SDIAG_E_DISABLED
SDIAG_E_DISABLED means that Windows policy prevents scripted diagnostics from running, regardless of whether the troubleshooting pack itself is valid.
Where the failure sits
A troubleshooting pack has distinct initialization, detection, resolution, and verification phases. Keep the ordinary result report together with the debug report, and identify whether the pack script, PowerShell host, managed host, resource loader, trust check, or verifier produced the first failure.
Administrative elevation does not override an explicit enterprise policy that disables the feature.
Facts to collect first
- Effective Group Policy/MDM setting, scope, source GPO, and refresh time
- WTP/MSDT invocation, pack identity, and system edition/build
- Diagnostic Policy Service and related host state
- Policy result report such as gpresult/MDM diagnostics
Change one variable at a time
- Run a built-in non-scripted diagnostic if available.
- Test the pack on a policy-equivalent lab machine after changing only the controlling setting.
- Force policy refresh and confirm the effective value before retrying.
Verification after correction
The corrective action should be narrow: Change policy through the authorized management channel or use an approved replacement diagnostic workflow.
Close the incident only when effective policy reflects the intended scope, the pack runs only where permitted, and disallowed devices remain blocked.
