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.

The symptoms that the user’s Windows computer is experiencing suggest that the new software program that the user installed from an external website may be malicious or incompatible with the system. The program may be consuming a lot of CPU resources, slowing down the performance of other programs and files. The program may also be altering the browser settings or the HOSTS file, causing the web redirection to an unauthorized site. The first step that the technician should do is to uninstall the new program from the Control Panel or the Settings app, and then restart the computer. This may resolve the issue and restore the normal functionality of the computer. If the problem persists, the technician may need to perform additional steps, such as scanning for malware, checking the HOSTS file, clearing the web browser cache, or restoring from a previous backup

The hostname command-line tool is used to display the name of the local machine. This information can be crucial for identifying the device within a network, especially when setting up remote access or sharing resources like folders and printers. Unlike other command-line tools that provide more detailed network diagnostics or configuration details, hostname straightforwardly offers the device's network identification, making it suitable for the scenario described.References: Official CompTIA A+ Core 1 and Core 2 Student Guide​​.

Some electronic items require special e-waste recycling because they contain hazardous materials that can harm the environment and human health if disposed of improperly12. Laptop batteries and CRT monitors are examples of such items.

Laptop batteries are usually made of lithium-ion or nickel-metal hydride, which are both toxic and flammable substances34. If laptop batteries are thrown in the trash, they can leak, catch fire, or explode, causing pollution and injuries5 . Therefore, laptop batteries should be recycled at authorized collection centers or through manufacturer take-back programs .

CRT monitors are old types of display devices that use cathode ray tubes, which are glass tubes that emit electrons to create images on the screen . CRT monitors contain lead, mercury, cadmium, and phosphor, which are all harmful metals that can contaminate the soil, water, and air if dumped in landfills . Therefore, CRT monitors should be recycled at certified e-waste facilities or through retailer or manufacturer trade-in programs .

The best solution for a technician to implement is to disable the browser from sending notifications to the Action Center. This will prevent the random advertisement notifications from appearing in the Windows 10 Action Center, which can be annoying and distracting for the user. The technician can follow these steps to disable the browser notifications1:

Open the browser that is sending the notifications, such as Microsoft Edge, Google Chrome, or Mozilla Firefox.

Go to the browser settings or options menu, and look for the privacy and security section.

Find the option to manage site permissions or notifications, and click on it.

You will see a list of sites that are allowed or blocked from sending notifications to the browser and the Action Center. You can either block all sites from sending notifications, or select specific sites that you want to block or allow.

Save the changes and close the browser settings.

This solution is better than the other options because:

Running a full antivirus scan on the computer (B) is not necessary, as the advertisement notifications are not malicious or harmful, and they are not caused by a virus or malware infection. Running a scan will not stop the notifications from appearing, and it will consume system resources and time.

Disabling all Action Center notifications © is not advisable, as the Action Center is a useful feature that shows notifications and alerts from various apps and system events, such as email, calendar, security, updates, etc. Disabling all notifications will make the user miss important information and reminders, and reduce the functionality of the Action Center.

Moving specific site notifications from Allowed to Block (D) is not the best solution, as it will only stop the notifications from some sites, but not from others. The user may still receive advertisement notifications from other sites that are not blocked, or from new sites that are added to the Allowed list. This solution will also require the user to manually manage the list of sites, which can be tedious and time-consuming.

Setting the connection to be metered is the best solution for limiting the amount of cellular data a user’s Windows 10 tablet can utilize when traveling. A metered connection is a network connection that has a data limit or charges fees based on the amount of data used. Windows 10 allows users to set any network connection as metered, which reduces the amount of data that Windows and some apps use in the background. For example, setting a connection as metered will prevent Windows from downloading updates automatically, stop some apps from syncing data online, and disable some live tiles on the Start menu. Setting a connection as metered can help users save cellular data and avoid extra charges when traveling. Turning on airplane mode, configuring the device to use a static IP address, and enabling the Windows Defender Firewall are not effective solutions for limiting the amount of cellular data a user’s Windows 10 tablet can utilize when traveling. Turning on airplane mode will disable all wireless connections on the device, including Wi-Fi, Bluetooth, and cellular data. This will prevent the user from accessing any online services or applications on the tablet. Configuring the device to use a static IP address will assign a fixed IP address to the device instead of obtaining one dynamically from a DHCP server. This will not affect the amount of cellular data the device uses, and it may cause IP conflicts or connectivity issues on some networks. Enabling the Windows Defender Firewall will block or allow incoming and outgoing network traffic based on predefined or custom rules. This will not reduce the amount of cellular data the device uses, and it may interfere with some apps or services that require network access. References:

A corporate EULA is a type of end-user license agreement that is designed for a large organization that needs to use proprietary software with vendor support for a multiuser environment. A corporate EULA typically grants the organization a volume license that allows it to install and use the software on multiple devices or servers, and to distribute the software to its employees or affiliates. A corporate EULA also usually provides the organization with technical support, maintenance, updates, and warranty from the software vendor, as well as some customization options and discounts. A corporate EULA may also include terms and conditions that specify the rights and obligations of both parties, such as confidentiality, liability, indemnification, termination, and dispute resolution12.

A corporate EULA is a better option than the other choices because:

A perpetual EULA (B) is a type of end-user license agreement that grants the user a permanent and irrevocable license to use the software, without any time limit or expiration date. However, a perpetual EULA does not necessarily include vendor support, updates, or warranty, and it may not allow the user to install the software on multiple devices or servers, or to distribute the software to other users. A perpetual EULA may also be more expensive than a corporate EULA, as it requires a one-time payment upfront, rather than a recurring subscription fee34.

An open-source EULA © is a type of end-user license agreement that grants the user a license to use, modify, and redistribute the software, which is publicly available and free of charge. However, an open-source EULA does not provide any vendor support, maintenance, updates, or warranty, and it may impose some restrictions or obligations on the user, such as disclosing the source code, attributing the original author, or using a compatible license for derivative works. An open-source EULA may not be suitable for a large organization that needs proprietary software with vendor support for a multiuser environment56.

A personal EULA (D) is a type of end-user license agreement that grants the user a license to use the software for personal, non-commercial purposes only. A personal EULA may limit the number of devices or servers that the user can install the software on, and prohibit the user from distributing, copying, or reselling the software to other users. A personal EULA may also provide limited or no vendor support, maintenance, updates, or warranty, and it may have a fixed or renewable term. A personal EULA may not meet the needs of a large organization that needs proprietary software with vendor support for a multiuser environment7 .

The ext3 file system is a Linux native file system that meets the requirements of the question. It has the following features:

All changes are tracked. The ext3 file system uses a journaling mechanism that records all changes to the file system metadata in a special log called the journal before applying them to the actual file system. This ensures that the file system can be restored to a consistent state in case of a power failure or system crash12.

The possibility of file corruption is reduced. The journaling feature of ext3 also reduces the possibility of file corruption, as it avoids the need for a full file system check after an unclean shutdown. The file system can be quickly replayed from the journal and any inconsistencies can be fixed12.

Data recovery is easy. The ext3 file system supports undeletion of files using tools such as ext3grep or extundelete, which can scan the file system for deleted inodes and attempt to recover the data blocks associated with them34.
