I finally gave up(see long thread in security section) and just added another administrator on my pc. I have closed IE multiple times on this account and don't have the dreaded message about search providers, corrupted, etc. etc.
So, as I searched the internet, couldn't find exactly what I was looking for and thought I would try here:
Of course, all my files- music, itunes, pics, etc, are all on the original, corrupt adminis. account. What is the easiest way for me to transfer these files to the new account? Everything I have is backed up- is this the easiest way to go? I am a noob at all this stuff- simplier the better.
