I need to do a system restore because I installed a bad app in Vista
Ultimate but I get the following error. I would really appreciate some help
so I can get back to a stable state

Error:

System Restore did not complete successfully. Your computer's system files
and settings were not changed.

Details:
The writer experienced a transient error. If the backup process is retried,
the error may not reoccur. (0x800423F3)

Thanks,

Kevin
