Every time you connect a new device to your computer, Windows automatically installs the appropriate driver and, if necessary, adds a new entry to the system registry.

This is done so that in the future the system can quickly identify the desired device and in most cases this behavior is not a cause for concern. However, over time, a large amount of information about "ghostly" devices connected to a PC only once accumulates in the registry. Records about these devices increase the size of the registry, thereby prolonging the time of computer startup and adversely affecting the performance of the system as a whole. The utility called GhostBuster will solve the problem.

Just run the GhostBuster program, and a few seconds before your eyes will be a detailed list of familiar hardware systems with separately marked "ghosts." If the device name is not sufficient for its unmistakable identification, you will find useful additional information in the "Device and Description" column.

If an excess device is detected, right-click on it and select the Add Device option from the context menu, and the "Add Class" item allows you to mark an entire class of devices. The candidates for removal will be highlighted in red. If you make a mistake and found it in time, cancel the action with the "Remove Device" or "Remove Class" option.

After you have noted all the necessary devices, create a system restore point. This protection mechanism will avoid possible problems in the event of accidental deletion of important devices (however, complete security is guaranteed only by creating a full backup of the system and the presence of the Windows installation disk). After all the precautions have been followed, click on the "Remove Ghosts" button, and all "ghosts" will be immediately ejected from the computer's memory.
