修改服务 {serv_name} 的 DisplayName 信息为 {serv_displayname} 失败！

Error message

修改服务 {serv_name} 的 DisplayName 信息为 {serv_displayname} 失败！

What it means

Thrown in Com_ServiceOS.Config.Modify.DisplayName when the `sc config ... DisplayName=` stdout lacks the success markers 成功/success (Com_ServiceOS.cs:427-434). This is the genuine sc rejection path; most often access-denied from a non-elevated caller. The throw is caught by DisplayName's catch and it returns false (Com_ServiceOS.cs:441-445).

Solutions

Run elevated; sc config requires administrator privileges.
Avoid reserved/illegal characters in the DisplayName value.
Check the bool return and the logged sc output for the exact error.
Retry after elevating; confirm with `sc qc <name>`.

Example fix

// before
Com_ServiceOS.Config.Modify.DisplayName(name, display);

// after
bool ok = Com_ServiceOS.Config.Modify.DisplayName(name, display);
if (!ok) { /* elevate and retry; see log for sc error */ }

Defensive patterns

Strategy: validation

Validate before calling

bool ok = Com_ServiceOS.Config.Modify.DisplayName(name, display);
if (!ok) { /* elevate and retry; see log for sc error */ }

Prevention

Run elevated; sc config requires administrator privileges.
Avoid reserved/illegal characters in the DisplayName.
Check the bool return and the logged sc output for the exact reason.
Confirm with `sc qc <name>` after a successful change.

When it happens

Trigger: Calling Modify.DisplayName without admin rights (sc config requires elevation), or with malformed arguments that sc rejects.

Common situations: Non-elevated service-management tool; DisplayName containing characters sc rejects; reconfiguration during SCM busy state.
