Batch, Registry & UAC

Hi all,

I've written a batch file which adds registry keys (with dynamic driveletter recognition) upon startup, launches a program and deletes the keys when closing the program.

My only concern now is that when launching the batch, I get a UAC dialog for the registry changes.

Is there some way I can tell Windows through the batch file that I really don't need any dialog (for this file only)?

I don't know anything about the creation process of EXEs, but I've never seen any UAC for registry changes made by EXEs...? So it has to be possible I guess...

Thanks!

Hi Propa,

It depends where you write these keys, if your just using the HKCU (Current User) hive then you wont need UAC elevation, however every other hive will result in a UAC prompt

Ok. I got some sort of breakthrough...

If I run the batch as Administrator, none of the dialogs appear, but running cmd as Administrator also changes the initial working directory.

This is fixed by inserting cd /d %~dp0 to the very beginning of the file (or just after @echo off).

So now I don't have registry dialogs anymore, but I have to select Run as Administrator & confirm...

Any other ideas to completely hide all dialogs?

Do you have to have the BAT file create the REG file?

Yes, the bat file catches the working driveletter, which is necessary for the registry keys.

Got it!

Instead of calling REGEDIT, I need to call REG(.exe), which doesn't interfere with UAC.

So

Code:

START /WAIT REGEDIT /S

becomes

Code:

REG IMPORT

Ok I understand now. Yes there is a way to make it work transparent however the Batch would need to be converted to VBScript. It would take a bit of time to convert it and then add the extra code to make it work as you need it. I have a lot of the code already written (saved somewhere, I need to look for it).

I don't have the time tonight to re-write it and then I don't have the means to test it. Maybe if no-one here comes up with a better idea I can look at it over the weekend. I will keep re-viewing this thread.

Got it already. See my previous post.
