Hi Guys
i was trying to remove HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\WMI\Autologger compleetly,
but  2 cellcore & about 20 NetCore seemed to be undeletable the normal way
i found these items back into HKEY_CLASSES_ROOT , again they were undeletable the normal way.
so i deleted them with RegistryWorkshop  
i saw a bunch of items and decided to remove them to see what was going to happen.

all of them below
all HKEY_CLASSES_ROOT\System.Runtime.Remoting
 WinInet 4 items
HKEY_CLASSES_ROOT\WBEMComLocator all
HKEY_CLASSES_ROOT\Workspace.all
HKEY_CLASSES_ROOT\IAS*  all
X509Enrollment.*
Search*
HKEY_CLASSES_ROOT\PLA-
I made each time a backup of my Windows.
After removing nearly 200 items in HKEY_CLASSES_ROOT Windows was still working , no problems
So why all these items ? , how many more can be removed without breaking Windows down ?
