run a Linux distribution on your Windows computer**, without the overhead of a traditional virtual machine (VM) or dual-boot setup
-  * Have a look at the beginning of the [[https://docs.microsoft.com/en-us/windows/wsl/about|Windows Subsystem for Linux Documentation]] for a quick **WSL** description on the Microsoft site
-  * Read [[https://wiki.ubuntu.com/WSL|What is WSL]] on the Ubuntu site
-    * There is more useful information on the //WSL@Ubuntu page//, you can read the rest later
-In a few words, WSL is not Linux, it's more a way to [[https://blogs.msdn.microsoft.com/wsl/2016/06/15/wsl-file-system-support/|share files between Windows and Linux]] (it's OK to skip this rather technical link!). [[https://docs.microsoft.com/en-us/windows/wsl/faq#are-files-in-the-linux-drive-different-from-the-mounted-windows-drive|Files under the Linux root (i.e. /) are controlled by WSL which mimics Linux specific behavior [...follow the link for details...]]]. That's why you need //to activate WSL **and then install a Linux distribution**//.

 ===== Prerequisites =====
-  * A computer running at least //Windows 10 Anniversary Update//, that is with a version number of ''1607'' (July 2016) or higher
+==== Windows version ====
+  * A computer running [[https://docs.microsoft.com/en-us/windows/wsl/install-manual#step-2---check-requirements-for-running-wsl-2|Windows 11 or Windows 10, Version 1903, Build 18362 or later]]
     * [[other:win10maintain#checking_the_installed_version|Check the installed version on your computer]]
-    * [[other:win10misc#windows_10_versions|Check the available versions]]
+    * [[other:win10misc#windows_10_versions|Check the available Windows versions]]
-    * [[other:win10maintain#updating_windows_10|See if you can update your Windows]] if your installed version is not the most receent available version
+    * [[other:win10maintain#updating_windows_10|See if you can update your Windows]] if your installed version is not the most recent available version
-      * Note: there is sometimes a delay between the official release and the time when Windows Update will actually tell you that a major update is available for **your** computer (e.g. the //September YY09// update may become available for you only in December)
+==== Computer memory ====
+FIXME
+==== Disk space ====
+FIXME
   * //Enough// space on ''C:\''. Microsoft instructions say //The Windows Subsystem for Linux only runs on your system drive (usually this is your C: drive)//
     * Exporting a //simple// Ubuntu configuration (after doing everything from //Base installation// to //Advanced configuration// below) with the [[other:win10wsl#creating_a_backup_of_the_linux_running_in_wsl|wsl --export]] command generated a 2.7 Gb tar file (uncompressed), so it's probably good to **start with at least 3 Gb of free space on ''C:\''** (and you always need to keep enough free space on ''C:\'' for regular Windows operation)
