     * If your Windows partition does not have a drive letter, type `sel vol N` where `N` is the volume number shown in Diskpart, then type `assign letter=W`. Your Windows partition will be assigned the drive letter `W:`.
     * Finally, at the `DISKPART>` prompt, type `exit` to exit Diskpart.
 5. Obtain XenBootFix.
-  * If you're using XCP-ng Windows PV Tools 9.1 or later, it is located at `W:\Program Files\XCP-ng\Windows PV Drivers\XenBootFix\XenBootFix.exe` where `W:` is your Windows drive letter.
-  * If you have PowerShell, run the following command: `Invoke-WebRequest https://<download path of XenBootFix.exe> -OutFile XenBootFix.exe`
-  * Failing all that, you can create a new ISO image containing XenBootFix using WinCDEmu, ImgBurn or a similar tool, then attach it to your VM.
+  * The easiest way is to download and use the [latest release ISO](https://github.com/xcp-ng/win-pv-drivers/releases) of XCP-ng Windows PV Tools, which includes a copy of XenBootFix at `package\XenBootFix\XenBootFix.exe`.
+  * If you're using XCP-ng Windows PV Tools 9.0 or later, it is also located at `W:\Program Files\XCP-ng\Windows PV Drivers\XenBootFix\XenBootFix.exe` where `W:` is your Windows drive letter.
   * **Note**: If using Windows PE, do not remove its CD image when it's running. You may encounter unexpected errors otherwise.
 6. Run the command `<path to XenBootFix.exe> W:\Windows` where `W:` is your Windows drive letter.
   * **Note**: Make sure the drive letter belongs to your actual Windows installation and not Windows PE/RE. By default, Windows PE/RE use the drive letter **X:**.
