RegDelete bug ? Deleting values from keys without write access rights

Recommended Posts

aleeksunder

Hello!

I've found some not obvious behaivor of RegDelete() function. So If we already have created registry key 'HKEY_LOCAL_MACHINE\SYSTEM\Test' _without_ 'value' in it. RegDelete() will will raise an Error with code = 1 ( according to documentation 1 means - Unable to open requested key ), instead of code = -2 ( unable to delete requested key/value ).

This code running under account without administrative right, will return @error = 1 even if 'HKEY_LOCAL_MACHINE\SYSTEM\Test' already existing key and no 'value' in it.

$i_regdelete_result = RegDelete( 'HKEY_LOCAL_MACHINE\SYSTEM\Test' , 'value' ) ; = 2
MsgBox( 0 , 'ERROR' , @error ) ; = 1

Maybe this is due to RegDelete() tries to open target key with write access and gets denied. So I thought that this is not so obvious as it can be. And naturally $i_regdelete_result must have 0 in this scenario ( according to documenatation 0 means Special return value of RegDelete when key/value does not exist )

The special return is when you have access successfuly to the key

which is not the case as you don't run i admin mode

For me AutoIT behavior is OK

The simple fix for me was to add "#RequireAdmin" at the top of the code. ^_^
