Metro is still in: Windows 8 security model

Security mode is a life-saving straw for Windows systems and a favorite of the masters. Windows 8 has also been greatly enhanced in this regard. Let's take a look at the new security model for Windows 8.

The following tests are based on the Windows 8 x64 Developer Preview and the HP Touchsmart TX2 Notebook.

1. To quickly call up the Windows 8 security mode and other menus at boot time, the shortcut keys are not the traditional F8, but replaced with S hhift+F8.

It can be seen that Windows 8 provides more boot options, including normal security mode, network security mode, command prompt security mode, enable boot log, enable low resolution, debug mode, disable automatic when system fails Restart, disable forced driver signature, disable pre-boot security software driver.

3, Windows 8 security mode login is a traditional desktop, not the Metro interface, but the Metro interface still exists, and can be used, press the Win button on the keyboard or the desktop or the Win icon in the lower left corner Accessible.

4, Metro operation feel very bad in safe mode, effects Caton obvious. When you slide the Metro quickly, you can compare the CPU usage of the memory, 2.2G, 50% in the safe mode, 0.55G and 10% in the normal mode. It is speculated that the effects of Windows 8 sliding, fade, and acceleration slowdown are all accelerated by the GPU. In the safe mode, the GPU driver is not loaded and can only rely on the CPU, resulting in high CPU usage.
