I accidentaly uninstalled my NVIDIA graphics driver - now Windows 10 can't detect my NVIDIA GT-745M

Yesterday, I decided to upgrade my NVIDIA graphics driver to the latest version because the one included in my Windows 10 90-day trial is quite outdated.

So I made an unforgivable mistake - I uninstalled the driver natively installed in Win 10 because I was sure it would be impossible to install a new driver over the old one - the result is the following: The OS (meaning neither the Device Manager nor the installer of the latest driver) has become unable to detect my graphics card. Intel-integrated graphics works yet, though.

But since I'm a heavy and notorious gamer, Full HD  movie fan and also rely on my GPU to do performance demanding tasks - the on-board graphics in my Lenovo laptop are simply too weak for my purposes. Can anyone help me fixing this issue?

Additional information on my setup:

-Windows 10 Enterprise Evaluation

-Version: 1709

-OS Build: 16299.192

-64-bit processor/64-bit Win 10

-16 GB DDR3 RAM

-Intel Core i7-4700MQ (2.39 GHz)

-No pen or touchscreen input devices installed

-Device ID: 32E7CB62-45C6-4A29-A8BD-901DC64A520C

-Basic telemetry settings

-Location services disabled

-IPv6 access not available(because of my ISP), therefore only IPv4 networking

Notice: My display name is "linuxandwindowsuser" because I also use Fedora (64-bit) on an almost equal Lenovo laptop next to the Win 10 one.

    Go to:

    http://www.nvidia.in/Download/index.aspx?lang=e...

    Select Automatically download and Scan the driver utility.

    If that is a desktop, you can try plugging in and out the card.

    My sincere recommendation, if ain't broke, don't try fixing it. Windows Update and drivers are notoriously buggy these days and having the latest is not necessarily the best. I encourage you to create a system restore point in case something happens.

    Intel is advising users not install any of the available patches for the Spectre/Meltdown issue at this time. They are bricking machines.

    Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.

    Thanks your solution works - now I can use my NVIDIA graphics card again. But I have two more questions:

    Is it possible to install a new graphics driver over an old one? Or will this soft-brick my machine, requiring me to do some sophisticated command line stuff or even re-install the entire OS ?

    And where can I get the latest, official Intel microcode for my Win 10-based Intel-64 machine?

    I'm Greg, an installation specialist and 8 year Windows MVP, here to help you.

    If Nvidia isn't showing up in Device Manager reached by right clicking the Start Menu, from the Action tab choose Scan for Hardware.

    If that isn't enough run the Hardware Troubleshooter from Settings > Update & Security > Troubleshoot.

    Next try installing the Nvidia software. If you have switchable graphics you need the full Nvidia software package, which should come from the PC's Downloads page since it might be customized.

    I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

    Press Windows key + X

    Click Device Manager

    Expand Display adapters

    Right click the current display adapter

    Click Properties

    Click Driver tab

    Click Rollback driver if the option is available

    If not

    Right click the current display adapter

    Click Uninstall

    Exit Device Manager

    Restart

    If you can download the old driver, do so and proceed to install it or try to install an available driver through Windows Update.

    Go to Start -> Settings -> Update & security, then Check for updates and install any available updates.
