SL_REMAPPING_SP_PUB_KM_CACHE_POLICY_CHANGED
What this Software Protection result isolates
0x4004D602 maps to SL_REMAPPING_SP_PUB_KM_CACHE_POLICY_CHANGED. 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, policy changes that require reboot were detected while preparing the kernel-mode licensing cache.
the first result diagnostic fork is precise: the cache update can be valid even though enforcement cannot fully switch until reboot.
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 changed policy identifiers, old/new cache generations and reboot-pending state.
Servicing tools can repair protected system files, while unofficial replacements, patchers or permission resets can create a second mismatch and destroy provenance.
Checks in the useful order
- Record this result,
0x4004D602, the exact API or service operation, and the affected product or protected object. - Prove the specific condition: record changed policy identifiers, old/new cache generations and reboot-pending state.
- Compare the neighboring results below and identify which condition actually applies.
What to capture before recovery
- SFC/DISM results and Security-SPP event correlation
- exact module/file and version
- digital signature and file hash
- OS build and servicing level
- kernel-cache policy generation and reboot state
Why the symbolic code matters
| Result | Different condition |
|---|---|
SL_REMAPPING_SP_PUB_KM_CACHE_IDENTICAL | Compared with this result, a kernel-mode policy-cache refresh produced data identical to the active cache, so no replacement was required. |
SL_REMAPPING_SP_PUB_TAMPER_MODULE_AUTHENTICATION | Compared with it, 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.
Correcting the producing condition
Schedule a controlled reboot and verify the new policy/cache generation afterward.
Representative case: A servicing update changes boot-time licensing policy while the system remains running.
