Upgrade Dell XPS 15 L502X to Windows 10

Yesterday I upgraded my Dell XPS 15 L502X from Windows 7 to Windows 10. The whole process was smooth except a few problems.
Before upgrade, I uninstalled some software I rarely or seldom used.
  • The Dell Stage should be uninstalled; it is not compatible with Windows 10.
  • OneDrive should be uninstalled too.
  • Firewall software should be uninstalled unless it is compatible with Windows 10.
After upgrade, there were a few issues:
  • No sound: download the latest driver from Dell and reinstall.
  • No HDMI audio:download the latest driver from NVIDIA  and install.
  • OneDrive not working: probably you have OneDrive installed before upgrade and haven’t uninstalled it before upgrade. In Windows 10, search OneDrive, uninstall the OneDrive (Desktop app), and unlink the account via OneDrive tray icon.
  • Could not access Internet: the Windows firewall is set to block everything. Change to the default value “Allow” or disable it for now.


  1. I have also upgraded to windows 10 and for me webcam is not working...It is showing a error message "0*200F4246(0*80040154)". May I know if it is working for you and if it is tell me the solution?

    Thank you for your time.

    1. My webcam is working after upgrade. Try to reinstall Dell webcam software, and update it, it should solve your problem.

    2. Thank you for the reply. I have tried and it is not working.

    3. You can go to Device Manager, expand the Imaging devices, and see if there is an Integrated Webcam or any question mark. You may try the following:
      1 make sure your computer does not have malware or virus. This is very important.
      2 uninstall Integrated Webcam by right clicking it, and restart the computer. You may need to reinstall Dell Webcam central again.
      3 try to update driver.
      4 if all not work, you may go to to seek for help.

    4. When you upgraded, was it via the ISO file, or the built in update tool Microsoft installed on all our PCs?

      I'd like to do the update, but I've yet to receive the notification that the update is ready for my xps. I'm debating if I should wait or just use the ISO and go ahead anyway

    5. I installed mine through Windows update. But I also helped others install with the Windows media creation tool for Windows 10:
      1 download the ISO,
      2 using WinRAR to unzip to a folder C:\Win10, then start from there.

      Both worked well.

  2. Anybody successfully install windows 10 in xps 15 l502x... if yes please provide instructions... specially for drivers... thanks in advance...
