How to delete windows registry values from PnpLockdownFiles key?

Question

How to delete registry values from HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Setup\PnpLockdownFiles key?

When I try to do it with regedt32, I get "Unable to delete all specified values" error message.

This key contains file's paths. So as I understand first I should "unlock" them. But actually files that I want to delete does not exist.

1. take permissions for your user;
2. remove entries;
3. take back permissions.
