    Source here: https://github.com/billyhulbert/XvddKeyslotUtil

    Dump the CIK (Content Integrity Key) for registered MSIXVC packages that are from the Xbox app on Windows 10. By utilising Kernel-Bridge, this utility directly reads the keyslot table belonging to XVDD, the Xbox Virtual Disk Driver, and store the key data into a file format - for usage with xvdtool.

    Usage (REQUIRES ADMINISTRATOR!)
    usage: xvddkeyslotutil [options] ...
    options:
    -h, --help print usage
    -o, --output output path for *.cik files
    -d, --kb kernel-bridge driver path (to kernel-bridge.sys)

    example:
    xvddkeyslotutil --output "E:\CIK" --kb "E:\Kernel-Bridge\Kernel-Bridge.sys"

    Decryption & Extraction
    Use xvdtool by emoose.

    example:
    # Decrypt
    xvdtool -nd -eu -cik "33EC8436-5A0E-4F0D-B1CE-3F29C3955039" -cikfile "E:\CIK\33EC8436-5A0E-4F0D-B1CE-3F29C3955039.cik" "E:\Game\DemoGame.msixvc"
    # Extract
    xvdtool -nd -xf "E:\Game\DemoGameExt" ""E:\Game\DemoGame.msixvc"
