How To Fix And Prevent The 0x0000007F Error

0x0000007F Error

The 0x0000007F error is a member of the “blue screen” errors – causing your computer to restart and show a blue screen whenever you try and do certain things. This error is primarily caused by an issue with the “kernel” of Windows and needs to be fixed by using the registry and other parts of your system.

What Is The 0x0000007F Error?

The oxoooooo7F error is caused when your computer has a lack of sufficient kernel space to process kernel-mode drivers. The kernel is the most central component of most computers operating systems, it is actually used as a bridge between applications and data processing done at the hardware level.

Programs such as Symantec AntiVirus Corporate Edition 8.0 install a kernel-mode driver that uses a filter driver that registers with the kernel. When Symentec AntiVirus, or Norton AntiVirus file system real-time protection explores a file for viruses, it requests file access from the file system. These file I/O (Input/Output) requests can add to the kernel space that a users computer takes up.

How To Fix The 0x0000007F Error

Step 1 – Add “KStackMinFree” Entry In Registry

First of all you need to add the “KStackMinFree” value to the registry. The KStackMinFree value specifies the minimum kernel space that must be available for Symentec AntiVirus and even Norton AntiVirus file system real-time protection to request file I/O (Input/Output) from the file system. Here’s how you do it:

For Symantec AntiVirus 9.x or later

  1. In the Registry Editor, go to the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\INTEL\LANDesk\
    VirusProtect6\CurrentVersion\Storages\Filesystem\RealTimeScan
  2. Right-click the RealTimeScan key, and then click NewDWORD Value.
  3. Type KStackMinFree for the name of the new value.
  4. Right-click the KStackMinFree value, and then click Modify.
  5. Set the Base to Hexadecimal, and then type 2200 in the Value field.
  6. Click OK.
  7. Restart the Symantec AntiVirus service.

For Symantec AntiVirus 8.x

  1. In the Registry Editor, go to the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Symantec\
    Norton AntiVirus NT\Auto-Protect\InternalSettings

  2. Right-click the InternalSettings key, and then click NewDWORD value.
  3. Type KStackMinFree for the name of the new value.
  4. Right-click the KStackMinFree value, and then click Modify.
  5. Set the Base to Hexadecimal, and type 2200 in the Value field.
  6. Click OK.
  7. Restart the Symantec AntiVirus service.

Step 2 – Check All Hardware Is Working Correctly

After you’ve added this registry entry, you also need to check the hardware is working fine on your system. Kernel errors are often caused by hardware issues, making it vital that you have perfectly functioning hardware on your system to make your PC work as smoothly as possible.

To do this, you should first  check the rear of your computer and carefully make sure that the hardware that is connected to your computer and all are connected and working fine. This ensures the function of your machine which should work fine. Hardware which is the physical aspects of the computer is a fundamental component of a PC, its not just things like a mouse or keyboard, but its what actually inside the computer that matters, for example the motherboard is the main component which connects other components such as the CPU, the RAM and the disk drives.
