How to disable a McAfee service?
- by AngryHacker
I am trying to disable a McAfee Real-Time Protection service, but if I go into Services/Properties, then try to set it to Manual or Disable - it says that 
  unable to open service McShield for
  writing on Local Computer. 
  Error 5.  Access is denied.
I've tried logging in as an Admin, to no avail.  I've tried resetting permissions in the registry to the key where the McAfee service is described...nothing helped.  Logging in with Safe Mode did not help either.
How can I disable this service?
Is there a way to disable a service before even getting into Windows?
P.S. Uninstalling McAfee is not an option.
