NO_USER_MODE_CONTEXT
The result bug check has a value of 0x0000000E.
In the process of starting a system thread, if control returns from the initial thread procedure, a bug check will occur.

Resolution for NO_USER_MODE_CONTEXT
for it, The !analyze debug extension displays information about the bug check and can be helpful in determining the root cause.
Dump evidence
Preserve the complete dump, the four bug-check parameters, the exact Windows build, loaded-module list, and the event timeline immediately before the stop. AllStat summarizes the condition as “this result”; that sentence identifies the failure class, while the parameters and stack determine which object, driver, processor, or subsystem instance was involved.
Analysis order
- Run WinDbg
!analyze -v, then inspect the documented meaning of each parameter instead of relying only on the probably-caused-by line. - Find the earliest abnormal event: driver update, firmware change, device reset, storage error, verifier report, resource exhaustion, or application hang connected with user / mode / context.
- keep third-party filter, security, storage, graphics, and virtualization drivers in the module inventory; removing evidence before dump analysis can obscure the responsible path.
Do not repeatedly reboot a machine affected by this result before collecting the dump and event logs. Recovery actions should follow the component identified by the stack and parameters, not merely the symbolic stop-code name.
Distinctive failure boundary
This result identifies missing expected user-mode execution context. Inspect the trap frame, previous processor mode, thread state, system-call or exception transition, and the code that attempted to consume user-mode context.
Separating the result from neighboring bug checks
Do not infer that a user application is faulty until the dump shows which kernel component expected a user frame and why none was valid. Preserve the original dump and use the documented parameters and stack to verify this distinction before changing drivers or platform configuration.
