Answer
The technician should execute sfc /scannow from an elevated Command Prompt to replace corrupted system files, and use Device Manager to roll back the hardware driver to its previous stable version.
Executing sfc /scannow scans protected system files and replaces corrupted DLLs with intact cached copies. Using Driver Roll Back within Device Manager restores the working driver previously used before the problematic update was applied.
