 ===== Miscellaneous =====
+==== Updating WSL 1 to WSL 2 ====
+=== Am I using WSL 1 or WSL 2 ? ===
+If you have never used WSL on this computer (and for **this user**), WSL 2 will be installed directly when you follow the [[other:win10wsl#base_installation|Base installation]] steps
+If you are not sure if you are currently using WSL 1 or WSL 2, you can check [[https://github.com/MicrosoftDocs/WSL/issues/1599|Is there an easy (PowerShell?) way to get more information about WSL?]] has been answered, or make the following checks
+  * ''wsl --update'' will give the same output (i.e. the installed Linux kernel version) for both WSL 1 and WSL 2
+    * <code>PS C:\Users\jypeter> wsl --update
+Recherche de mises à jour en cours... Veuillez patienter
+Aucune mise à jour n’est disponible.
+Version du noyau : 5.10.102.1</code>
+  * ''wsl --status'' will display again the kernel version if you already have WSL 2, but will display a link to the WSL installation page if you are running WSL 1: https://aka.ms/wsl2-install
+    * <code>PS C:\Users\jypeter> wsl --status
+Distribution par défaut : Ubuntu
+Version par défaut : 2
+Activez la fonctionnalité Windows de plateforme de machine virtuelle et assurez-vous que la virtualisation est activée dans le BIOS.
+Pour plus d’informations, rendez-vous sur https://aka.ms/wsl2-install</code>
+=== Prerequisites ===
+  * If WSL 1 is already running, you should have no problem with the [[other:win10wsl#prerequisites|disk and memory requirements]]
+  * For WSL 2, you also need to meet the [[other:win10wsl#hyper-v_requirements|Hyper-V requirements]]
+=== Updating! ===
+[[https://docs.microsoft.com/en-us/windows/wsl/install-manual#step-3---enable-virtual-machine-feature|Activate the Virtual Machine Platform]] (just the //Step 3// instructions) and reboot the computer
+After rebooting, go back to the [[other:win10wsl#updating_wsl_1_to_wsl_2|Am I using WSL 1 or WSL 2 ?]] section above, and check that you are now using WSL 2
