## FAQ

  * ### How do I use it?

    Very simple! These are the steps:
    
    - Start the container and get some coffee, it will begin downloading the ISO file.

    - Connect to port 8006 of the container in your web browser and wait until you see the screen.

    - 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 specify another Windows version?

    You can add the `VERSION` environment variable to your compose file, in order to specify the Windows version you want to download:

    ```yaml
    environment:
      VERSION: "win11x64"
    ```
    
    Select from the values below:
    
    - ```win11x64``` (Windows 11)
    - ```win10x64``` (Windows 10)
    - ```win81x64``` (Windows 8.1)
    - ```win2022-eval``` (Windows Server 2022)
    - ```win2019-eval``` (Windows Server 2019)
    - ```win2016-eval``` (Windows Server 2016)

  * ### How do I install a custom ISO file?

    You can supply your own ISO file by naming it ```custom.iso``` and placing it in the ```/storage``` folder.

    Make sure to delete every other file in this folder, so that there are no leftovers from previous installations. Then follow the same steps as for [manual installation](https://github.com/dockur/windows/tree/master?tab=readme-ov-file#how-do-i-perform-a-manual-installation).

  * ### 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 data 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: "128G"
    ```
    
    This can also be used to resize the existing disk to a larger capacity without any data loss.
    
  * ### How do I change the location of the data disk?

    To change the location of the data disk, 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 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.

  * ### How do I view the screen?

    The container includes a web-based viewer, so you can visit [http://localhost:8006/](http://localhost:8006/) using any web browser to view the screen and interact with Windows via the keyboard or mouse.

    This is mainly for use during installation, as afterwards you can use Remote Desktop, TeamViewer or any other software you prefer.

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

    If you prefer to perform the installation manually in order to customize some options, add the following environment variable:

    ```yaml
    environment:
      ATTENDED: "Y"
    ```

    Then follow these steps:

    - Start the container and wait until the ISO download is finished. If needed, you can view the progress in the Docker log.

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