-  WSL2 (Windows Subsystem for Linux 2) runs a true Linux kernel via Hyper-V emulation.
+  WSL2 (Windows Subsystem for Linux 2) runs a true Linux kernel via Hyper-V virtualization.

+## Read Carefully!
+
+1. WSL is a **system** service which **requires Admin privileges** to install.
+2. A **System Reboot** is required **inbetween** install steps.
+
 ## Cheat Sheet
 
 > WSL 2 uses `VirtualMachinePlatform` and Hyper-V to run a full Linux kernel
-> with 100% syscall compatibility.

+**Most people** want [WSL 1 + WSL 2 + Linux](https://webinstall.dev/wsl). \
+(WSL 2 is NOT a replacement for WSL 1, it's just another _layer_ of WSL)
 
-### Admin Privileges Required
+See the **Full Cheat Sheet** at <https://webinstall.dev/wsl>.
 
-It is not possible to install WSL without Admin privileges.
+### How to Install Linux
 
-You _will_ need to allow the installer to run as Admin when asked.
+Once WSL is installed you can download Linux from the Windows Store. We
+recommend:
 
-### Reboot Required

-You will not be able to use WSL without rebooting.

-### Switching Between WSL and WSL 2
+### How to Switch to WSL 2 Manually
 
-After rebooting you can set WSL 2 as the default:
+To set WSL 2 for a specific Linux installation:
 
-```pwsh
-wsl --set-default-version 2
-```
+1. List all installed Linux versions
+   ```pwsh
+   wsl --list --verbose
+   ```
+2. Set the desired version to WSL 2 with `--set-version`. For example:
+   ```pwsh
+   wsl --set-version Ubuntu-20.04 2
+   ```
 
-You can list your existing WSL Linuxes:
+If WSL 2 works on your computer, you may set it as the default:
 
 ```pwsh
-wsl --list --verbose
-```
-
-And you can switch between using WSL and WSL 2 without an issues:
-
-```pwsh
-wsl --set-version Ubuntu 2
+wsl --set-default-version 2
 ```

+
+It may be that your computer does not support virtualization because:
+
+- it lacks hardware support in the CPU for VTx
+- VTx is disabled in the BIOS or EFI
+- Virtualization has disabled in Windows 10
+
+You should switch back to WSL 1 until you solve this problem:
+

+wsl --set-default-version 1
+wsl --list --verbose
+wsl --set-version Ubuntu-20.04 1
