Which command-line utility can the technician use to register or unregister DLLs and ActiveX controls?

Show answer & explanationAnswer & explanation
Correct answer: A. REGSVR32
REGSVR32 is a command-line utility in Windows used to register and unregister DLL (Dynamic Link Library) files and ActiveX controls in the Windows Registry. This can resolve issues where applications cannot find or properly interact with their required components.
Why the other options are wrong
- B. DISKPART is used for disk partitioning and management, not for DLL registration.
- C. REGEDIT is the Registry Editor, used for manually viewing and modifying the registry, but not for registering DLLs via command line.
- D. MSCONFIG (System Configuration) is used to manage startup programs and services, not for DLL registration.
