When troubleshooting boot times for a user, a technician may want to check which programs are starting with the operating system to identify any that may be slowing down the boot process. MSConfig is a tool that can be used to view startup items on a Windows system, but it may not always be available or functional.

In this scenario, the technician receives a message that MSConfig cannot be used to view startup items. As an alternative, the technician can use Task Manager (taskmgr), which can also display the programs that run at startup. To access the list of startup items in Task Manager, the technician can follow these steps:

Open Task Manager by pressing Ctrl+Shift+Esc.

Click the "Startup" tab.

The list of programs that run at startup will be displayed.

Checking for application updates is the first troubleshooting step that the user should perform, because the application may not be compatible with the new OS version and may need an update to fix the issue. Deleting the application’s cache, rolling back the OS update, or uninstalling and reinstalling the application are possible solutions, but they are more time-consuming and disruptive than checking for updates.

The most likely reason that the system is not utilizing all the available RAM is that it is running a 32-bit OS. A 32-bit OS can only address up to 4GB of RAM, and some of that is reserved for hardware and system use1. Therefore, even if the technician installed 8GB of RAM, the system can only use around 3.5GB of usable RAM. To use the full 8GB of RAM, the technician would need to install a 64-bit OS, which can address much more memory2. The system missing updates, the system’s memory failing, or the system requiring BIOS updates are not likely to cause this issue.

Resetting the network adapter is the best way to apply the changes made to the hosts file on a few PCs. The hosts file is a text file that maps hostnames to IP addresses and can be used to block certain domains by redirecting them to invalid or local addresses. Resetting the network adapter will clear the DNS cache and force the PC to use the new entries in the hosts file.
