This article describes an issue that occurs after you install service packs or hotfixes in Windows RT 8.1, Windows 8.1, or Windows Server 2012 R2. A hotfix is available to resolve this issue. Before you install this hotfix, see the Prerequisites section.
System crashes on restart, and you receive a Stop error message that resembles the following:
STOP: 0x0000007E ( parameter1, parameter2, parameter3, parameter4 )
- This Stop error indicates a SYSTEM_THREAD_EXCEPTION_NOT_HANDLED issue.
- The parameters in this Stop error message vary, depending on the configuration of the computer.
- Not all "0x0000007E" Stop errors are caused by this issue.
This issue occurs because the driver directory is compressed after you install service packs or hotfixes. During system restart, the Windows software trace processor (WPP) causes uninitialized memory to be accessed, and then the system crashes.
