Do you have speed issues?
First check your registry for invalid entries.

Notes about the DLL file extension:

Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.

The DLL file type is primarily associated with 'Dynamic Link Library'. A .DLL file is a support file and is used by one or more programs. As an example, if several parts of a program need to perform the same action that action may be placed into a .DLL file (library) that the various program parts can all use. This saves space and makes it easier when that particular routine needs to be updated. You should never have a need to "open" a .DLL file on its own; indeed, there really is no way to do so. Note: This file type can become infected and should be carefully scanned if someone sends you a file with this extension. If you want to look at the resources in a DLL library you can use a program like XN Resource Editor but BE CAREFUL as messing with a DLL file can seriously damage Windows or programs if you do the wrong thing.
