Microsoft Windows 98 Case Studies & Practical Application 4

Question 1

A Windows 98 computer running a legacy DOS accounting application crashes with 'Insufficient memory' despite having 128 MB of RAM. What Windows 98 feature governs memory available to DOS applications?

Accepted Answer

DOS Memory (conventional memory below 640 KB)

Answer

Legacy DOS programs are constrained to the first 640 KB of conventional memory; Windows 98's memory manager uses UMBs and EMM386 to maximize available conventional RAM.

Question 2

You are configuring Windows 98 for a kiosk that must auto-restart daily. Which built-in Windows 98 utility allows you to schedule an automatic restart?

Accepted Answer

Task Scheduler (Scheduled Tasks)

Answer

Scheduled Tasks (formerly System Agent) in Windows 98 can run scripts or applications at set times, including a batch file that calls 'shutdown -r' equivalents.

Question 3

A user's Windows 98 desktop icons are all showing generic document icons instead of their proper application icons after installing new software. What should you do first?

Accepted Answer

Rebuild the icon cache by deleting ShellIconCache

Answer

Windows 98 caches icons in the ShellIconCache file; deleting it forces Windows to rebuild the cache and restore proper icons on the next restart.

Question 4

A Windows 98 machine is infected with a boot-sector virus. The antivirus software reports it cannot clean the virus while Windows is running. What is the correct approach?

Accepted Answer

Boot from a clean write-protected antivirus floppy disk and run the scanner

Answer

Boot-sector viruses load before Windows; scanning from a clean, write-protected boot floppy bypasses the infected MBR and allows the antivirus to remove the virus safely.

Question 5

After upgrading a PC from Windows 95 to Windows 98, the user reports that their USB scanner no longer works. Windows 95 never supported USB. What is the most likely issue?

Accepted Answer

The USB driver or INF file for Windows 98 is missing and must be obtained from the manufacturer

Answer

While Windows 98 added native USB support, legacy devices from the Windows 95 era often need updated Windows 98-specific drivers from the hardware manufacturer.
