RE: Can I cancel a downgrade from Windows 10 to windows 8?
What happens if you reboot the PC?
If you really want to revert to 8.1, you can download the free Microsoft tool to create your own reinstallation disk here. You can do this on any PC.
If you want to restore Win 10, you can get that tool for free here, if the existing version on the HDD is corrupted and can't be refreshed or restored using the built-in Win 10 tools.
Keep in mind that everything on the drive will be lost, so your files have to be backed up on external media before you do anything else.
