Symptoms


When you try to write some data onto a CD or DVD on a computer that is running Windows Server 2008 R2 or Windows 7, the computer may stop responding. Additionally, you receive the following Stop error message:

STOP: 0x0000007E (parameter1, parameter2, parameter3, parameter4)
Note This Stop error describes a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED issue.
Notes
  • The parameters in this Stop error message vary, depending on the configuration of the computer.
  • Not all "STOP: 0x0000007E" errors are caused by this issue.

Cause


This issue occurs because of an error in the Udfs.sys driver. Under certain conditions, the Udfs.sys driver tries to access a variable without checking whether its value is NULL. If its value is NULL, the issue described in the "Symptoms" section occurs.
