The operating system of my laptop is Windows 8 64 bit. And now I want to uninstall the SP1 Beta. I have tried the following ways, but they are useless. I really do not know why. There is no uninstallation button in the updating list of installation. I try to uninstall it by double click ot right click. There is no response. Then if I try the command line uninstalltion, it indicates tha the updating has been used by the system, so it can not be uninstalled. Therefore, I do not know what should I do, and what I can do now.
I'm counting on your help.
Thanks a lot!
