/* Wine "bootup" handler application
 *
 * This app handles the various "hooks" windows allows for applications to perform
 * as part of the bootstrap process. These are roughly divided into three types.
 * Knowledge base articles that explain this are 137367, 179365, 232487 and 232509.
 * Also, 119941 has some info on grpconv.exe
 * The operations performed are (by order of execution):
 *
 * Preboot (prior to fully loading the Windows kernel):
 * - wininit.exe (rename operations left in wininit.ini - Win 9x only)
 * - PendingRenameOperations (rename operations left in the registry - Win NT+ only)
 *
 * Startup (before the user logs in)
 * - Services (NT)
 * - HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServicesOnce (9x, asynch)
 * - HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunServices (9x, asynch)
 * 
 * After log in
 * - HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce (all, synch)
 * - HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run (all, asynch)
 * - HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run (all, asynch)
 * - Startup folders (all, ?asynch?)
 * - HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce (all, asynch)
 *
 * Somewhere in there is processing the RunOnceEx entries (also no imp)
 * 
 * Bugs:
 * - If a pending rename registry does not start with \??\ the entry is
 *   processed anyways. I'm not sure that is the Windows behaviour.
 * - Need to check what is the windows behaviour when trying to delete files
 *   and directories that are read-only
 * - In the pending rename registry processing - there are no traces of the files
 *   processed (requires translations from Unicode to Ansi).
