VBoxProxyStub.c@ 104507

Last change on this file since 104507 was 104154, checked in by vboxsync, 8 months ago
Main/VBoxProxyStub: Fixed using service start name when (re-)creating a (new) service via vbpsUpdateWindowsService() -- the service start name was used only to validate an existing service configuration, but not when actually (re-)creating the service if needed.
Property svn:eol-style set to `native` Property svn:keywords set to `Author Date Id Revision`
