A new PC with Vista HP SP1 did not have this key in the registry:
Ten of the 20 tweaks depend on the presence of that key. Those 10 failed to apply.
Furthermore, after the attempt, this key appeared in the registry:
Or perhaps that was an error in the OEM's distribution?
To test that, I removed the ridiculous key and tried the apply again.
This key was in the registry: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies
Adding the Explorer key below the Policies key allowed the 10 tweaks to apply successfully.
