I found another way to work around this limitation in Windows 7. You'll need to create a custom MMC console and add each remote computer to it. If you normally manage several computers, this actually wouldn't be so bad, but if you were doing a one-off task, it's not the quickest method.
- Open up an empty MMC console (mmc.exe).
- File --> Add/Remove Snap-in --> scroll down and select "Task Scheduler" --> Add --> select "Another computer" --> type the remote computer's name --> OK --> OK.
- File --> Save As --> save the custom MMC console.
Now whenever you open up that MMC, you'll see the scheduled tasks for the remote computers that you added. Note that it could take a minute or so to bring up the Task Scheduler for the remote computers. On the left pane you'll see Task Scheduler (<remote-computer-name>) and then under that will be Task Scheduler Library with all the scheduled tasks.
Note: I only tested by adding one remote computer to the console, but it looks like several can be added.
