Lee,
I have been investigating this API function. As you allready know, it is
only used in the "Device Manager". However, you should be aware that there
are a few problems with this API:
1. Before calling this API, there is a long laundry list of processing that
must be performed by the calling program.
Validating Registry Entries
OS Version information
Matching Device ID's in specific registry Locations
Validation of the rolled back driver package
and more...
2. Currently this API will only work for Windows XP and Windows 2003, and
I've been told that it will change for Future versions of the Operating
System.
3. It will only work on those packages that have been saved to the registry
location:
SOFTWARE\Microsoft\Windows\CurrentVersion\Reinstall\...
4. I don't think there are any public API's that support the "Archaival" of
previous driver installation packages. Drivers that are updated through
Windows Update should have this done.
The real question is why do you want to have this done? I'm sure that your
current driver installation package doesnt have support for the archival of
existing driver packages during upgrade, so I'm not sure when someone would
call the API function RollbackDriver().
Anyways, I can release a development package to you that would allow you to
"Rollback Drivers", however, we feel that it would be too difficult to
release the details of the Specific API RollbackDriver() due to the
limitations listed above. If you wish to continue, the development package
would most likely come in the form of a *.lib or *.exe program. It would
take me another week or two to get it ready for you.
If you wish to continue, we should take this offline, and comminucate
directly.

Hi Keith,
Any update on this one?
