Where is guid in registry

The closest thing to what you've described is the machine's SID, however this doesn't work for two reasons:. What do you need this identifier for? Your best bet may be to generate your own, if that is possible.

You could try the MAC address, which is at least intended to be globally unique and permanent. This would also have the nice advantage that you could obtain a machine's IP and hostname without too much bother and it wouln't be restricted to Windows either.

It wouldn't meet your requirement of being in the registry, but you can use WMI for it instead. How about the DriveId of the system volume?

Again there is no guarantee that it will be unique every time, or that it won't change. I think that the closest thing to meet your needs would be the MAC address, however that to could change if the NIC were replaced. Domain SID. Why not just use the computer name? Its going to be unique within your domain, all windows installations have one and will only change if a domain administrator changes it which should never be needed unless making a correction.

I, too need, to find a way to globally uniquely identify Windows installations. Firstly, in order to properly classify and identify backup images and determine which ones get recovered on which machines. Secondly, in order to name sychronization pairs for synchronizing files and to determine which synchronization pair to use depending on the machines involved in the synchronization. After reading several posts, including those on this website, I conclude that there is no easy way to find a globally unique identifier of a Windows installation.

That is too bad. Like the hardware, the software should also have its own serial number. Oh well! The above-mentioned formula is all I need for my purposes; I do not need the SID I presume that it signifies Security Identifier or something else more complex, because the combination of both variables references exactly the Windows installation that I need to identify, whereas each individual variable is, on its own, of no use to me.

Specifically and firstly, the Windows product identification is identical on computers made by the same manufacturer and found in the same product line and that serves me no purpose, since I own several identical machines. Secondly, the serial number is not uniquely identifying enough, since I do have several Windows installations on one computer that a computer serial number does not address.

I therefore suggest my method. Also, and before you inquire about it: I chose not to base my method on the computer name. The information is user-based and therefore needs to be inventoried.

However, the Windows product identification and the computer serial number are already identified, inventoried and invariably connected to two specific products, thereby eliminating the need to inventory them again.

I would neither elect to identify a Windows installation with a unique identifier of hard drives, since I am able and quite apt to switch them around from one machine to another, especially when drive capacities are in a state of constant flux. By the same token, I would much less use the identifying nomenclature of either the central processing unit or the motherboard, as has been heretofore suggested in a previous reply by Shoeless.

Finally, I also reject the most obvious option of identifying a Windows installation although it has not been mentionned by anybody else from what I can see : using the product key.

Although it is unique, it is only a license to install a certain version of Windows; it is not actually connected to a particular Windows installation and it does not distinguish it as being installed on a particular machine, even though the license was granted by virtue of the purchase a given computer.

If available, it will trigger the repair function of the installation, possibly resetting things. It's also incredibly slow compared to parsing the registry.

Nice work Adam. Can this be revised to enter a vendor name instead to ensure I get all software from the same vendor and can it be run on a remote computer? I just realized not all software display names have the vendor name. Your email address will not be published.
