title: When will windows uuid change on the same system
body: <p>I'm wondering about what the Windows UUID that you can get with "wmic path win32_computersystemproduct get uuid" really comes from and when it will change. Microsoft says, the UUID comes from the SMBIOS information (<a href="https://msdn.microsoft.com/en-us/library/aa394105(v=vs.85).aspx" rel="noreferrer">https://msdn.microsoft.com/en-us/library/aa394105(v=vs.85).aspx</a>), what seems to me that the UUID only depends on the system's BIOS. So what when I do one of the following things:</p>
  
  <ul>
  <li>(a) Reinstall Windows on the same system</li>
  <li>(b) Install a second Windows on the same system</li>
  <li>(c) Clone windows to another disk and then use this disk in the same system</li>
  </ul>
  
  <p>Will any of this actions make the UUID to be changed? Or is it possible to have to different Windows systems with the same UUID (b)?</p>
  
  <p>Thanks a lot</p>
