I was checking some of my schedule task jobs using MMC, and then a thought come to my mind, that there should be some cmdlet by which I can check all of my schedule task jobs, isn't ( Ok, there are thousand's of cmdlets, and you can't know each and everyone, so don't laugh, .. I said DONT LAUGH)
I have found a cool cmdlet for it, Get-Scheduledtask , type and run it and you will see list of you all cmdlets and if you wannt know about the running schedule tasks, then you now ( I am assuming, that you are inteliggent, LOL) you have to use Where-Object cmdlet. Simple!
Get-Scheduledtask | where state -eq "Running"
