The risks in running this script are that the deployment script is performing unknown actions. Running the script blindly could cause unintended actions, such as deploying malware or deleting important files, which could negatively impact the organization's network and data1.

devmgmt.msc is the MMC snap-in that opens the Device Manager, a tool that allows the technician to view and manage the hardware devices and their drivers on the computer1. If the applications are not updating properly, it could be due to outdated, corrupted, or incompatible drivers that prevent the hardware from functioning normally. The technician can use the Device Manager to update, uninstall, rollback, or disable the drivers, as well as scan for hardware changes, troubleshoot problems, and view device properties2.
gpedit.msc is the MMC snap-in that opens the Group Policy Editor, a tool that allows the technician to configure the local or domain group policy settings for the computer or a group of computers3. Group policy settings can affect the security, performance, and functionality of the system, but they are not directly related to the application updates or the hardware drivers.
perfmon.msc is the MMC snap-in that opens the Performance Monitor, a tool that allows the technician to monitor and analyze the performance of the system and its components, such as processor, memory, disk, network, etc4. Performance Monitor can display real-time data or collect log data for later analysis, as well as generate reports and alerts based on the performance counters5. Performance Monitor can help the technician identify and diagnose performance issues, but it does not provide a way to manage the hardware drivers.

When a user can access the local network (as evidenced by printing to network printers) but not the internet, the issue is often related to Domain Name System (DNS) resolution. DNS is responsible for translating domain names (like google.com) into IP addresses that computers use to communicate. If the DNS settings are incorrect or the DNS server is unreachable, the computer won't be able to find the IP addresses of websites and other internet resources.
