W7 64 Home: Task Scheduler looking for remote computer, can't defrag.

Question

Needed to defragment HD, went to task scheduler, found that it is looking for a remote computer and options to schedule tasks are grayed out.
The option in the right panel for the local computer was selected (there are no "apply" buttons or such).  Closed Task Scheduler, reopened, found that it is still looking for a remote computer, options to schedule tasks still grayed out.
Logged in as Admin. Not on a network.
Thank you

In Windows 7, Disk Defragmenter runs at regular intervals when your computer is turned on, so you don't have to remember to run it. It's scheduled to run once a week at an early hour in the morning. However, you can change how often Disk Defragmenter runs,
and at what time of the day.
Open Disk Defragmenter by clicking the Start button .
In the search box, type Disk Defragmenter, and then, in the list of results, click Disk
Defragmenter.‌  If you're
prompted for an administrator password or confirmation, type the password or provide confirmation.
Click Configure schedule, and then do one of the following:
To change how often Disk Defragmenter runs, click the menu next to Frequency, and then click Daily, Weekly,
orMonthly.
If you set the frequency to Weekly or Monthly,
click the menu next to Day to choose the day of the week or month that you want Disk Defragmenter to run.
To change the time of day when Disk Defragmenter runs, click the menu next to Time, and then choose a time.
To change the volumes that are scheduled to be defragmented, click Select disks, and then follow the instructions.
Click OK.
