Get Rid of Unsigned Drivers

Signed device drivers and files have been tested by Microsoft and are deemed safe and compatible with the Windows 7 operating system. Those that are not signed might not be safe and might not be compatible. Unsigned device drivers and files associated with incompatible hardware and software is another area that can cause a computer to have a slow boot process, have a slow reaction time, or generally have unexpected performance errors (like a failure to come out of hibernation). This incompatibility can cause major problems, including unexpected shutdowns of applications, hardware that sometimes works and sometimes doesn’t, and hard-to-diagnose problems with the shutdown process (including the inability of the computer to shut down at all).
