    "This PC" shortcut opens very slowly ONLY from taskbar


    Hi, I have just finished a fresh installation of Windows 10 Pro in a notebook, and I'm facing a very weird issue. I'm doing this all day, and it's the first time and the only notebook I know that is having this problem. Just in case it's relevant, it's an MSI GL62M 7RDX: i5 7300HQ (Intel HD 630), nVIDIA GTX 1050, 1TB HDD, 8GB RAM...

    All latest Windows updates installed, latest drivers for everything (including both Intel and nVIDIA), etc... it works just fine except for one thing: a shortcut of "This PC" opens incredibly slow if it's opened from the taskbar (pinned).

    So, if I create a "This PC" shortcut in the desktop and open it from there, it opens instantly. If I pin it to Windows 10 "Start" menu, it opens instantly, if I open it from "Classic Shell" start menu, it opens instantly. BUT, if I attach/pin it to the task bar, it takes like 5 seconds to open.

    I don't know how to troubleshoot this. I think it's the File Explorer itslef, when opened from taskbar it is very slow to open.

    I have plenty of PC/desktop/notebook right now and none of them do this. I guess it has something to do with the graphics drivers, but that's just a thought.

    Wait is this for real?

    In my main notebook, which has a Samsung 850 EVO SSD, also happens.

    Did Microsoft F up File Explorer with a recent update?

    No it can't be because I've just checked this issue in a desktop PC and does not happen. So... this is starting to get closer to my initial thought: the graphics drivers, and I guess it's nVIDIA for notebooks. Since this happens in my two notebooks, and they only share the nVIDIA graphics driver and Windows 10 of course. But wait, my desktop has a GTX 1070, it should happen there as well...

    It's an issue with Optimus laptops with Pascal GPUs, and it's been unfixed since the release of Windows 10, i.e. for 3 years now. It (along with a plethora of other bugs, like random GPU spikes and animation stutters) is due to a conflict between the Nvidia GPU, the Intel CPU and Windows 10 itself; and neither Microsoft, nor Intel, nor Nvidia have shown any competence in fixing any of this. They just point fingers at each other. I honestly think going full-AMD is the better choice now when it comes to laptops.

    The issue is fixed ("fixed") by uninstalling the Nvidia display driver.. whooptidoo, you can't use the dedicated GPU.

    No, wait. My main notebook has Widows 10, i7 4700MQ (Intel HD 4600) and nVIDIA GT 755M (Kepler), and this issue was not there until a week or so ago. In other words, THIS PC shortcut has been working fine in my main notebook until now.

    I guess it's some GeForce Experience/nVIDIA newests drivers issue. Nonetheless, my desktop PC has a GTX 1070 (and no Intel GPU) and it does not happen. The fact that it's happening only inn my notebooks could also mean it could be Optimus...

    I have the same problem. Any taskbar related opening of file explorer makes it use the NVIDIA GPU instead of Intel Integrated graphics and causes a delay, unless I make a freshly pinned taskbar shortcut of explorer.exe which is also affected after one logoff/reboot. Pinning explorer.exe from the syswow64 folder can be a temporary solution or binding Windows+E to a mouse button if you have a keyboard with only one Windows key that is out of reach.

    Correct GPU and fast:
    Windows-button+E
    Command prompt: 'explorer .'
    Windows search
    Cortana voice command: 'open file explorer'
    Start menu programs list, folder Windows System, file explorer.

    Incorrect GPU and slow:
    Taskbar
    Right-click menu of Windows icon of taskbar.

    Wow, you're absolutely right, I've tried all those things and it happens what you said. How do you know it's the GPU?

    I guessed it was a GPU related problem, but I don't actually have any proof of that.

    Another question:
    How is it possible that your notebook has a GTX 950M but a 4th generation CPU?
    Shouldn't you have a 6th or 7th generation CPU?

    It's a weird configuration, a recently/new GPU but a 4-5 years old CPU... doesn't make sense (talking about notebooks, not desktops where that would be totally normal).

    Because my power button lights up blue for Intel and orange for NVIDIA.

    Notebookcheck.net says they are both 1100-1200 days old.
    I bought my laptop in October 2015.

    Oh, that's one thing I really love about MSI, that's so cool that depending on what GPU you run things, the LED will change its color.

    OK, that's weird, I've just discovered that your processor, although it's a 4th gen i7, it was released in 2015.

    The i7 4th gen was officially released in 2013, I have an i7 4700MQ, which is almost identical to yours, but mine came in 2013, when I bought my notebook, that's why I have an nVIDIA GT 755M. In 2015, there was the 6th gen i7, and your notebook should have carried an i7 6700MQ or something like that. That's what I saw strage, an i7 4th (like mine) with a GT 900 series GPU instead of a GT 700 series.

    That's why I said it's an Optimus issue, not just an Nvidia issue. I also have an Optimus laptop (6700+1060), so I imagine it's a problem with switching between the iGPU and the dGPU which causes hiccups like this.

    However, Intel just pushed a driver update yesterday through the automatic Windows update, and the issue seems to be gone! At least in my case. File Explorer opens instantly again, and all the stutters are gone! I'm so freaking happy considering how long I've had to deal with this.

    So in case you had disabled automatic updates, definitely try the latest Intel one. I think there's a pretty high chance it'll fix your problem too.

    I'll see that later, thanks.
