  1. After installing KB4562900 updates select keys not functioning


    After running windows 10 1903 update KB4562900 Cumulative Update Preview for .NET Framework on 30th July few of the keys have stopped working. The keys 0, 9, o, l, ., up down right left keys are not functioning. Uninstalled the quality update and even tried to uninstall from Advance Options but after uninstalling the update, again it had installed two other updates KB4560960 and KB4565633. The windows application log show the event 'The program explorer.exe version 10.0.18362.959 stopped interacting with Windows and was closed. Log Name: Application Source: Application Hang Date: 30-07-2020 19:37:11 Event ID: 1002' exact during the time the key blocking issue start to show up.

    When tried to update the Standard PS/2 keyboard driver from the Device Manager it show 'The best driver for the device are already installed' message. Even after all this the keys are still not functioning.

  2. KB4565483 and KB4562900 repeatedly fails to install

    I am currently operating on Windows 10 Pro. It was functioning smoothly without any issues and used to update every time easily. But when
    Cumulative update for Win10 ver 1909 (x64) (KB4565483) rolled out, my PC failed to update to it. When other updates came after this one, they got installed easily but this one failed everytime. Till date it has failed to install 8 times (Even
    after redownload).

    Yesterday Cumulative Update Preview for .NET Framework 3.5and 4.8 for Win10 ver 1909 (x64) (KB4562900) also failed to install.

    Kindly help
