Windows 7 provides a wide range of tools to help you
maintain your computer. They include the following:- Automatic Updates
Allows you to keep your computer up-to-date with the latest
hot fixes and security updates
- Disk Cleanup
Allows you to check disk drives for files that aren’t
needed
- Check Disk
Allows you to check disks for errors in the filesystem and on
the disk volume itself
- Disk Defragmenter (Dfrg.msc)
Allows you to optimize disk performance by reducing
fragmentation of files
The following sections discuss how you can use each tool to perform
preventive maintenance and routine checkups on your computer.
1. Updating Your Computer
Ensuring that your computer is up to date with the most recent hot
fixes, security updates, and service packs is the most important
preventive maintenance task you can perform. The great news is that you
can completely automate the update process so that as updates become
available, you can have your computer automatically download and install
them.
The feature in Windows 7 that handles updates is called Windows
Update. Windows Update is an enhanced version of the standard automatic update feature included in earlier releases of
Windows. With Windows Update, you can be sure that all operating system
components and related programs that ship with the operating system are
updated automatically. If you installed the Windows Live desktop
programs, these can be updated automatically as well.
You can even take this process a step further by having your
computer download and install updates for related Microsoft products,
including Microsoft Office, via an extension component called
Microsoft Update. Microsoft Update extends Windows Update to provide a total
update shield for your computer and key Microsoft products.
1.1. Installing Microsoft Update
When you install some Microsoft products, Microsoft
Update is downloaded and installed automatically. For example, if you
downloaded and installed the Windows Live desktop programs, Microsoft
Update is installed automatically as part of the setup process.
You can determine whether your computer is using Microsoft
Update by following these steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
If your computer is configured to use Microsoft Update,
you’ll see the following message in the lower portion of the
page:
You receive updates: For Windows and other products from Microsoft Update.
You can install Microsoft Update by completing these
steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
Click the “Get updates for more products” link. This opens
the Windows Update page at the Microsoft web site in Internet
Explorer.
After you read about Microsoft Update, scroll down, select
“I accept the Terms of Use,” and then click Install.
NOTE
When you are using Microsoft Office, related Office
applications, Visual Studio, and some other Microsoft products,
you’ll want to use Microsoft Update to ensure that your computer
downloads and installs updates for these programs according to your
Automatic Updates settings. This will help ensure security patches,
updates, and service packs for these applications are installed as
they are released.
1.2. Configuring Automatic Updates
You can configure Automatic Updates by completing these
steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
In the left panel, click “Change settings.” This displays
the “Change settings” page, shown in Figure 1.
You can now specify whether and how updates should occur. To
download and install updates automatically, select “Install
updates automatically” and then set the interval for installing
updates. By default, your computer periodically checks for and
downloads updates when you are connected to the Internet. However,
updates are installed only on the specific days and times you set.
If you shut down your computer after updates have been downloaded,
the updates are installed automatically before the computer shuts
down, unless you elect to shut down without installing
updates.
To ensure that recommended updates for device drivers
included with the operating system and other optional updates are
downloaded when they are available, select the “Give me
recommended updates the same way I receive important updates” checkbox. Recommended
updates are not installed automatically. Instead, you are notified
when recommended updates become available.
To ensure that you receive updates for other Microsoft
products and periodically check for new optional software from
Microsoft, select the “Give me updates for Microsoft products and
check for new optional Microsoft software when I update Windows”
checkbox.
To receive detailed notifications about optional software
from Microsoft, select the “Show me detailed notifications…”
checkbox.
Click OK to save your settings.
1.3. Checking for updates
You can check for and install updates manually at any
time by following these steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
As shown in Figure 2,
statistics are provided regarding the most recent check for
updates, the last time updates were installed, and the current
update configuration. If you want to check manually for updates,
click “Check for updates.”
If updates are available, they are downloaded. To install
downloaded updates, click “Install updates.”
1.4. Viewing update history
You can view a detailed update history and a list of
both successful and failed updates by following these steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
In the left panel, click “View update history.” This
displays the History page shown in Figure 3.
On the History page, updates listed with a Successful status
were downloaded and installed. Updates listed with an Unsuccessful
status were downloaded but failed to install.
To remove an update while accessing the History page, click
Installed Updates. Then on the Installed Updates page, right-click
the update that you do not want and select Uninstall.
1.5. Removing updates and resolving update problems
Occasionally your computer may experience problems due
to installing updates. Although this happens rarely, it does happen.
You can remove updates if you need to by following these steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
In the left panel, click “View update history” and then
click Installed Updates.
Select the update you want to modify or remove and then
click Change or Uninstall as appropriate.
A problem I’ve experienced several times with
Automatic Updates occurs due to a conflict between McAfee Security Center and Automatic Updates. As this
is an equal opportunity conflict, I’ve also seen it occur due to a
conflict between Norton Security and Automatic Updates. Normally, when
you shut down your computer and there are updates to install, these
updates are installed automatically. The problem I’ve experienced is
that the update process gets locked when I shut down my computer,
and there are multiple updates that affect components protected by
McAfee or Norton as part of their antivirus or antimalware
protection. To shut down my computer, I had to press and hold the power
button—something you should
never do when updates are being installed. When I later started my
computer, the computer froze as soon as either McAfee or Norton
started, and I was at a complete standstill. If you experience this
problem, too—and you might—you’ll need to boot your computer to Safe
Mode |

1.6. Restoring declined updates
If you decline an update that you later want to install,
you can restore the update so that you can install it by completing
these steps:
Click Start→All Programs→Windows Update. This displays the
Windows Update page in the Control Panel.
In the left pane, click “Restore hidden updates.”
On the Restore Hidden Updates page, select an update you
want to install and then click Restore.
Windows 7 will unhide the declined update. Click Back to
display the main Windows Update page, and then click “Install
updates” to install the previously declined update.
