I have lost the ability to use internet options from the tools menu in IE. Message is:This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator. I am the only user and think this may be tied to following event:Windows saved user David-xxxxxxxxx /Home (me) while an application or service was still using the registry during logoff. The registry will be unloaded when it is no longer in use. Also stated was this: This is often caused by services running as a user account. Try configuring services to run in either the local services or network services account. I went to windows event website and it said no action required.. Other things going on are as follows: Defrag stops at 5% and will not complete. And Getting bad block errors continually in system event log....Hard drive is but a year old should this be going bad so soon Western digital 8 gig???
