54. Remove Service Pack Backup Files
When installing Windows 7 Service Pack 1 you not only install the
updates but you also end up with numerous Backup
files. These backup files, in most cases, simply sit on your hard
drive taking up valuable disk space. Windows 7 service Pack 1, for
example, leaves behind around 650MB of backup files after the
service pack has been installed.
Many users simply think no more about these backup files,
preferring to leave them where they are regardless of how much disk
space they take up. Other users, however, prefer to get rid of the
backup files, especially if they happen to be low on disk space.
Whether you actually remove the backup files or not is entirely
up to you. One disadvantage of removing the backup files is that, by
doing so, you make it impossible to actually uninstall the service
pack should you find it necessary to do so.
To actually remove the backup files is simple enough. Two methods
are available; using a command prompt or using
Windows built in Disk Cleanup application. The
Windows Disk Cleaner option is by far the simpler and so we will
outline how to remove the backup files using the Disk
Cleanup option.
- Click the Start button and in the Start
Menu Search Box type: Disk Clean.

- The Disk Cleanup application will appear as a
highlighted
option at the top of the Search list. Press the
Enter key to
start the application.
- Before you can start removing files you need to select
the
relevant hard drive. By default the C: drive is selected.

- Disk Cleanup will now calculate how much space it can free
up.

Fig: 54-3 Calculating how much space can be freed may take a few
minutes, so be patient
- A list of available files that can be deleted will now
appear.
- While this list is important, at this stage we are not
particularly bothered about the files on this list. We are more
interested in the available System Files.
- To see what System Files can be deleted, click the
Clean Up
System files button.

that can be deleted.
- You will need to select the drive you want to clean once
again and click the OK button

Fig: 54-5 Select the drive and press the OK button to continue
- Once again Disk Cleanup will calculate how much space it can
free up.

space it can free up once again
- A list of available files will, once again, appear. This
time you need to look down the list until you come to the
Service Pack Backup Files option.
- Once you have located the Service Pack Backup Files option,
place a check mark (Tick) in the box to the left of the option
and the press the OK button.

Fig: 54-7 Place a check mark next to the Service Pack Backup Files
option to enable it
- A message will now appear asking you if you are sure you
want to permanently delete these files. If you do then click the
Delete files button.

Fig: 54-8 Click the Delete Files button to start the deletion
- A progress window will now appear. Once the files have been
deleted this window will disappear and all the files you
selected will have been permanently deleted.
