@mary said in Windows Administrative Tools - CompTIA A+ 220-1002 Prof Messer: Is there a list anywhere of the Windows command prompts, or do you usually look at the help to look at options? I realize the more seasoned IT person would have a lot of these committed to memory, but just starting out this is a bit overwhelming. There seem to be a lot of them to keep track of. Kind of. There are some built in tools to the shell itself, and some standard Windows tools that you can call. but keep in mind that you can add an unlimited number of additional ones, because all you are doing is calling installed applications. So while there are lists of the ones built in, most people have loads and loads of ones that are not.

@mary said in Network Command Line Tools - CompTIA A+ 220-1002 Prof Messer: Is it ok to have any packet loss when pinging another computer? It's not a crime or anything There is always "some" packet loss, but in a healthy network it is super low, like one out of one hundred thousands packets. If you are doing a ping and seeing packets missed regularly, something is wrong. On a wired network, this implies bad equipment, cabling, or EM interference. On wireless it means your signal isn't clean. Obviously wifi is going to lose packets way more than a cabled connection, and copper way more than optical. But it should still be essentially zero on a healthy network.

@mary said in Microsoft Command Line Tools - CompTIA A+ 220-1002 Prof Messer: Can you remote in to restart a PC if it is frozen or are you stuck looking at what the user is? Depends on the tools at your disposal and where "you" are. You can remote in using tools like RDP, but if the user is frozen, likely that won't help. You can remote in using PsExec, PowerShell Remoting or SSH and those will often work if the OS isn't completely frozen. You can use tools like ScreenConnect or MeshCentral, they will allow for remote command execution through local agents. And DevOps tools like SaltStack will issue remote commands similarly. But it all depends on your level of remote access, what has been set up ahead of time, and how frozen things are.

@scottalanmiller said in Installing and Upgrading Windows - CompTIA A+ 220-1002 Prof Messer: ot crippled from having been upgraded rather than being a fresh install. So at least they appear to have fixed something in their I would agree with Jared and Scott when it comes from a Windows 10 to Windows 10 newer version upgrade... not so much when coming from Windows 7, 8, 8.1. Personally I'd still wipe and reload after an upgrade from any of those OSes... who know what old crap was still around from those installs. But like JB and Scott - Win 10 to Win 10 - generally OK once you get it there.
