SL_REMAPPING_SP_PUB_TAMPER_SECURITY_PROCESSOR_PATCHED
What the protected licensing code means
0xC004D402 maps to SL_REMAPPING_SP_PUB_TAMPER_SECURITY_PROCESSOR_PATCHED. This result belongs to Software Protection integrity and kernel-cache enforcement and narrows the operation to the integrity path that authenticates protected modules, compares security-processor state with kernel-mode policy data, restores cached state and detects proxy or patch interference. In concrete terms, the security-processor implementation appears patched or inconsistent with the signed platform image.
the first result diagnostic fork is precise: the result targets the processor implementation itself rather than one license file. That is why this result can require a different correction from the same visible activation banner.
Minimum data for a reliable diagnosis
- kernel-cache policy generation and reboot state
- SFC/DISM results and Security-SPP event correlation
- exact module/file and version
- digital signature and file hash
- OS build and servicing level
From HRESULT to a verified cause
- Identify the caller and operation instance that produced
0xC004D402. - Collect the code-specific evidence: capture loaded module paths, code-signing results, hashes, boot state and servicing logs.
Where it sits in the licensing pipeline
A module or cache integrity result should be investigated as a component-integrity problem before changing product keys or activation endpoints. To verify this, capture loaded module paths, code-signing results, hashes, boot state and servicing logs.
Servicing tools can repair protected system files, while unofficial replacements, patchers or permission resets can create a second mismatch and destroy provenance.
Why the symbolic code matters
| Result | Different condition |
|---|---|
SL_REMAPPING_SP_PUB_TAMPER_MODULE_AUTHENTICATION | Compared with this result, a protected module failed authentication against the expected signed system component. |
SL_REMAPPING_SP_PUB_KM_CACHE_TAMPER | Compared with this result, kernel-mode licensing cache data fails its integrity check. |
SL_REMAPPING_SP_PUB_KM_CACHE_TAMPER_RESTORE_FAILED | Compared with it, the platform detected a damaged kernel-mode cache and its automatic restoration attempt also failed. |
Targeted fix
Remove unsupported modifications and repair the Windows image from a trusted matching source.
Representative case: An activation bypass modifies security-processor code in memory or on disk.
Actions that usually destroy useful evidence
- Do not use unofficial activation, patching or proxy tools to bypass the integrity check.
- Do not replace protected binaries from another computer or build.
