Primary Learning Objective Execute Routine System Management MCT 260 -Operating Systems I 2

Specific Learning Objectives • Identify and define the terms associated with system management • Identify critical system files used by operating systems • Add/remove software and Windows components • Install a Printer • Use Task Manager to end unresponsive programs and view CPU/memory usage MCT 260 -Operating Systems I 3

Specific Learning Objectives • Use Windows Internet Update Feature and Device Manager • Restore your computer • Modify system variables such as date and time • Use CLI commands such as SET, DATE, TIME, VER, and MEM MCT 260 -Operating Systems I 4

Critical System Files • As OS’s have evolved, so has the way they store configuration information. The older, smaller files are still important because they are used for bootable and network connection disks. • The three following files are the minimum required to make a bootable (startup) disk: – COMMAND. COM – IO. SYS – MSDOS. SYS MCT 260 -Operating Systems I 5

Critical System Files • After a DOS computer boots up, it reads the CONFIG. SYS, a configuration file, and executes any commands in it. • Next the AUTOEXEC. BAT (automatically executed batch) file runs. • Windows 3. x used initialization files (. INI) for software settings. WIN. INI and SYSTEM. INI are two that are still important in network connection disks. MCT 260 -Operating Systems I 6

The Registry • The. INI files were replaced by the registry in Windows 95. • The Registry is a database used by the Windows operating system to store configuration information. • Stores all settings for: Users, Hardware, Programs, and Folders • Software and hardware installations affect the registry MCT 260 -Operating Systems I 7

Adding Software • Read the instructions and/or Readme files • Three options exist for adding software: – Newer programs come on CD-ROMs. If it has an auto-run feature, the installation program will start automatically. – Start > Control Panel > Add or Remove Programs > click the Add New Programs button then click the CD or Floppy button. If it can find the SETUP or INSTALL program it will run it. – Open the disk /folder and double-click any files called SETUP or similarly named files. MCT 260 -Operating Systems I 8

Adding New Programs MCT 260 -Operating Systems I 9

Removing Software • The preferred method is to use Add or Remove Programs since it removes all traces of the program even in the Registry. • Another option is to see if the program has its own uninstall program and run it. • The worst option is to delete the files and folder where the program is located MCT 260 -Operating Systems I 10

Removing Programs MCT 260 -Operating Systems I 11

Adding/Removing Windows Components • In Add or Remove Programs click Add/ Remove Windows Component button • Check the category that contains the component you need to add. • Clicking the DETAILS button show a list of individual components in that category. MCT 260 -Operating Systems I 12

Configuring Components MCT 260 -Operating Systems I 15

Installing a Printer • Local printer – one connected to the computer’s parallel port • Network printer – one connected directly to the network or to a print server • Having the correct printer driver is very important for a successful installation. – Generally older printer drivers are easily found on the OS CD-ROM – New printers with older OS’s can cause problems MCT 260 -Operating Systems I 16
