Ray--after I running Reg Vac (which I love!), I can access time zones or save entries into the Outlook Calendar.  Here is the error message: 'Could not save item. out of memory or system resources. close some windows or programs and try again'.  By the time I figured it out that something had been deleted, it was too late for the UNDO.  Any suggestions?  This was suggested on one site, but I don't understand how to do this.  THANKS!

Make an export from an good working computer with Vista installed from the "TimeZone" folder found in:
HKEY_LOCAL_MACHINE
|_ SOFTWARE
|__ Microsoft
|___ Windows NT
|____ Currentversion

Import this registry-export-file in the damaged computer, restart, and everything works fine again!

   The Time Zones are only cleaned in the Expert Zone of RegVac and only if you purposely removed them.  RegVac does not remove them by default.
   Go to Run and type, "regedit".  Then you can find TimeZone in the above location.  Select it and find Export in the File menu at the top of RegEdit.  This will save the settings in TimeZone in a reg file.  Put that file on a CD or transfer that file some other way to your computer.  Double click on the reg file on your computer and it should be entered into your computer's registry.
