Troubleshooting Docker installation on Windows

[pranjal-joshi]

Though, the Docker installation is pretty straightforward and I have already made a **[video tutorial], some Windows users still face Issues while Installing the docker properly or while launching the container from Screeni-py image due to one of the following reasons:

1. Some important features are not already enabled on Windows Home / Student / Enterprise edition which are enabled in Pro edition.
2. Windows sub-system for Linux (WSL) is not Installed or not updated.

Common Issue and How to Fix them?

1. Unexpected WSL error - Mostly Happens for Windows Home/Student Edition

Solution

1. Search "Turn on Windows features" into the Windows search bar.
2. Enable "Windows Subsystem for Linux" and "Windows Hypervisor or Hyper-V" features by ticking the checkboxes.
   
3. Click on 'OK' button
4. Reboot your PC
5. Open command prompt and run wsl --update command
6. Reboot your PC once again
7. Check if Docker is working or Docker pull is working.
8. If the issue still persists, Shutdown your PC and go to the BIOS setup.
9. Enable Virtualization and VT-D settings from BIOS if disabled. (Your BIOS may look totally different than the example as BIOS is customized by every PC manufacturer!)
   

2. WSL version is too low

Solution

1. Open command prompt and run wsl --update command.
2. Reboot your PC.
3. Check if Docker is working properly.
