How to get the computer GUID and SID

From time to time you might need to get your computer GUID and/or SID.

You can read down and see how to retrieve these values from your computer.

Computer GUID

To get the GUID of your computer you can download a tool called SIW. This is not a program you have to install to run.

Click on Operating System and you will find the computer GUID there.

Computer SID

Download NewSID from Microsoft and run it. NewSID is a tool to change the computer SID and is used with cloning of computers. The SID has to be unique within a network.

You will see the current SID when you can specify what to change it to. Do not change your SID.
