Best way to install Vista SP2

<http://www.microsoft.com/communities/newsgroups/en-us/default.aspx?&lang=en&cr=US&guid=&sloc=en-us&dg=microsoft.public.windowsupdate&p=1&tid=6e36e 628-c81d-408d-8d30-4ba37d6b2a0d&mid=6e36e628-c81d-408d-8d30-4ba37d6b2a0d>


If you're having problems installing SP2 *via Windows Update*, you can also
post about your problems here instead:
<http://social.answers.microsoft.com/Forums/en-US/vistawu/threads/>

Please post any other Vista SP2-related questions in a Vista-specific
newsgroup (e.g., Vista General) or either of these 2 forums:
<http://www.answers.microsoft.com/windows> ;

Installation Tips:

• Your computer will restart several times during the installation process:
Make certain you've saved your work and closed all open applications before
beginning the install.

• Disable
(1) your anti-virus application,
(2) any real-time system protections afforded by any anti-spyware
applications (except Defender), &
(3) your third-party firewall (if any) and then
(4) enable the Windows Firewall before installing or uninstalling
Vista SP2.

• The installation process can take an hour or more: If you're installing
SP2 on a portable computer, make sure that you plug-in the power cord and
have the battery inserted into its bay.

• Vista SP1 is a prerequisite for installing SP2. If you use Windows Update
or the Automatic Update feature in Windows Vista, you will not be offered
the option to install SP2 until you first install SP1.

select appropriate category (i.e., Download issue; Installation issue;
Issues after you install a service pack).
