SL_REMAPPING_SP_PUB_KM_CACHE_IDENTICAL
What the security processor has established
0x4004D601 maps to SL_REMAPPING_SP_PUB_KM_CACHE_IDENTICAL. 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, a kernel-mode policy-cache refresh produced data identical to the active cache, so no replacement was required.
the first result diagnostic fork is precise: this is an informational no-change result, not cache tampering.
A reproducible troubleshooting path
- Identify the caller and operation instance that produced
0x4004D601. - Collect the code-specific evidence: record policy generation, cache hash and refresh trigger.
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, record policy generation, cache hash and refresh trigger.
Servicing tools can repair protected system files, while unofficial replacements, patchers or permission resets can create a second mismatch and destroy provenance.
Minimum data for a reliable diagnosis
- exact module/file and version
- digital signature and file hash
- OS build and servicing level
- kernel-cache policy generation and reboot state
- SFC/DISM results and Security-SPP event correlation
Recommended handling
Continue normally and avoid forcing unnecessary cache replacement.
Representative case: A scheduled policy refresh recomputes the same kernel cache.
Related codes with different remedies
| Result | Different condition |
|---|---|
SL_REMAPPING_SP_PUB_KM_CACHE_POLICY_CHANGED | Compared with this result, policy changes that require reboot were detected while preparing the kernel-mode licensing cache. |
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_TAMPER_SECURITY_PROCESSOR_PATCHED | Compared with it, the security-processor implementation appears patched or inconsistent with the signed platform image. |
Actions that usually destroy useful evidence
- Do not replace protected binaries from another computer or build.
- Do not use unofficial activation, patching or proxy tools to bypass the integrity check.
