I am having trouble deleting Registry Keys in Windows 2008 R2. (Windows 2003 is lets you delete the same keys). Am logged on as Administrator and have also right clicked the exe to Run as Administrator.
For example, using Regedit, Regedt32, PsTools PsExec and Windows PowerShell all give Permission Denied Messages when Deleting the key:
HKLM\System\CurrentControlSet\Enum\FTDIBUS
Which contains USB to Serial Devices that I want to remove. I get "Cannot delete 'keyname:' Error while deleting key." Permissions can also not be changed. Applies to the whole Enum key tree.
I'd appreciate anyone being able to tell me how to delete these device keys in Windows 2008 R2.
