Parameters

Parameter	Description
1	The address of the system function (system call) or worker routine.
2	The value of the current thread's ApcStateIndex field.
3	The value of current thread's CombinedApcDisable field. This field consists of two separate 16-bit fields: (Thread >SpecialApcDisable < < 16) \| Thread >KernelApcDisable.
4	Call type: 0 - System call 1 - Worker routine

Description

The APC_INDEX_MISMATCH bug check has a value of 0x00000001. The bug check indicates a mismatch in the asynchronous procedure calls (APC) state index.

Important
This article is for programmers. If you're a Microsoft customer and your computer displays a blue screen error code, see Troubleshoot blue screen errors.

Cause

The most common cause of this bug check is when a file system or driver has a mismatched sequence of calls to disable and re-enable APCs. The key data item is the Thread >CombinedApcDisable field. The CombinedApcDisable field consists of two separate 16-bit fields: SpecialApcDisable and KernelApcDisable. A negative value of either field indicates that a driver has disabled special or normal APCs (respectively) without re-enabling them. A positive value indicates that a driver has enabled special or normal APCs too many times.

Resolution

You can resolve this problem by using WinDbg or by using basic troubleshooting techniques.

Debug by using WinDbg

The !analyze debugger extension displays information about the bug check and can help you determine the root cause.

You can use the !apc extension to display the contents of one or more APCs.

You also can set a breakpoint in the code that precedes this stop code and attempt to single-step forward into the faulting code.

For more information about using WinDbg, see Crash dump analysis using the Windows debuggers (WinDbg).

Debug without using WinDbg

If you aren't equipped to use the Windows debugger to work on this problem:

In Event Viewer, check System Log for more error messages that might help you identify the device or driver that's causing this bug check.
If a driver is identified in the bug check message, disable the driver or check with the manufacturer for driver updates.
Confirm that any new hardware that's installed is compatible with the installed version of Windows. For example, you can get information about required hardware at Windows 10 specifications.

For more general troubleshooting information, see Analyze Bug Check Blue Screen Data.

Remarks

This bug check is the result of an internal error in the kernel. This error occurs on exit from a system call. A possible cause for this bug check is a file system or driver that has a mismatched sequence of system calls to enter or leave guarded or critical regions. For example, each call to KeEnterCriticalRegion must have a matching call to KeLeaveCriticalRegion.

If you're developing a driver, you can use Static Driver Verifier, a static analysis tool available in Windows Driver Kit, to detect problems in your code before you ship your driver. Run Static Driver Verifier with the CriticalRegions rule to verify that your source code uses these system calls in correct sequence.

WinSAT.exe	0x1	1011	Windows System Assessment Tool COMMAND LINE USAGE : WINSAT [switches] It's necessary to supply an assessment name. In contrast, switches are optional. Valid assessment names already seen in Vista include: formal run the full set of assessments dwm Run the Desktop Windows Manager assessment - Re-assess the systems graphics capabilities and restart the Desktop Window Manager. cpu Run the CPU assessment. mem Run the system memory assessment. d3d Run the d3d assessment (Note that the d3d assessment no longer runs the workload. For backward compatibility, pre-determined scores and metrics are reported.) disk Run the storage assessment media Run the media assessment mfmedia Run the Media Foundation based assessment features Run just the features assessment - Enumerates the system's features. - It's best used with the -xml switch to save the data. - The 'eef'switch can be used to enumerate extra features such as optical disks, memory modules, and other items. PRE-POPULATION: The new command-line options for pre-populating WinSAT assessment results are : Winsat prepop [-datastore ] [ -graphics \| -cpu \| -mem \| -disk \| -dwm ] This generates WinSAT xml files whose filenames contain "prepop". For example : 0008-09-26 14.48.28.542 Cpu.Assessment (Prepop).WinSAT.xml The filename pattern is : %IdentifierDerivedFromDate% %Component.Assessment(Prepop).WinSAT.xml The datastore directory option specifies an alternative target location for generated xml files. If no location is specified, everything is pre-populated to %WINDIR%\performance\winsat\datastore. To generate a full set of result xml files, use "winsat prepop". It is also possible to pre-populate results for a subsystem, such as CPU, subject to the following dependencies: The CPU assessment has a secondary dependency on the Memory assessment The Memory assessment has a secondary dependency on the CPU assessment The Graphics assessment has a secondary dependency on both CPU and Memory assessments The DWM assessment can run standalone The Disk assessment can run standalone If the assessment for a secondary dependency is not present, WinSAT will run the secondary assessment along with the requested primary assessment. For example, "winsat prepop -cpu" will run both the CPU and the Memory test, if the xml file for the Memory test is not present. OTHER NEW Win7 ASSESSMENT OPTIONS : dwmformal Run Desktop Windows Manager assessment to generate the WinSAT Graphics score cpuformal Run CPU assessment to generate the WinSAT Processor score memformal Run Memory assessment to generate the WinSAT Memory (RAM) score graphicsformal Run Graphics assessment to generate the WinSAT Gaming Graphics score diskformal Run Disk assessment to generate the WinSAT Primary Hard Disk score All formal assessments will save the data (xml files) in %WINDIR%\performance\winsat\datastore. If a system has been prepopulated (using files generated by the "winsat prepop" option), it is not necessary to run formal assessments. SUB-ASSESSMENTS: While investigating results, it may be convenient to look at individual assessments. Options for running Gaming Graphics sub-assessments include: Winsat graphicsformal3d Winsat graphicsformalmedia DX9 Variations: Winsat d3d -dx9 winsat d3d -batch winsat d3d -alpha winsat d3d -tex winsat d3d -alu DWM/DX10 variations: Winsat d3d -dx10 winsat d3d -dx10 -alpha winsat d3d -dx10 -tex winsat d3d -dx10 -alu winsat d3d -dx10 -batch winsat d3d -dx10 -geomf4 winsat d3d -dx10 -geomf27 winsat d3d -dx10 -geomv8 winsat d3d -dx10 -gemov32 winsat d3d -dx10 -cbuffer OPTIONS FOR FORMAL ASSESSMENTS FOR SUBSEQUENT RUNS ON THE SAME MACHINE: The default behavior for "WinSAT formal" when a complete set of winsat formal files is present and a second "winsat formal" run is requested is to 1) Run incrementally if component change implies that an assessment needs to be re-run, e.g. if a video card were updated 2) If no component updates were detected, re-run all assessments. The restart option enables behavior other than the default. The syntax is : Winsat formal -restart [clean\|never] Winsat formal -restart Reruns all assessments. Winsat formal -restart never Attempts to run incrementally. Winsat formal -restart clean Reruns all assessments and provides the same functionality as "forgethistory". Winsat forgethistory Choosing to forgethistory will rate a machine as if for the first time. OTHER COMMAND LINE OPTIONS : -v Enables verbose output -xml Saves the XML output to 'filename' -log Generates a log file associated with the specified command, such as disk The -log switch can be used with any WinSAT command. viewlog -i Dumps the results of a log file . viewevents Used to view relevant winsat events in the event log. (This launches the event log) query Can be used to query the current datastore.
