/* Based on the Wine "bootup" handler application
|
|
*
|
|
* This app handles the various "hooks" windows allows for applications to perform
|
|
* as part of the bootstrap process. Theses are roughly devided 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, ?semi-synchronous?, not implemented yet)
|
|
* - 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?, no imp)
|
|
* - 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).
