CrypKey is a licensing and encryption software that installs an application called NetworkX through ckldrv.sys. Users can find the file saved on the computer in the following file path: C:\Windows\System 32\ckldrv.sys. NetworkX uses the Python programming language, and the process can help users with source codes needed for software licensing and protection. CrypKey on the other hand, provides applications that will enable users to copy-protect their software to prevent illegal copying. Average file size is 30.91 KB. The file is also associated with Honeywell Win-Pak, as well as NStar Access Control Systems. Users who disabled the file were unable to use the applications associated with the two other software programs. The file has never been detected as a PC threat. However, there were some AV software that read the file as a virus, but this turned out to be because of conflicts with the two software, and not necessarily because it was an actual virus.

Most non-system processes that are running can be stopped because they are not involved in running your operating system. ckldrv.sys. is used by NetworkX, If you shut down ckldrv.sys, it will likely start again at a later time either after you restart your computer or after an application start. To stop ckldrv.sys, permanently you need to uninstall the application that runs this process which in this case is NetworkX, from your system.

After uninstalling applications it is a good idea to scan you Windows registry for any left over traces of applications. Registry Reviver by ReviverSoft is a great tool for doing this.

The ReviverSoft experts have not yet reviewed ckldrv.sys

A process usually a part of an installed application such as NetworkX, or your operating system that is responsible for running in functions of that application. Some application require that they have processes running all the time so they can do things such as check for updates or notify you when you get an instant message. Some poorly written applications have many processes that run that may not be required and take up valuable processing power within your computer.

We have not received any complaint about this process having higher than normal impact on PC performance. If you have had bad experiences with it please let us know in a comment below and we will investigate it further.

The first thing you should do if ckldrv.sys. is causing errors on your computer is to run a Windows registry scan with Registry Reviver If you are still seeing errors after this you should uninstall the program that ckldrv.sys, belongs to, in this case NetworkX
