Disabling Unneeded Hardware Devices
Disabling Unneeded Hardware Devices
One of the most time-consuming portions of the boot is loading all the hardware
drivers for your specific system setup. Every driver for each installed hardware
device must be loaded and then initialized by the operating system while the
system is starting up. Keep in mind that your computer has a lot of devices that
you do not always use. When Windows has to load all the extra hardware on
your computer, its performance is slowed down.
Although Windows 8 is more intelligent than previous versions about how it
loads drivers and devices, loading and initializing those devices still takes time.
In previous versions of Windows, the system would load one hardware device
driver and then load another device driver in a series. The problem with
loading the hardware this way was that it could slow down the boot dramatically
if one hardware device was taking a long time to initialize.
Windows 8 is similar to Windows Vista in the way it loads device drivers
and initializes the devices. Instead of loading the hardware device drivers in a
series, it now loads some of them in parallel. This allows the boot to be much
faster. Although the hardware devices are loaded in parallel instead of in a
series, the addition of more devices that the system has to load drivers for has
the potential to, and most likely still, slows down the boot.
Using Device Manager to Disable Hardware
Getting rid of extra hardware with Device Manager is an easy way to speed up
your boot. Follow these steps to disable your extra hardware devices:
1. Open the Start screen, type devmgmt.msc , and press Enter.
2. After the Device Manager loads, you can browse through devices
connected and currently running or disabled by browsing through the device
type sections. To disable a device, right-click the device name and click
Disable.
3. To re-enable a device, right-click the device name and click Enable, as
shown in Figure 13-6. This removes the check mark from the menu and
re-enables the device.
TIP To determine the status of a device, check out the icon next to its name. All
devices that are disabled have a down arrow over the icon. All devices that have a
question mark or an explanation point on them are not set up correctly or are
having problems. All devices with none of these additions to the icon are running—
and doing so without any problems.
