Notes about the LKP 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 LKP file type is primarily associated with 'Systems Management Server (SMS)' by Microsoft Corporation. With SMS you can provide your organization a change and configuration management solution to deliver relevant software and updates to users of Microsoft and third-party applications.
