Dynamic Link Library (DLL) files are files that are stored on your computer and allow programs to share code in order to perform certain tasks. The majority of DLL files are needed to run programs on your computer, but there are some malicious programs that consist of DLL files that can damage your computer or can allow intruders to gain access to your machine. DLL files must be unregistered from the registry before being removed. Here are two methods to unregister and remove unwanted DLL files.

Advice

  • Once you are absolutely sure that you have deleted an unwanted DLL file and your computer has no issues, you can safely delete the backup DLL file that was saved on your computer.
  • Make sure to always back up the file you want to delete. If you find that you have mistakenly deleted the incorrect file and essential programs stop working, you will be happy to have a backup.
  • Always unregister a DLL file before removing it. If you just delete it, your computer will think it still exists unless it has been unregistered first.
