This is a critical component for Nero Burning ROM and should not be directly removed. Nero Burning ROM is a utility program created for the Windows platform, originally for authoring optical discs such as CDs and DVDs. The first version was released in 1997 and has been released through ten new versions ever since. Different versions of the software such as Nero Burning ROM Lite were released as cheaper alternatives with limited functionality and features. Nero Express was targeted at entry-level audiences. It showcased a friendlier interface making it much easier to use. 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.

Best practices for resolving NASvc issues

A clean and tidy computer is the key requirement for avoiding problems with NASvc. 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 NASvc.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.
