What Is a GUID?
A GUID (Globally Unique Identifier) is Microsoft's name for the same concept as a UUID — a 128-bit value used as a unique identifier — traditionally written wrapped in curly braces and in uppercase, such as {3F2504E0-4F89-11D3-9A0C-0305E82C3301}, the format expected by many Windows and .NET APIs.
This tool generates the same underlying random 128-bit value as the UUID Generator, but defaults to the classic GUID formatting so it drops straight into a .NET project, a Windows registry key, or a COM component definition without needing manual reformatting.

팁
Keep Braces for Registry Entries
Windows registry GUID keys typically expect the curly-brace format.
Drop Braces for Code Constants
Some .NET APIs accept a plain, unbraced GUID string — disable braces if so.
