 ### Docker System Requirements
 To install Docker, you have to have all of the following.
 
-* Virtualization enabled in your laptop's BIOS. See the documentation from your manufacturer for this step.
-* Windows 10 64-bit: Pro, Enterprise, or Education (Build 15063 or later).
-* Enable the Hyper-V and Containers features for Windows 10 Professional.
+1. Windows 10 64-bit: Pro 2004 (build 19041) or higher, or Enterprise or Education 1909 (build 18363) or higher.
+2. The following hardware prerequisites are required to successfully run Client Hyper-V on Windows 10
+   - 64 bit processor with Second Level Address Translation (SLAT)
+   - 4GB system RAM
+   - BIOS-level hardware virtualisation support must be enabled in the BIOS settings. See the documentation from your manufacturer for this step. For more information, see Virtualization: <https://docs.docker.com/docker-for-windows/troubleshoot/#virtualization-must-be-enabled>
+3. Enabled ```Hyper-V and Containers features```for Windows 10.
+
+**Note:** *Above system need can change with newer docker desktop versions.More on requirements, check: <https://docs.docker.com/desktop/windows/install/>.*
+
+ *You can also download the script:<https://raw.githubusercontent.com/fnproject/cli/cli_fn_windows_install/fn_windows_installer.ps1> locally and place it at location(```c:\fn_install\```) and execute in below way to see the current system state and see whether it is meeting the above need, otherwise Docker desktop will not work properly.*

+- If just above step is showing that ```Hyper-V``` is not enabled then you can run command in opened PowerShell. This will enable the ```Hyper-V```. 
+  This step may result in system restart, please do follow the steps below post restart.

 ## Install Fn Client
-There are three ways to install the Fn client on Windows.
-
-### (1) Windows 10 Quick and Dirty
-* Go to: <https://github.com/fnproject/cli/releases>
-* Download the latest `fn.exe`.
-* Copy the file into the `C:\Windows` directory.
-
-The Fn client is now in your `PATH` and ready to go.
-
-### (2) Windows 10 without Access to System Directories
-If your IT department has locked you out of your system directories, then there are more steps for you to do.
-
-1. Go to: <https://github.com/fnproject/cli/releases>
-2. Download the latest `fn.exe`.
-3. Create a directory for Fn.
-    1. `cd c:\`
-    2. `mkdir fn`
-4. Copy `fn.exe` to that directory.
-5. Add your new directory to the path.
-    1. **Right-click** the **Start menu**.
-    2. Select **System**.
-    3. Scroll down in the main window and **Click** on the link **System Info**.
-    4. In the System dialog box, click **Advanced system settings**.
