IUpdateInstaller4::Commit method (wuapi.h)

  • Article

Finalizes updates that were previously staged or installed.

Syntax

HRESULT Commit(
  DWORD dwFlags
);

Parameters

dwFlags

Reserved for future use.

Return value

Returns S_OK if successful. Otherwise, returns a COM or Windows

error code.

Remarks

The Commit API was made public in the 1809 SDK. Any app compiled with the wuapi.h header can use the Commit method on previous versions of Windows 10 as well.

Commit should only be called once. This call should happen just prior to commencing a reboot. Calling it multiple times prior to a reboot is not supported and may cause the update to fail.

Calling Commit is required prior to rebooting when a feature update is pending reboot. If Commit is not called in this circumstance the update won’t be finalized and installed during the reboot.

Commit is safe to call prior to reboot for any other types of updates as well.

Minimum supported client Windows 10, version 1507 [desktop apps only]
