Remove orphaned services that spam the event log after their software was uninstalled.

WindowssystemcmdserviceMedium risk
Run `sc delete "OldAppSvc"` in an admin prompt to remove the leftover service permanently.

01Command

Command
$ sc query "OldAppSvc"  ::  then, if it's safe:  sc delete "OldAppSvc"

02What it does

Uninstallers often leave their Windows service behind, which then fails at every boot and clutters the Services list. Check what the service belongs to with `sc query` and stop it with `sc stop` before deleting. The entry disappears from services.msc immediately after deletion (a reboot fully clears running remnants).
