● Let me look at the relevant source code to understand what's happening.

● Now I have the full picture. Here's what's happening:

  The /restart command (line 65-68 of SttwinService.dpr) does two separate
  calls:

  ElevScmStopService(service, not FindCmdLineSwitch('nowait'));   // stop
  ElevScmStartService(service, not FindCmdLineSwitch('nowait'));  // start

  The service was stopped, then StartService was called with wait=true. In
  InternalStartService (GpService.pas:254-264), it polls QueryServiceStatus
  every 100ms for up to 30 seconds waiting for the service to reach
  SERVICE_RUNNING state. After 30 seconds, the service still wasn't running, so
  it raised EGpService.Create(sFailedToStartService) at line 264.

  Two things stand out:

  1. The service took longer than 30 seconds to start. The uptime in the log is
  "1 minutes" which is consistent with this - the stop + 3-second sleep (if
  using ElevScmRestartService_Delphi) or just the cumulative time, plus the
  30-second timeout. The actual service process was likely still initializing
  (loading resources, connecting to databases, etc.).
  2. The exception is not caught properly. In ElevScmStartService_Delphi
  (GpElevationUtils.pas:483-484), only EOSError is caught. The EGpService
  exception escapes unhandled, which is why it becomes an application-level
  crash. If the timeout is a "soft" failure that should be returned as Result :=
   false, then EGpService should also be caught there.

  Root cause: The service didn't reach SERVICE_RUNNING within 30 seconds. This
  could be due to a slow initialization, a dependency not being available, or
  the service genuinely failing to start (stuck in SERVICE_START_PENDING).

  The bug: Even if the timeout is expected/tolerable, the code in
  ElevScmStartService_Delphi should catch EGpService alongside EOSError to
  handle this gracefully rather than crashing. Would you like me to fix that?

● Now let me check if ElevScmStopService_Delphi has the same issue.

  Searched for 1 pattern (ctrl+o to expand)

● Exactly as suspected — ElevScmStopService_Delphi (line 565, 572) correctly
  handles both EOSError and EGpService, but ElevScmStartService_Delphi only
  handles EOSError. Classic copy-paste oversight.

● Now let me check if there's a documentation file to update.

  Searched for 1 pattern (ctrl+o to expand)

● No docs file. The fix mirrors the pattern already used in
  ElevScmStopService_Delphi (lines 564-578): added EGpService to both the
  AutoLog.Exclude/Include calls and the except handler.

  This was a copy-paste bug — ElevScmStopService_Delphi correctly catches both
  EOSError and EGpService, but ElevScmStartService_Delphi was missing the
  EGpService handler. When the service didn't reach SERVICE_RUNNING within 30
  seconds, the EGpService exception escaped unhandled, crashing the process
  instead of returning false.
