Every time that comes time to generate GUID – I almost forget how to do this!
Here is the tool included in Visual Studio:
C:\Program Files\Microsoft Visual Studio 8\Common7\Tools\guidgen.exe
For simplicity sake, you could add this path to your system variable: PATH – just add : ;C:\Program Files\Microsoft Visual Studio 8\Common7\Tools
NOTE: After applying new value to the PATH variable – don't forget to re-open DOS window . After re-opening you will be able run the GUIDGEN.exe from wherever place you are in your disc!
