Safe next steps

  1. For 4431 (ERROR_SECUREBOOT_POLICY_ROLLBACK_DETECTED), check which account and application reported the code, and whether the account is permitted to perform that specific action.
  2. Use the official account or organization recovery path. Do not share passwords, tokens, product keys, or recovery keys with a code-lookup site.
  3. For a work or school device, ask IT to inspect policy and audit logs before changing permissions.

After one step, repeat the original operation and record whether this same code returns. A different code needs a fresh interpretation.

Stop before changing security, licensing, directory or production settings on a managed device; involve the responsible administrator.
