DESCRIPTION:
Cesar Cerrudo has reported two vulnerabilities in Microsoft Windows,
allowing malicious, local users to escalate their privileges.

1) The vulnerability is caused due to an unchecked buffer in the
handling of data sent through a LPC (Local Procedure Call) port. This
can be exploited to cause a buffer overflow and lead to execution of
arbitrary code with elevated privileges.

2) The vulnerability is caused due to an error in the validation of
identity tokens in LSASS (Local Security Authority Subsystem
Service). This can be exploited to gain elevated privileges.

SOLUTION:
Apply patches.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
