Describe two different ways to open a command prompt window, in a version of windows of your choosing. Using windows/file explorer: Go the drive where the windows is installed (mostly C: drive). Go the Windows folder. Inside Windows folder locate the System32 folder. Inside the System32 folder there is a file named cmd.exe Run the cmd.exe file and the command prompt opens. Using the Run window: Press Win+Ron your keyboard to open it. Then, typecmdorexeand pressEnteror click OK. 3. Using DOSs DIR command (or DIR /x, in same version of windows) on a computer that support long file name (LFNs) will also show MS-DOS-style 8.3 short filee names for those files with LFNs. Describe what Windows does to the LFN to make it into an 8.3 file name. The following steps are carried out to convert the LFNs to 8.3 file name: First characters like + , ; = [ and ] in LFN are converted to underscores _ in 8.3. Any Spaces are ignored in 8.3. Next the first 3 characters after aperiod (.)in LFN become the extension in 8.3. The first six characters of LFN are taken and converted to uppercase and the remaining characters are eliminated. After the first six characters ~1" is appended. If more file swith similar first six characters exit, then "~2", ~3 and so on are appended. If there are more than 9 files with the same first 6 characters, the tenth file becomes ~10, utilizing the last three characters. 4. When troubleshooting a computer running an early version of windows, it may be helpful to select safe mode when booting the computer. For Windows XP, describe One can use the Safe Mode Windows to load when you encounter a system-critical problem that is disturbing the normal operation of Windows. Safe Mode allows you to troubleshoot Windows and what is causing the windows to not function correctly. If the problem is corrected one can reboot the system in normal mode. If an existing problem doesn't appear when starting in safe mode, it is clear that the default settings and basic device drivers are not causing the problem. If you cant figure out the cause of the problem, then try starting all of the commonly used programs one by one, including the programs in your Startup folder, one of the programs might be the cause of the problem. Safe Mode differs from a normal mode in the following ways: In Safe Mode autoexec.bat / config.sys files are not run. Only minimal device drivers are loaded. Instead of using the normal graphics device driver, Safe Mode makes use of the standard VGA graphics mode. The Windows desktop in safe mode loads in 16 colors, with a resolution of 640 x 480 with the words "Safe Mode" in each corner. References Anon, 1986.
