guid.exe [parms]

generates a globally unique identifier (GUID) using windows api functions,
displays it as a string, and copies it to the clipboard.

you can use pipes to redirect the output (won't redirect the "copied to clipboard" text).

parms can be any combination of:

 u      - uppercase output
 k      - enclose output guid in {brackets}
 0-9a-f - generate a guid that begins with this specific hex character

e.g. "guid duk"
will generate something like: {D9315325-57CA-4165-94FD-D6620E960BF4}
