Scheduler: Schtasks /? will give you the commands...
schtasks /create /ru system /sc once /st 09:00:00 /tn MyTest /tr "notepad.exe"
will create a task to run once at 9am....
mstsc is the command line version for remote desktop.
You can get other shortucts by scanning
C:\windows\system32 - for all .cpl * .msc files..
Examples (from a command prompt):
appwiz.cpl (add/remove programs)
desk.cpl (display properties)
sysdm.cpl (my computer properties)
lusrmgr.msc (user/groups management)
compmgmt.msc (computer management)
fsmgmt.msc (file shares management)
diskmgmt.msc (disk manager)
devmgmt.msc (device manager)
etc
I use these nearly every day! Great shortcuts. ;^ )
