What is NBKeyScan.exe?

The genuine NBKeyScan.exe file is a software component of Nero BackItUp by Nero.
NBKeyScan.exe is an executable file that is part of the Nero BackItUp program, an application designed to backup up important data to Nero's cloud storage network. This process checks the authenticity of the user's serial key when the program is run in order to counter piracy. This is a critical component for Nero BackItUp and should not be directly removed. Nero BackItUp was originally a part of the Nero Burning ROM Suite, but later was sold as a standalone product. The product offers the backup utility for up to five computers and unlimited mobile devices including iOS, Android and Windows. The program can be assigned to automatically backup data from hard disks (USB & Internal HDD drives), CD/DVD/Blu-ray discs, network storage space and the cloud. Nero is a German software developer best known for their flagship disc burning software program, the Nero Suite. Richard Lesser founded the company in 1995 as Ahead Software GmbH but the company changed their name to Nero in 2005. Nero became quite popular after many OEMs (original equipment manufacturers) decided to bundle the suite with their hardware products. Nero is headquartered in Karlsruhe, Germany.

we can remove from start up then nothing will happen to windows
Nero Serienschlüssel Liveabfrage, wird bei legal erworbener Software von Nero (z.B. Nero8) meist wieder abgeschaltet. Bei illegalen Versionen bleibt dieser auch nach Deinstallation im System, auch zu finden unter msconfig/Dienste oder msconfig/Systemstart.
Auch wenn dieser Prozess kaum Ressourcen blockiert hat so wurde ein sehr lahmes Notebook wirklich spürbar schneller, nachdem NBKeyScan aus dem Autostart geworfen wurde. Bei ähnlichen Problemen kann dies mal probiert werden (msconfig - Systemstart - NBKeyScan)
Its a program from Nero for backitup process

Nero BackItUp process, harmless, sounds like some kind of keylogger though.

Best practices for resolving NBKeyScan issues

A clean and tidy computer is the key requirement for avoiding problems with NBKeyScan. This means running a scan for malware, cleaning your hard drive using cleanmgr and sfc /scannow, uninstalling programs that you no longer need, checking for Autostart programs (using msconfig) and enabling Windows' Automatic Update. Always remember to perform periodic backups, or at least to set restore points.

Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or, for Windows 8 and later versions, executing the DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.

To help you analyze the NBKeyScan.exe process on your computer, the following programs have proven to be helpful: Security Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries.
