On Vista SP2 x64
Using a bat/cmd file

Using this code:
Code: [Select]reg delete HKLM\HARDWARE\DEVICEMAP\SCSI /f
Getting this error:
Code: [Select]ERROR. Access is denied.
I never had problems with this, when using XP. Perhaps this is Vista TRYING to prevent malicious activity. My user is in the group "Administrators". Any thoughts?

I must select to run as Administrator, then everything works fine -this even though my user account IS part of the Administrator's group.

From what I've gathered, Vista's UAC/Application's Manifest will run many programs with a lower level token -even when you are part of the Administrator's group. So I take it, that in order to delete registry keys, cmd.exe must be run with elevated rights. Which of course leads to another problem of having to manually select to run as Administrator every single time I use the batch file. I could check the "Run this program as administrator" check box, however I cannot since it is grayed out -which is another story in itself. Wish something, anything, would just be simple!
