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. That is why this result can require a different correction from the same visible activation banner.
A reproducible troubleshooting path
- Identify the caller and operation generation that produced
0x4004D601. - preserve the first inner I/O, crypto, parser or policy status that precedes the public HRESULT.
- collect the code-specific evidence: record policy generation, cache hash and refresh trigger.
- rule out stale handles, parallel activation, incomplete servicing and image rollback where they affect this subsystem.
- retest once, then confirm LicenseStatus/LicenseStatusReason or the equivalent protected-object state persists.
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. The decisive proof for it is to 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. Keep that product/object identity because the same service can expose several independent licensing instances.
Minimum data for a reliable diagnosis
| Item | Why it matters here |
|---|---|
| exact module/file and version | Identifies the protected object or product instance that returned the code. |
| digital signature and file hash | Separates format/version failure from damage, absence or access failure. |
| OS build and servicing level | Shows the state transition immediately before the HRESULT. |
| kernel-cache policy generation and reboot state | Correlates service-level evidence with storage, crypto or policy evidence. |
| SFC/DISM results and Security-SPP event correlation | Reveals whether servicing, migration, restore, cloning or concurrent work changed the precondition. |
Code-specific check: record policy generation, cache hash and refresh trigger.
Recommended handling
Continue normally and avoid forcing unnecessary cache replacement. Preserve the original store, event export, hashes and licensing inventory until the operation succeeds and the expected state survives any required restart.
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 replacing protected binaries from another computer or build.
- do not using unofficial activation, patching or proxy tools to bypass the integrity check.
- While resolving it, do not use unofficial activation tools, patched binaries, copied stores, disabled integrity checks or hand-edited signed data; they can create a second tamper condition.
Verification after correction
Repeat the operation that originally produced it, not merely a UI refresh. Confirm the exact product/object completes, review LicenseStatus and LicenseStatusReason when applicable, and check that no related boundary replaces it.
Regression testing, retain one failing fixture that reproduces “a kernel-mode policy-cache refresh produced data identical to the active cache, so no replacement was required” and one passing fixture that changes only the decisive precondition; this avoids mistaking a broad reset for verification.
