This
article describes the hard disk space that is required when you install
Microsoft Windows XP Service Pack 2 (SP2) on a computer that is already
running Microsoft Windows XP Home Edition or that is already running
Microsoft Windows XP Professional.
The following table lists the hard disk space requirements for Windows XP SP2.
| Hard disk space that is required if you install Windows XP SP2 from a shared folder on the network | Hard disk space that is required if you install Windows XP SP2 from the Windows XP SP2 CD |
---|
Service pack | 495 megabytes (MB) for the service pack | 495
megabytes (MB) for the service pack and an additional 500 MB for the
service pack files that are stored in the %Windir%\Servicepackfiles
folder |
Working space | 260 MB | 260 MB |
Files that remove Windows XP SP2 | 200 MB | 200 MB |
Total hard disk space required if the System Restore feature is enabled | 895 MB 1060 MB peak usage during installation | 1455 MB 1560 MB peak usage during installation |
Total hard disk space required if the System Restore feature is not enabled | 395 MB 770 MB peak usage during installation | 681 MB 1100 MB peak usage during installation |
In
this table, the "Working space" entry is the hard disk space that is
required for files that are used only during the installation process.
The working space requirement is temporary and does not contribute to
the total hard disk space requirement.
In this table, the
"Files that remove Windows XP SP2" entry is the hard disk space that is
used for storing the files and the settings that are changed during the
installation of the service pack. You can automatically back up the
files during the installation of the service pack. These files are
required if you want to remove the service pack later.
You
must also have 30 MB of free hard disk space on the first primary
system partition. The first primary system partition is the disk volume
that contains the hardware-specific files that are required to start
Windows. For example, the primary system partition contains the Ntldr
file, the Boot.ini file, and the Ntdetect.com file.
