TBSIMP_E_TOO_MANY_RESOURCES
Technical interpretation
TBSIMP_E_TOO_MANY_RESOURCES (0x80290218) belongs to TBS resource virtualization. The base What Is page already shows the short Windows message; the additional diagnostic value is that this result marks the internal virtual-resource inventory has reached its allowed limit.
The first producer to identify for it is the TBS context and virtual-resource manager that maps finite TPM slots for multiple clients. TBS resource virtualization maps client-visible virtual handles to finite physical TPM key, authorization and transport slots. Cleanup, eviction and context ownership determine whether a mapping can be restored.
Inputs and state to capture
Preserve these this result items before changing anything:
- This result and
0x80290218, the exact returning method or command, and the first nested status. - resource count by type and context, create/load/flush balance, long-lived handles, process owners, and service uptime.
- The TPM generation, manufacturer/firmware revision, Windows build, caller identity and TBS/provider state for it.
- The complete opaque request artifacts, redacting authorization secrets but not rewriting structure boundaries.
Validate without broad changes
Run this focused check: flush one disposable object and verify that one new resource can be virtualized. Do not combine the result test with firmware updates, TPM clearing, account changes, key recreation and policy edits in the same trial; such a result cannot isolate this boundary.
| Checkpoint | Pass condition |
|---|---|
| the internal virtual-resource inventory has reached its allowed limit | The original this result command reaches the next defined state without returning it. |
| Security behavior | The result verification still uses the intended TPM, authorization, locality and policy. |
| Output integrity | The object, digest, event log or state transition produced after it validates independently. |
Neighboring response codes
| Related result | Separate meaning |
|---|---|
TBSIMP_E_TOO_MANY_TBS_CONTEXTS | A new TBS context could not be created because there are too many open contexts — a separate checkpoint when compared with it. |
TBSIMP_E_HASH_TABLE_FULL | No new entries can be added to the hash table — a separate checkpoint when compared with it. |
TBSIMP_E_NOTHING_TO_UNLOAD | No resources can be unloaded — a separate checkpoint when compared with it. |
The practical distinction is that TBSIMP_E_HASH_TABLE_FULL identifies the implementation data structure that may enforce a related limit.
Fix and verify
The supported direction is to release unused keys and sessions and redesign handle caching around operation lifetime. Do not confuse a TBS virtual handle with a physical TPM handle or copy it to another process. Resource virtualization intentionally scopes mappings to a client context.
If the same bytes still return it after the documented preconditions are satisfied, retain this code-specific trace for the platform vendor or Windows component owner rather than erasing state.
