cores in multicore processors to process and decompress hiberfil.sys, the system starts much more
quickly (typically 30-70% faster) than with previous Windows versions.
If you need to add or remove hardware from a system, you can change the behavior of Windows 8's
shutdown and startup process by using the Shutdown.exe program from an elevated command prompt.
This command triggers a full shutdown:
shutdown /s /f /t 0
When the system restarts, it does so using the cold boot process.
To disable hibernation (which also disables fast startup), use this command from an elevated
command prompt:
powercfg -h off
If you have disabled hibernation/fast startup, use this command to revert the system to the default Fast
Start behavior after shutdown:
shutdown /s /hybrid /t 0
When the system restarts, it does so in the default Fast Start mode.

PC Maintenance Tools
To troubleshoot and repair PC systems properly, you need a few basic tools. If you intend to
troubleshoot and repair PCs professionally, there are many more specialized tools you will want to
purchase. These advanced tools enable you to more accurately diagnose problems and make jobs
easier and faster. Here are the basic tools that should be in every troubleshooter's toolbox:
• Simple hand tools for basic disassembly and reassembly procedures
• Diagnostics software
• A multimeter
• Chemicals (such as contact cleaners), component freeze sprays, and compressed air for
cleaning the system
• Foam swabs, or lint-free cotton swabs if foam isn't available
• Small nylon wire ties for “dressing” or organizing wires
Some environments also might have the resources to purchase the following devices, although they're
not required for most work:
• Memory module tester
• Serial and parallel loopback (or wrap) plugs to test serial and parallel ports
• A USB testing plug to test USB ports
• A network cable scanner (if you work with networked PCs)
