Question

The user does not have time to reimage the computer, nor do they wish to remove and reinstall the application. Which of the following should the technician do FIRST?

  • BOpen Task Manager and stop all running SERVICES processes
  • COpen up MSCONFIG and remove the application from the start-up tab
  • DOpen a command prompt and type REGSVR32 SYSMAIN.DLL ?U

Explanation

SFC /SCANNOW (System File Checker) scans all protected Windows system files and replaces corrupted or missing ones with cached copies. Since the symptoms - system file errors and broken shell functions like right-clicking - indicate that the application installation corrupted or overwrote core Windows files, SFC is the appropriate first step. It is non-destructive, does not touch the newly installed application, and can repair the damage without a reimage. Stopping services in Task Manager won't fix corrupted files; removing the app from MSCONFIG startup won't restore damaged system files; and REGSVR32 with the /U flag unregisters a DLL, which would make things worse.
