Have you installed the latest version of the Windows 10 operating system to see how it works? Unfortunately, some users have had problems with the Ndu.sys bug while traveling. This is certainly one of the most common and not so simple errors you can get in Windows 10.

Common Ndu.sys Error Messages

The majority of Ndu.sys errors you encounter are “Blue Screen of Death” errors (also known as “BSOD” or “STOP” errors) that occur in Windows XP, Vista, 7, 8 and 10:

  • “A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: Ndu.sys.”
  • “:( Your PC ran into a problem and needs to restart. We’re just collecting some info, and then we’ll restart for you. If you would like to know more, you can search online later for this error: Ndu.sys.”
  • “STOP 0x0000000A: IRQL_NOT_LESS_EQUAL – Ndu.sys”
  • “STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED – Ndu.sys”
  • “STOP 0×00000050: PAGE_FAULT_IN_NONPAGED_AREA – Ndu.sys”

In most cases, Ndu.sys blue screen errors occur after installing new hardware or software. These Ndu.sys blue screens may appear during program installation, when running Ndu.sys-related software (for example Windows 8 Pro), when loading a Microsoft driver, or when starting or stopping Windows. Tracking when and where your STOP error occurs is important information for troubleshooting the problem.

Rename the Ndu.sys Folder to Fix the BSOD Error

  • Open the “My Computer” icon by double-clicking it or by going to the “Start” menu and left-clicking it.
  • Double-click the icon to enter the C:/ partition or the partition where you installed the Windows 10 Technical Overview.
  • Double-click the Windows folder to open it.
  • Now locate the System32 file in the Windows folder and double-click it to open it.
  • Now go to the System32 folder, locate the drivers folder, and double-click it to open it.
  • After reaching the Drivers folder, you should look for the Ndu.sys file.
  • Right-click the Ndu.sys file and left-click or press the Rename function in the menu that opens.
  • Rename Ndu.sys to Ndu.sys11 or whatever you want, but change the name and remember it.
  • Note: If you can’t change the file name, you will need to log in with your administrator account or simply change the permissions you have for that particular file to “Administrator”.
  • Re-open the C: partition where you installed Windows 10.
  • This time, look in partition C: for the Windows.old folder, because this should be the old Windows operating system you updated.
