Hi there
Well what does the registry key like dword:00000004 means?
What does that value 00000004 means?
Does it have unique meaning (fixed by Microsoft) or it depends upon software maker.

Is this a hexadecimal values??
Is there any thumb rule when dealing with registry? For Example if you want to disable write dword:00000001, if you want to activate something then write dword:00000002??

Regards

Welcome to BleepingComputer! I've requested for your topic to be moved to another forum for you.

The meaning of a doubleword value in the registry is determined by whatever software refers to that key. The value is hexadecimal - a doubleword is four bytes, 00 00 00 00 to ff ff ff ff value.

I don't think there's a general rule. A LSD value of 0 to 1 may toggle some functions, ie dword:00000000 to dword:00000001, but that may not be so in other cases. You need to know what the application (Windows itself or a program) is expecting.

Great minds like a think.

Hello :thumbsup:

A DWORD is simply a 32 bit integer numerical value.

Each registry value is simply a numbered setting. What each number means is controlled by the process that actually cares about the value you're looking at.

A more general explanation of WORDs as far as computers are concerned can be found here:

Hope that helps!!
