|(a) taskbar and start menu disappeared. (b) nothing happened when i clicked "help and support"; it can't be opened/ accessed. (c) "paste" is disabled (greyed out) at the right-click menu, which means copy-paste is not working (chrome is the default browser). (d) the sole user name was found changed/ replaced by "699F01E77B5046D", and now i have no access to the user profile. At the "User Accounts", there're two tabs- "Back" and "Home"; i clicked and clicked at both but nothing happened. however, the computer can still be opened and shutdown.|
It's windows XP.
