Blue screen on Windows 10 caused by Displaylink driver

This has been an issue since we have upgrade to Windows 10. The systems got blue screen all the times with the error PAGE_FAULT_IN_NONPAGED_AREA in dlkmd.sys. Do not bother to download any drivers from Displaylink website. The only fix works for us is to apply Windows 10 Anniversary update 2016 (8/2/2016) which has integrated Displaylink driver into OS.

Windows 7 SP1 Windows Update stuck at "checking for updates"

On my fresh built Windows 7 SP1 64bit PC without any applications installed, the Windows Updates stuck at "Checking for updates" and made no progress. I also saw "Error 0x8024d00e: window update core" on ReportingEvents file in C:\Windows\SoftwareDistribution directory. There are a lot of solutions on Google and I had tried several ways without any luck. Eventually I found out the solution working for my situation and the tool solved my issue is Windows Update Troubleshooter.

Download the Windows Update Troubleshooter first from here,

The steps I took to fix all my issues:

  1. Make sure IE11 is installed on fresh built OS.
  2. As most of people have suggested, download and install the latest "Windows Update Agent" as the first step.

    In my case, I could not even install it because it stuck at "Searching for updates on this computer..." So I tried to downloaded this fix, to resolve, but it stuck at "Searching for update..." again.
  3. Here comes the rescurer: Run Windows Update Troubleshooter then install KB3102810
  4. Run Windows Update Troubleshooter AGAIN then install KB3135445
  5. Run Windows Update Troubleshooter ONE last time, then launch Windows Updates from the Control Panel, shortly all the updates will be available, then process to install.
Hope this helps you too!!
