    Windows 10

    The windows icon on screen seems dead.

    I have restarted the PC, I have signed in and out.
    The windows icon on the taskbar suddenly has gone dead. It reacts when I hover but nothing happens when clicking normal.
    Clicking "other button" shows a menu
    Other buttons on the taskbar works. Ihave checked for updates and it says its up to date.
    I have a laptop with W10, no problem and also another desktop no problem

    Hello, there are so many threads on this forum about start menu problems- at least, I assume you mean you can't launch the start menu from the start button (usually bottom left). If you search the forum, you may well find an appropriate solution.

    However, I did come across something new yesterday:
    If your start menu fails to appear, try this:


    But do not try option 4 - powershell command- as this has been broken and will break apps since last November.

    Finally you have the option to do an In-place upgrade install repair.

    For this you need an installation medium with the same build as you have installed.
    Repair Install Windows 10 with an In-place Upgrade - Windows 10 Forums
    This will refresh Windows, after the manner of a Windows installation.
    - all/most associations will be unchanged
    - all your programs will be left installed
    - you will lose any custom fonts
    - you will lose any customised system icons
    - you may need to re-establish your Wi-Fi connection
    - you will need to redo Windows updates subsequent to the build you have used for the repair install
    - system restore will be turned off- you should turn it on again and I recommend you manually schedule a daily restore point.

    This is one of the better features of Win10: as each major build comes out, that's your updated reference build, and as updates are mostly cumulative, there will be few to do.

    Before you perform this major repair procedure, do create a disk image.

    Please consider using disk imaging regularly. It's a brilliant way to
    - preserve your system (and your sanity)
    - back up your data
    - restore your system to a previously working state in a relatively short time

    Recommended: Macrium Reflect or Aomei Backupper (free) + their boot disk/device + large enough external storage medium.

    Good luck!

    Strange things happening. I noticed that the WMI Provider Host was running at 7.5% cpu, no interent activity and a good chunk of memory and has been doing for some time.
    I disconnected my internet but it continued running.
    I restarted the computer with the internet cable unplugged.
    The start button suddenly works. WMI now running at 1.7% cpu
    I connect the internet cable and check for internet. Its OK
    I will now restart this computer with the internet cable connected and come back with result

    Computer restarted and works ok.
    What did I do?
    It seems that closing down of internet and restart the computer without internet stopped some activity the WMI Provider Host was doing. (and seemed to loop around doing)
    A restart after that with internet connected my start button worked again
