Registry Editor.
b. Locate and right-click the registry subkey:
and then click Permissions.

for the following entries is selected:
• Full Control
• Read
e. Click Apply, and then click OK.
f. On the File menu, click Exit to quit Registry Editor.
Open the Registry Editor again and see if you can delete the key now.
If not, try this...
Start | Run | Type: regedit | OK |
Navigate to >>>
the said key
Right click the key in the left hand pane | Permissions... | Advanced
button | Owner tab | click the new owner and then click OK.

> The name, type, and data fields are all blank. I cannot delete or rename
