Answer 1

You could change the permissions of the key in Regedit but this might prevent the key from working, so back up the key before attempting this.

• Right-click and select Permissions...
• Click the Advanced button.
• If you're not the owner, click Change and take ownership.
• Click Disable inheritance button.

Continue through the dialogs, and the Registry object will be fairly well protected... though it is possible a system process could change the value, despite these restrictions.
