1. Open Start.
2. Search for regedit and click the top result to open the Registry.

3. Browse the following path:

   HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP

   Quick tip: On Windows 10, you can now copy and paste the path in the Registry's address bar to quickly jump to the key destination.
