PowerShell is a scripting language that can interact with Active Directory and other Windows components. It has a built-in cmdlet called New-ADUser that can create user accounts in Active Directory. PowerShell can also use the Active Directory module to access other AD-related functions and attributes. Other languages, such as Bash, SQL, and PHP, are not designed for creating Active Directory accounts and would require additional tools or libraries to do so.

Group Policy is a feature of Windows that allows administrators to manage and configure settings for computers and users on a network12. One of the settings that can be controlled by Group Policy is the password policy, which defines the rules for creating and changing passwords, such as minimum length, complexity, expiration, and history34. By using Group Policy, the Chief Information Officer can enforce the new password length requirement for all users and computers in the company’s domain, without having to manually adjust each user account or device.

The sfc command is a tool for scanning and repairing system files that are corrupted or missing on Windows operating systems12. System files are essential files that are required for the proper functioning of the operating system, such as the GUI, drivers, services, and applications. If system files are damaged or deleted, the operating system may fail to start or run properly, causing errors, crashes, or blue screens.

The sfc command can be used to fix the issue of the PC that is unable to start the GUI, assuming that the problem is caused by corrupted or missing system files. The sfc command can be run from the command prompt, which can be accessed by booting the PC from the installation media, choosing the repair option, and selecting the command prompt option3. The sfc command can be used with different switches, such as /scannow, /verifyonly, /scanfile, or /offbootdir, depending on the situation and the desired action4. The most common switch is /scannow, which scans all the system files and repairs any problems that are found5. The syntax of the sfc command with the /scannow switch is:

sfc /scannow

The sfc command will then scan and repair the system files, and display the results on the screen. If the sfc command is able to fix the system files, the PC should be able to start the GUI normally after rebooting. If the sfc command is unable to fix the system files, the PC may need further troubleshooting or a clean installation of Windows.

The most likely causes of the user’s Windows computer performance degradation and freezing are insufficient RAM and excessive software running in the background. Therefore, the technician should do the following to resolve the issue:

Increase the RAM. RAM is the memory that the computer uses to store and run applications and processes. If the RAM is not enough to handle the workload, the computer will use the hard drive as a virtual memory, which is much slower and can cause performance issues. Increasing the RAM will allow the computer to run more applications and processes smoothly and avoid freezing. The technician should check the system requirements of the applications that the user needs to run, and install additional RAM modules that are compatible with the motherboard and the existing RAM. The technician should also make sure that the system is managing the page file size automatically, or adjust it manually to optimize the virtual memory usage12.

Uninstall unnecessary software. Software that the user does not need or use can take up valuable disk space and system resources, and can interfere with the performance of other applications. Some software may also run in the background or start automatically when the computer boots up, which can slow down the system and cause freezing. The technician should help the user to identify and uninstall unnecessary software from the control panel or the settings app, and disable unnecessary startup programs from the task manager or the system configuration tool. The technician should also check for and remove viruses and malware that may affect the system performance134.
