2. Your Accessories MENU can vanish. Not something Microsoft hammered down then welded in place. After this many years you should be quite a good Windows user to know how to make shortcuts but if not let's do another article. Read http://support.microsoft.com/kb/267951 and try that. If that fails, manually rebuild the menu.
I'm getting close to answers but do not want to mess with things that I am unsure of.
In Windows folder, I opened the Task folder which I know contains some of what is missing such as; Defrag, Disc Cleanup, etc. When I click on the properties of such task it tells me that it was modified AUGUST 20008 and opens with: UNKNOWN application.
The next thing I checked was Dr. Watson which tell me;
Windows KB891711 component has altered Windows system files.
Are they connected and is there a cure?
I really appreciate any feedback for this issue.
Thank you so much,
