The office PC in the other room needs a restart and nobody is sitting at it. If you are its administrator, the built-in shutdown command can do it from your desk — no remote desktop session needed. Here is the exact syntax, and the honest list of reasons it often fails the first time.
Adding /m \\computername aims the shutdown command at another Windows PC on your local network instead of your own. It is the same tool from the video, used the way IT admins have used it for years: shutdown /r /m \\OFFICE-PC /t 60. Two honest conditions decide whether it works at all — you must have administrator rights on that PC, and its firewall must allow the request. Everything else is detail.
shutdown /r /m \\OFFICE-PC /t 60 /c "Restarting for updates, please save your work"/r — restart (use /s for a full shutdown you cannot undo remotely without Wake-on-LAN)/m \\OFFICE-PC — the target. Replace OFFICE-PC with the PC's real network name and keep both backslashes/t 60 — give the person at that desk 60 seconds of warning; a remote /t 0 is technically allowed and socially terrible/c "..." — the reason shown to the user in the warning box, so it is not a mystery restartRun it from CMD on your PC, signed in with an account that is an administrator on the target PC. The target shows the countdown warning, then restarts.
None of these are fixed by typing the command harder. They are permissions and network conditions — fix the condition, and the same command succeeds.
/r over /s when nobody is at the target. A shut-down remote PC stays off until someone physically presses its power button, unless Wake-on-LAN is set up./t and /c give them — nothing more. Their unsaved work is closed with force behaviour on a timer, so the warning time is a real responsibility, not decoration.If you fired it at the wrong PC or the user calls you in a panic, the abort switch works remotely too:
shutdown /a /m \\OFFICE-PC while the countdown is still runningLike the local version, abort only works during the countdown — another reason to never send /t 0 to a machine with a human sitting at it.

▶️ Watch Full VideoOnly PCs where your account has administrator rights and whose firewall allows remote shutdown. In practice that means your own PCs and office PCs you manage. A random PC on the network will answer with Access is denied.
Nothing, in effect — the same shutdown happens. The /m form simply sends the instruction over the network, which is why permissions matter. It saves the walk; it does not bypass the target PC's security.
Check the computer name is exact, the target is switched on and awake, and you are on the same network or VPN. A sleeping PC with no Wake-on-LAN cannot hear the command at all.
