Does the print spooler run on stand-alone Windows installations?
Yes. It's on all Windows computers, and is enabled to run by default.
Turning it off (disabling it) requires administrator-level permissions, but most standalone Windows systems have a single user (the one who set it up, or first logged in) who is an administrator.
#11 Yes and if you disable the Print spooler then you cannot print.
Yes, and it’s enabled by default. You can run “services.msc” from the “Run” section of the Start Menu to see what services are running, then change the “Start Up Type” to “Disabled” to turn it off.
