I accessed the usb stickey and was going to edit my registry. I found items to delete but when I tried, I received error, To have permission you right
click and go to permission, I did then went to Advanced tab to add me in
for permission. Clicked area to edit, line blinking for letters to write. I could not spell or even just hitting a key like C would not register. Like my keyboard was broke. And it is mounted on laptop. Is there something I missed.
