How do I figure out the display name of a Windows service from its "short" name?

"Try, on the command line:

sc query

and look through that. You could >redirect to a file, as so:

sc query > output.txt

and use a text editor to search through it (And seeing as this creates a comprehensive list of processes, you could keep it around)

Bonus point: If you have a version of grep installed, either from cygwin, or unxutils, or wherever, try:

sc query | grep -i -A 1 ""short name""

trying this with uxsms, the DWM service, I get

SERVICE_NAME: UxSms
DISPLAY_NAME: Desktop Window Manager Session Manager

To create a nice listing, you could use

sc query | grep -A 1 ""SERVICE_NAME"" > Services.txt"
