This tutorial will show you how to quickly generate a new Globally Unique Identifier (GUID) in Windows 10 and Windows 11.

A GUID is a 128-bit integer (16 bytes) that can be used across all computers and networks wherever a unique identifier is required. Such an identifier has a very low probability of being duplicated.

GUIDs identify objects such as interfaces, manager entry-point vectors (EPVs), and class objects. A GUID is a 128-bit value consisting of one group of 8 hexadecimal digits, followed by three groups of 4 hexadecimal digits each, followed by one group of 12 hexadecimal digits. The following example GUID shows the groupings of hexadecimal digits in a GUID: 6B29FC40-CA47-1067-B31D-00DD010662DA

GUIDs are remarkable. As Wikipedia says, "For example, consider the observable universe, which contains about 5 x 10^1022 stars; every star could then have 6.8 x10^1015 universally unique GUIDs."

The number of grains of sand on Earth is estimated at 7.5 x 10^18.
