    Driver bug check


    This issue is caused by a driver bug check during second boot while installing Windows 8.1. I request you to check if all the updates are installed on the computer via Windows Update before you start with the Windows 8.1 installation. It would be great if you can provide more information regarding this issue:

    1) What is the make and model of the computer?

    2) Do you have any external devices (except the mouse and the keyboard) connected to the computer?

    3) Are you using any third party security program installed on the computer?

    You may try the following methods and check if that helps.

    Method 1: Disconnect all the unnecessary external devices connected to the computer (except the mouse and the keyboard)

    Please disconnect all the unnecessary external devices connected to the computer (except the mouse and the keyboard) and then check if you still face this issue while installing Windows 8.1. This is to check if the issue is caused by any external devices connected to the computer.

    You may also try installing all the driver updates for all the devices installed on the computer and check if that resolves the issue. You may try the next methods and let’s know the result.

    Method 2: Update the Device Drivers on the Computer.

    Step 1: Check the Windows updates for any latest driver updates.

    Check in Windows updates if any driver updates are available. If so, install the same and check if it helps.

    a) Press “Windows Logo” + “W” keys from the keyboard.

    b) Type “Updates” in the search bar and click on “Install optional updates” from the left pane.

    c) From the “Windows Update” window, click on “Check for Updates” on the top left corner, to receive a fresh list of updates and then install all the updates listed there.

    For any issues while installing Windows Updates, you may also refer to this link:

    Troubleshoot problems with installing updates

    If no driver updates are available via Windows Update, then you may install them for all the devices on the computer from the Computer Manufacturer’s website.

    Step 2: Update Driver Software from the Manufacturer’s website:

    Go to the computer manufacturer’s website and search for the latest Windows 8 drivers available for all the devices on the computer and then install them by following the instructions given in the website

  • Just to add one more problem: the Windows 8.1 Pro downloader & installer from Windows Store is not resumable.

    Fix this Microsoft.

    The downloader & installer from Windows Store must be resumable.

    In fact, ANY downloader & installer must be resumable.
