Quick answer
SET_OF_INVALID_CONTEXT is Windows bug check 0x00000030. It means that a stack pointer recorded in a trap frame had an invalid value. Specifically, Microsoft says this check occurs when a routine attempts to set that pointer to a value lower than the current stack pointer. Windows stops because continuing could leave the kernel using a stack pointer that points to a stack that is no longer valid. Microsoft Learn
The code describes what Windows detected. It does not, on its own, identify the routine or driver responsible. A crash dump is the best starting point for finding that out.
What are the stack pointer and trap frame?
The stack pointer identifies the current position in a thread’s stack, which holds information used while code runs and calls other routines. A trap frame records processor context associated with an interruption or exception. The debugger can use a trap frame to inspect the register context at that point. Microsoft Learn
For this bug check, the key issue is the attempted change to the stack pointer stored in the trap frame. Microsoft describes a comparison between the new and old pointer values: the new value is lower than the current one. If Windows accepted the change, subsequent kernel execution could use an invalid stack location. That is why the system stops instead of proceeding with the context change. Microsoft Learn
A lower numeric address is the condition Microsoft documents here. It should not be turned into a broader rule that every downward movement of a stack pointer is invalid; the check concerns this particular attempted update to a trap frame.
SET_OF_INVALID_CONTEXT parameters
Microsoft defines all four parameters for 0x30. They are useful when examining the bug check in WinDbg or reviewing a crash report. Microsoft Learn
| Parameter | Microsoft’s definition | How to use it |
|---|---|---|
| 1 | The new stack pointer | The value the routine attempted to set in the trap frame. |
| 2 | The old stack pointer | The previous pointer value used for comparison. |
| 3 | The trap frame address | The address to inspect when the relevant trap frame is available in the dump. |
| 4 | 0 |
A fixed value in Microsoft’s parameter table; it is not a documented subtype. |
Example of how to read the fields: If WinDbg reports Arg1, Arg2, Arg3, and Arg4, treat them in that order as the new stack pointer, old stack pointer, trap-frame address, and zero. The precise hexadecimal values depend on the crash. Do not substitute values from an example into a real analysis.
What causes the stop code?
The documented immediate cause is a routine attempting to put a lower stack pointer into the trap frame than the current stack pointer. Microsoft does not name a particular driver, device, application, or hardware fault as the universal underlying cause. Microsoft Learn
Finding the underlying cause requires more evidence. For example, a debugger might show the code path leading to the invalid context change. A recurring driver in several dumps could be a useful lead. Neither a module name on the stack nor a recent hardware change proves responsibility by itself; each needs to be checked against the full crash record.
How to investigate 0x00000030 in WinDbg
1. Open the crash dump and run the initial analysis
Use WinDbg’s verbose analysis command:
!analyze -vThis displays the bug check, its arguments, and available diagnostic information. Record the four argument values and inspect the call stack and any reported modules. Microsoft documents !analyze as a starting point for bug-check investigation. Microsoft Learn
To display the bug check data directly, run:
.bugcheckThis is useful for confirming that the dump contains 0x30 and for copying its parameters accurately. learn.microsoft.com
2. Compare the new and old stack pointers
Compare Parameter 1 with Parameter 2, using the full values shown in the dump. Microsoft’s description says the attempted new pointer is lower than the current pointer. This check confirms that you are interpreting the parameters in the right order; the comparison alone will not tell you which routine made the change. Microsoft Learn
3. Inspect the trap frame, if it is present
Parameter 3 is the trap-frame address. In a dump that contains the necessary memory, an experienced debugger user can inspect it with:
.trap <Parameter-3-address>Replace the placeholder with the actual address from the dump. The .trap command displays trap-frame information and sets the debugger’s register context to that frame. Availability and completeness depend on the captured dump data. Microsoft Learn
After setting the context, inspect the stack:
kvThe k family of commands displays a stack backtrace; kv includes additional frame information where available. Read that output alongside !analyze -v, since an invalid stack pointer can make a stack trace incomplete or difficult to interpret. Microsoft Learn
4. Look for a repeatable pattern
If there are multiple dumps, compare:
- The code path and modules near the invalid context change.
- The values of the first three parameters.
- The activity taking place when each crash occurred.
- Driver, device, firmware, and Windows changes made before the crashes began.
A pattern across several crashes is stronger evidence than a single module name in one dump. Microsoft’s general stop-code guidance also recommends using dump data and system context to investigate the cause. learn.microsoft.com
Practical troubleshooting for PC users
Microsoft’s 0x30 article is written for programmers and does not provide a code-specific repair procedure. If you are seeing this blue screen on a PC, work from the timing and frequency of the crashes: Microsoft Learn
- Record the exact stop code. Note
SET_OF_INVALID_CONTEXTand0x00000030, along with the date and what you were doing. - Review recent changes. If crashes started after a new driver, device, or update, investigate that change first. Avoid changing several things at once, so you can tell what affects the problem.
- Check for relevant Windows and device updates. Microsoft includes updates among its general blue-screen troubleshooting steps. Microsoft Support
- Keep the crash dump if the problem repeats. It gives a support engineer more to work with than the stop-code name alone.
- Use Windows recovery options if you cannot start Windows. The appropriate recovery step depends on what changed before the startup problem began. Microsoft Support
Do not assume that replacing RAM, reinstalling Windows, or changing a particular driver is the standard fix for 0x30. Microsoft’s code-specific documentation does not support any one of those conclusions without further evidence.
Frequently asked questions
Does SET_OF_INVALID_CONTEXT mean my RAM has failed?
No such conclusion appears in Microsoft’s 0x30 documentation. The documented problem is an invalid stack pointer in a trap frame. Hardware investigation may become appropriate if other evidence points to it, but the stop code alone does not identify failed RAM. Microsoft Learn
What is the difference between Parameter 1 and Parameter 2?
Parameter 1 is the attempted new stack pointer. Parameter 2 is the old stack pointer. Microsoft says the stop occurs when the attempted value is lower than the current value. Microsoft Learn
Is Parameter 3 the faulty driver?
No. Microsoft defines Parameter 3 as the trap frame address. It is an address for debugging the saved context, not a driver name or a direct identification of the component at fault. Microsoft Learn
Does Parameter 4 identify a type of 0x30 failure?
Microsoft lists Parameter 4 as 0 and does not document any subtype values for it. Microsoft Learn
Can I fix this with a command?
There is no Microsoft-documented repair command specific to 0x30. Commands such as !analyze -v and .trap help investigate a dump; the corrective action depends on what the investigation finds. Microsoft Learn
Summary
SET_OF_INVALID_CONTEXT (0x00000030) occurs when Windows detects an attempted invalid update to a trap frame’s stack pointer. The stop-code parameters give the new pointer, old pointer, trap-frame address, and zero, respectively. Use those values with a crash dump and WinDbg to trace the relevant code path, then address the cause supported by the evidence. Microsoft Learn
