What is this driver?

Evgeny Moryakov : This is the driver TAP-Windows Virtual Network Driver, in my case this device appeared after using the program KMS to activate the program, on this device driver as I understood to put not real because it virtually connects the program and activates some software, a lot read about it and came to the simple and briefly just removed this device driver for it not to put.

Moderators of the forum : Tell us in more detail, what "program" did you activate KMS? Which OS is installed on your device? How did you acquire it? Tell me, don’t be ashamed.
