What does HRESULT 0x80290210 (TBSIMP_E_NOT_ENOUGH_TPM_CONTEXTS) mean?

TBSIMP_E_NOT_ENOUGH_TPM_CONTEXTS

The underlying TPM context capacity is insufficient

TBSIMP_E_NOT_ENOUGH_TPM_CONTEXTS (0x80290210) means virtualization needs another TPM context slot but available TPM/context-manager capacity is exhausted. It differs from the number of client-side TBS contexts.

Evidence to capture

Record loaded TPM contexts/resources, virtual-handle mappings, context-save/load pressure, and operations that should release TPM state.

Focused correction

Flush/release unneeded TPM resources or serialize work so context capacity becomes available. If client TBS contexts themselves are excessive, address TBSIMP_E_TOO_MANY_TBS_CONTEXTS instead.
