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
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.

on this list. We are more interested in the
available System Files.

click the Clean Up System files button.
