## FAQ

  * ### How do I use it?

    Very simple! These are the steps:
    
    - Start the container and get some coffee.

    - Connect to port 8006 of the container in your web browser.

    - Sit back and relax while the magic happens, the whole installation will be performed fully automatic.

    - Once you see the desktop, your Windows installation is ready for use. Enjoy it, and don't forget to star this repo!

  * ### How do I select the Windows version?

    By default, Windows 11 will be installed. But you can add the `VERSION` environment variable to your compose file, in order to specify an alternative Windows version to download:

    ```yaml
    environment:
      VERSION: "win11"
    ```
    
    Select from the values below:
    
    - ```win11``` (Windows 11)
    - ```win10``` (Windows 10)
    - ```win81``` (Windows 8.1)
    - ```win22``` (Windows Server 2022)
    - ```win19``` (Windows Server 2019)
    - ```win16``` (Windows Server 2016)

  * ### How do I increase the amount of CPU or RAM?

    By default, 2 CPU cores and 4 GB of RAM are allocated to the container, as those are the minimum requirements of Windows 11.

    To increase this, add the following environment variables:

    ```yaml
    environment:
      RAM_SIZE: "8G"
      CPU_CORES: "4"
    ```

  * ### How do I change the size of the disk?

    To expand the default size of 64 GB, add the `DISK_SIZE` setting to your compose file and set it to your preferred capacity:

    ```yaml
    environment:
      DISK_SIZE: "256G"
    ```
    
    This can also be used to resize the existing disk to a larger capacity without any data loss.
    
  * ### How do I change the storage location?

    To change the storage location, include the following bind mount in your compose file:

    ```yaml
    volumes:
      - /var/win:/storage
    ```

    Replace the example path `/var/win` with the desired storage folder.

  * ### How do I perform a manual installation?

    If you prefer to perform the installation manually in order to customize some options, such as selecting another edition, add the following environment variable:

    ```yaml
    environment:
      MANUAL: "Y"
    ```

    Then follow these steps:

    - Start the container and connect to port 8006 of the container in your web browser. After the download is finished, you will see the Windows installation screen.

    - Start the installation by clicking ```Install now```. On the next screen, press 'OK' when prompted to ```Load driver``` and select the ```VirtIO SCSI``` driver from the list that matches your Windows version. So for Windows 11, select ```D:\amd64\w11\vioscsi.inf``` and click 'Next'.

    - Accept the license agreement and select your preferred Windows edition, like Home or Pro.

    - Choose ```Custom: Install Windows only (advanced)```, and click ```Load driver``` on the next screen. Select 'Browse' and navigate  to the ```D:\NetKVM\w11\amd64``` folder, and click 'OK'. Select the ```VirtIO Ethernet Adapter``` from the list and click 'Next'.

    - Select 'Drive 0' and click 'Next'.

    - Wait until Windows finishes copying files and completes the installation.

    - Once you see the desktop, open File Explorer and navigate to the CD-ROM drive (E:). Double-click on ```virtio-win-gt-x64.msi``` and proceed to install the VirtIO drivers.

    - Now your Windows installation is ready for use. Enjoy it, and don't forget to star this repo!

  * ### How do I install an unsupported version?

    You can specify an URL in the `VERSION` environment variable, in order to download a custom ISO file:
    
    ```yaml
    environment:
      VERSION: "https://example.com/win.iso"
    ```
    
    During the installation you will need to add some drivers as described in [manual installation](https://github.com/dockur/windows/tree/master?tab=readme-ov-file#how-do-i-perform-a-manual-installation) above.

  * ### How do I pass-through a disk?

    It is possible to pass-through disk devices directly by adding them to your compose file in this way:

    ```yaml
    environment:
      DEVICE: "/dev/sda"
      DEVICE2: "/dev/sdb"
    devices:
      - /dev/sda
      - /dev/sdb
    ```

    Use ```DEVICE``` if you want it to become your main drive, and use ```DEVICE2``` and higher to add them as secondary drives.
    
  * ### How do I verify if my system supports KVM?

    To verify if your system supports KVM, run the following commands:

    ```bash
    sudo apt install cpu-checker
    sudo kvm-ok
    ```

    If you receive an error from `kvm-ok` indicating that KVM acceleration can't be used, check the virtualization settings in the BIOS.

    Yes, this project contains only open-source code and does not distribute any copyrighted material. Neither does it try to circumvent any copyright protection measures. So under all applicable laws, this project would be considered legal.
