You can troubleshoot a failed Windows startup/boot-up by pressing the F8 key to take you to the Advanced Boots Option Screen for more options as the system reboots. After exhausting most of the options there without success in resolving the boot issue, you decide to revert to a previously good working system configuration by choosing the Last Known Good Configuration (Advanced) option. Described the implications of doing so.
Explain why it is sometimes necessary to open the command prompt with administrative privileges.
Note-I will be denoting Last Known Good Configuration as LKGC.
I am answering the question in subparts in sequential manner.
Answer to subpart 1) —> Implication of choosing the Last Known Good Configuration(LKGC) is that when all the possible options for used up and windows did not boot up , then the only safe and appropriate option is LKGC.This is because it loads the drivers and registry data that worked the last time you successfully started and then shut down Windows.
Answer to subpart 2) —> It is sometimes necessary to open the command prompt with administrative privileges (which is termed as elevated command prompt) because there are situations when the user might need to open Command Prompt window as Administrator so that the user can execute the restricted commands such as enabling hidden Administrator account in Windows, fixing Windows 7 boot screen, etc.These advanced commands are not available in the command prompt without administrative privileges to prevent accidental execution of some advanced commands which can interact with Windows boot loader, etc.
