The automatic update from Microsoft KB2286198 was not successfully installed. I tried to uninstall it in the table of the list of updates. The uninstall process was running end ended with the ask to restart the computer. After the answer "yes" the system began the log-off procedure. After some second was "Pleas, don´t switch off the computer. The necessary data are collected." displayed on the blue screen. The wheel indicating the running of the log-off procedure stopped the the cycling. After about 1 hour switched I off the computer with the ON/OFF button. Then after the new start, the system sent many times message, that the program written on the message frame couldn´t start due to system violation 0xc0000005. Then could I not start all programs using the Windows Explorer include the Control Panel. Only the internet browswers can I open. What can I to do?
