The correct way to disable System Restore involves accessing the System Properties dialog, which is accessed via the Control Panel. From there, navigating to the 'System Protection' tab and choosing the appropriate drive configurations ensures that System Restore can be turned off for specific drives, where changes are confirmed by applying the modifications. This process is essential for ensuring that malware does not remain in the system by eliminating the possibility of reverting to a system state that might still be infected.

Event Viewer shows all the logs and activities on your system. It can be accessed by searching "Event Viewer", or start > control panel > administrative tools > event viewer.

A server lock can be used to lock away sensitive servers and network devices. Typically this comes in the form of a server rack with a locking door. This is a common security measure to prevent unauthorized physical access to servers if they are in a shared datacenter or location where unauthorized users could have access.

If the employee is adhering to usage policies and has not installed new applications, then the most likely reason for the data overages could be background data usage by applications or system services. Investigating the detailed cellular data usage in the device settings is the logical first step as it can reveal which applications or system services are using unexpected amounts of data despite the user's activities. An application update might not directly correlate to data usage limits, and malware is less likely without new application installations or other symptoms. Changing the user's data plan does not address the root cause and should be considered after other troubleshooting steps.

Performance monitor is a Windows tool that can be used to monitor and log a system's health and status in real time. Task Manager can display similar information but does not log and should only be used as a quick reference.

Scripts that do not properly manage system resources, such as memory, can cause leaks that over time degrade system performance and lead to crashes. If a script allocates memory and fails to release it after execution, it becomes a memory leak. Repeated runs of such scripts can exhaust available memory, causing instability and potential system or browser crashes. Ensuring that scripts manage resources correctly is crucial to maintaining a stable system.

The NET command in Windows provides many options, including the NET USE command tool. The NET USE command will show and configure mapped network drives from a shared resource like a NAS or a storage server.

Shoulder surfing is a common tactic to gain information by standing near a person as they talk on the phone, fill out a form, or type in their password.

Using Microsoft Remote Assistance (MSRA), the technician can request to control the client's computer with the client's permission and demonstrate the proper installation and configuration process. The client will only need to accept the invitation, making it straightforward for users without extensive technical knowledge. Other options, like VPNs and SSH, require more client involvement and knowledge, and are therefore not the best fit for this scenario.

Restarting the 'Print Spooler' service is often the best initial step to resolve issues related to network printers appearing offline. This service manages print jobs and restarting it can clear any stuck jobs or refresh the connection to network printers. Checking cables from the printers or reinstalling printer drivers might also help but are usually secondary steps after ensuring the services are running correctly.

Disabling Universal Plug and Play (UPnP) on a wireless router can significantly enhance the security of a network. UPnP can be exploited by malware to open ports without a user's knowledge, potentially allowing external threats to penetrate the network. Therefore, disabling it reduces the risks of such vulnerabilities. Changing the SSID does not inherently secure the network—this action just changes the network name. While disabling SSID broadcast may somewhat obscure the network from casual discovery, it is not a robust security measure as SSID can be discovered by more determined attackers using simple tools. Port forwarding/mapping is typically used to allow external devices to access services within the private network and is not a method to enhance network security.

An Acceptable Use Policy (AUP) is a document often given by employers to their employees and contractors prior to being given access to company networks and equipment. It dictates what users can and cannot do, for example it will likely state users are expected to follow the law, that certain types of websites are not permitted, etc.

An in-place upgrade is an installation type that updates an existing operating system while keeping things like files, applications and settings from the existing operating system.

In Microsoft Active Directory a Group Policy is a policy applied to many AD objects. Objects can be user accounts, servers, desktop devices, etc. Group Policies are used to manage things like user account permissions. For example, a policy may be created for each team with default account permissions needed for those users.

Changing the account password will most likely solve the issue, but better preventatives should be put in place as soon as possible. Spam filters typically ignore local emails, which is why this is not the correct answer.
