    Help Required !
    I accidentally deleted two drivers (serenum.sys, CH341S64.sys) which I required on my windows 8 64bit pc.
    I needed them for serial communication with my arduino . I connected the same arduino to another PC (My father's) and it was detected . The other PC was a win10 and i checked the drivers it was using for communication with the arduino(they were serenum.sys, CH431S64.sys). I copied them onto my computer but drivers require a .inf file which I lack. So I have the .sys files but cant use them on the win8 pc.

    Thank You for reading.

    Have you tried restoring your computer to an earlier date.

    If that's a factory-brand and not a self-built computer, advise us what its brand name and model name and complete model number is.

    Go into the Device Manager.
    Are there any entries that are listed as other devices or unknown devices?

    Personal files and document are not affect on the system restore point (not sure about the 'return to factory settings' option). Software updates and such are what is lost.

    To be safe you should have your data backed up to at least one external source (hard drive or cloud). This is a must for every one regardless of the need for a system restore.

    You have THIS HP Pavilion 15-e009tu Notebook PC which came with Windows 8 64-bit.

    Is it running Windows 8 64-bit or Windows 8.1 64-bit?

    Select "Software And Drivers", then select the appropriate operating system so the list of drivers can appear, then expand each heading to see if the driver you need is listed there.

    Double-click COM22 to open its properties window.
    Select the "Details" tab, then select "Hardware Ids" in the drop-down list.
    Submit an image of that window.

    Yes This is the one .

    I am using windows 8.1 64-bit.

    I don't see my driver listed there.

    Here is the snap. I hope this is the one.

    Go HERE.
    If you're asked to allow an add-on to be installed, do so.

    The second entry down from the top of the list is for Windows 8.1 64-bit.
    Click "Add", then click "View basket", then click "Download".
    Browse to the location in your computer that you want to save the file, then click "Continue".
    After the download process finishes, click "Close".

    Open that saved folder to expose its contents.
    Right-click that .cab file, then extract its contents into that same folder.
    These are the files that'll appear:
    Capture.JPG

    Go back into the Device Manager, then display the properties window for that COM22 entry.
    Click "Update Driver", then select the option to browse to the driver that you've saved in your computer.
    If you do it correctly, it'll eventually display the .INF file and allow you to install the driver.

    Using the Device Manager "back door" method to install a driver can be tricky because there's more than one way to do it.
    I had to install a wireless driver yesterday using the "back door" method.
    The first way I did it failed, but the second way was successful.

    The Windows 8 64-bit driver that I linked you to has the CH341S64.sys file, but not the serenum.sys file, so I don't know if it's going to work for you.

    Updating a driver via the "Update Driver" feature in a device in the Device Manager is what I refer to as "the back door method".
    A driver file usually comes in executable(.exe) form where double-clicking it starts the install process.
    It may also come in compressed(.zip, .cab) form which requires extracting it first and then installing it through the Device Manager.
    This is what I attempted to have you do.
    There's nothing harmful about it.
