A year or so ago I asked for help because when I right clicked on "start", "open" and "explore" were greyed out.
I was given the answer, but like a pillock, I didn't make a note of it ('cos it's unheard of for Windows to have more than two faults in a year
) and I can't find the thread.
As you'll already have guessed from the title of this thread, it's happened again.
If someone would be so kind as to re-answer, I promise to write it down on a big piece of paper and not bother you again.
