Features window opens.

All Programs, then click Windows
Defender.

Running the Disk Cleanup
Program
The Disk Cleanup program frees up space on your
hard disk drive by removing temporary and unused
files (including temporary Internet files and files in the
Recycle Bin). You can run Disk Cleanup manually, or
you can set it up to run automatically.
Running Disk Cleanup manually
1 Click the Windows Vista start button,
All Programs, Accessories, System Tools,
and then click Disk Cleanup.
Disk Cleanup searches for files to delete and
calculates how much disk space can be saved.
2 Place a check mark in the check box next to the
file types you want to delete.
3 Click OK, and then click Delete Files to finish
deleting the selected files.
Scheduling Disk Cleanup to run
automatically
1 Click the Windows Vista start button,
All Programs, Accessories, System Tools,
and then click Task Scheduler.
2 Click Action, and then click Create
Basic Task.
3 Type a name for the task, and an optional
description.
4 Click Next, and then click Next again.
5 Select the reoccurrence, and click Next.
6 Select the time at which to run Disk Cleanup, and
click Next. Disk Cleanup may take a long time,
so select a time when the computer is on but not
in use.
7 Select Start a program, and click Next.
8 Under Program/Script, click Browse.
9 Type cleanmgr.exe, and click Open, and
then Next.
10 Review the summary of the schedule you set.
When you are done, click Finish. Disk Cleanup
will run at the time you set.
NOTE: Some programs have their own uninstall
features. If you cannot uninstall a program from the
Control Panel, refer to the program documentation or
online Help.
