How to fix Wificx.sys BSOD in Windows?

Issue: Hello, I'm having repeated Blue Screen of Death crashes with Wificx.sys referenced as a reason for it. BSODs appear regularly, sometimes several times an hour, to the point when it became really frustrating to use my computer. Any advice on how to fix this would be appreciated.

Solved Answer

The Blue Screen of Death[1] error is commonplace among Windows users, and it usually appears randomly. When it does occur, the computer will shut down and restart automatically without any prior warning, often interrupting whatever work or other activities the user was in the midst of. To put it mildly, BSOD can go from being a minor annoyance to an absolute disaster.

Despite how many users could be completely annoyed by these inconveniences of random restarts, they serve an important function within any Windows environment – they prevent further damage that would otherwise be catastrophic. In other words, BSOD occurs when it encounters an error it can't recover quickly, so a system restart is forced.

While for most users, Blue Screen crashes remain the inconveniences of a moment, others suffer from persistent issues, and these matters should be taken seriously. Wificx.sys BSOD was reported by many users, as they started receiving random shutdowns on a regular basis – so much so that it disrupts their computing time greatly.

To get to the root of the problem and resolve it, one should first check what the Wificx.sys component relates to. Initially, it is an architecture provided by Microsoft to program network drivers, so if something within it fails, users may experience a Blue Screen crash. Repeated instances indicate that the issue is persistent and needs to be addressed ASAP.

3. Reinstall network drivers

If updating drivers didn't do the trick, you could try to clean installing them. Thus, you should uninstall the existing driver:

Important: It is very important to download the driver before you uninstall it, as your internet connection will be gone. If you have access to another computer or a phone connected to the internet, it should not be a problem, as you can transfer the driver via a USB stick or other storage devices.

  • Right-click on Start and pick Device Manager
  • Expand the Network Adapters section
  • Right-click your network adapter (for example, Realtek PCIe) and select Uninstall device
  • In the new window, tick the Delete the driver software for this device option and click Uninstall

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
