Explanation

Note: The provided answer of FIXMBR is highly questionable for this scenario. FIXMBR (or 'bootrec /fixmbr' in modern Windows) repairs a corrupted Master Boot Record and is used when a system cannot boot at all-not when a browser application fails to open on a running system. The more appropriate answer would be SFC (System File Checker), which scans for and repairs corrupted Windows system files that could prevent applications like browsers from launching. If this question appeared on an older CompTIA A+ exam, the answer key may contain an error. In practice, use 'sfc /scannow' in an elevated command prompt to address application launch failures caused by system file corruption.
