To disable a device
Open Device Manager
Double-click the type of device that you want to disable
Right-click the specific device you want, and then click Disable.
If you disable a device that is required to start the system, such as your floppy disk drive or DVD/CD-ROM drive, these devices will not work, and your system might not start.
You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
To open Device Manager, click Start, and then click Control Panel. Click Performance and Maintenance, and then click System. On the Hardware tab, click Device Manager.
When you disable a device, the physical device stays connected to your computer. The drivers are available again when you enable the device. It can be useful to disable devices if you want to have more than one hardware configuration for your computer, or if you have a portable computer that you use at a docking station.
After you disable a device and restart your computer (if necessary), the resources allocated to the device are free and can be allocated to another device.
If you are not an administrator or a member of the Administrators group, you can use Run as to perform certain administrator functions. For more information on how to use Run as, see Related Topics.
Some devices cannot be disabled.
